Abstract

Background

Corporal punishment (CP) is still a common practice in schools globally. Although illegal, studies in South Africa report its continued use, but only a few have explored factors associated with school CP. Moreover, extant studies have not shown the interrelationships between explanatory factors. This study aimed to determine the prevalence and factors associated with learners’ experiences, and to examine pathways to the learners’ experiences of CP at school.

Method

3743 grade 8 learners (2118 girls and 1625 boys) from 24 selected public schools in Tshwane, South Africa, enrolled in a cluster randomised controlled trial evaluating a multi-component school-based intervention to prevent intimate partner violence, and completed self-administered questionnaires. We carried out descriptive analysis, simple linear and structural equation modelling to examine factors and pathways to the learners’ experience of CP at school.

Results

About 52% of learners had experienced CP at school in the last 6 months. It was higher among boys compared to girls. Experience of CP at school amongst learners was associated with learner behavior, home environment, and school environment. Learners from households with low-socio economic status (SES) had an increased risk of CP experience at school. Amongst boys, low family SES status was associated with a negative home environment and had a direct negative impact on a learner’s mental health, directly associated with misbehavior.

Conclusion

CP in public schools in South Africa continues despite legislation prohibiting its use. While addressing learner behaviour is critical, evidence-based interventions addressing home and school environment are needed to change the culture among teachers of using corporal punishment to discipline adolescents and inculcate one that promotes positive discipline.

Introduction

While the use of a physical methods of discipline, also referred to as corporal punishment (CP) at school is banned and no longer an issue in European countries; it continues to be prevalent in a third of the world’s countries, despite evidence regarding its harmful physical, mental and behavioural effects on the child [1, 2]. The global prevalence of CP in schools ranges between 13%– 97% of learners who reported experience of CP at school [1]. Learners continue to experience CP in most countries in Sub-Saharan Africa despite legislation prohibiting its use [1, 2]. The South African Schools Act No 84 of 1996 states that no person may administer CP to a learner at school [3]. Any person who administers corporal punishment at school is guilty of an offence and liable on conviction to a sentence which could be imposed for assault [3]. Corporal punishment has been an integral part of schooling for most teachers and learners in twentieth century South African schools, characterized by a legacy of authoritarian education practices under Bantu education, and a belief that CP is necessary for orderly education [4]. The ending of apartheid and the establishment of a human rights culture in the 1990s laid the foundation for legislation aimed at ending use of CP in schools in South Africa [4].

South Africa is a highly inequitable society and this inequality is reflected in the historically complex two-tier education system namely, the middle class, private schools and the public schools [5]. The middle class, formerly white schools no longer use corporal punishment as a discipline method [4]. However, in public schools, use of corporal punishment is still common practice [6, 7]. In most public schools, classrooms are overcrowded and under-resourced, and teachers are often under-qualified and overworked [8, 9]. Teachers feel disempowered and ill-equipped with viable alternative discipline methods to maintain a safe and secure environment which facilitates learning [6]. A national study conducted in 2012 showed that 49.8% of the 5939 learners had been caned or spanked by a teacher or principal in South African schools [10]. Use of CP in public schools in South Africa is a nation-wide problem that warrants further targeted research to inform prevention and responses [10].

Studies have been conducted to understand the reasons underlying the continued use of CP in schools in South Africa. CP is administered for both serious and minor offences such as being absent from school or not doing homework, not knowing the answer to the questions asked by teachers in class, caring a gun at school, and for talking or disrupting a lesson in class [6, 11]. Many teachers believe that CP is an effective method of correcting deviant behaviour and maintaining discipline in the classroom [12, 13].

While previous research has focused on determining the prevalence of learner experiences of CP in schools, limited research has focused on understanding what increases the risk of individual learners experiencing CP at school in South Africa. To contribute to this knowledge gap, we present analysis of quantitative baseline data collected from grade 8 learners who enrolled in a Skhokho Supporting Success randomised controlled trial (RCT) [14, 15]. The analysis aimed to determine the prevalence of CP experienced by learners in selected public schools in the last 6 months, and to examine factors associated with their experiences of CP at school. Using structural equation modelling, we elucidated pathways to the learners’ experience of CP at school. Understanding risk factors for learners’ experience of CP at school may provide much needed evidence to inform interventions to curb the continued use of CP by teachers.

Factors associated with experience of corporal punishment at school

Evidence from South Africa and elsewhere suggests that school CP is undergirded by a myriad of individual, school, family and broader community level risk factors [10, 16]. In a study conducted in Khayelitsha, a peri urban township in the Western Cape province in South Africa found that the transgressions that led to CP at school included not doing school or home work, coming late from break, not listening to teachers, giving wrong answers in class and making noise [7]. Boys were more likely to experience CP both at school and at home [16]. Learners who perform poorly at school are likely to be beaten by their teachers and by parents and caregivers at home with the aim to encourage improved academic performance [17]. Other studies suggest that children subjected to CP may engage in more aggression and misbehavior than those who are not [18, 19]. A large body of research on CP is on learners, and addresses the question of what makes them vulnerable, yet behaviour of teachers and what makes some teachers to use CP is also important. Research has shown that teachers who are overwhelmed with personal problems and believed that CP was effective in managing behavior in the classroom were likely to use CP against learners at school [20]. Contextual factors including low socio-economic class, ethnicity and race of learners were associated with experience of CP in public schools in the United States of America [21].

Family background, in particular, low socio-economic status is associated with experience of CP at school [16]. Children who experience financial lack, who are exposed to violence, and those who do not receive affection and love from home are likely to misbehave and to experience CP at school [20]. Food insecurity is also a risk factor directly associated with the experience of school CP amongst boys and girls [16]. Buller, Hidrobo [22] found that food insecurity and violence exposure is linked to increased levels of household stress over the lack of resources, which further leads to the use of corporal punishment.

There are broader community and societal influences to children’s experiences of CP. In communities where use of harsh discipline strategies is acceptable and where CP is perceived as effective in controlling behaviour, learners tend to be at increased risk of experiencing CP [23, 24]. Learners experiences of CP is also higher when the use of corporal punishment is justified to maintain discipline and to enable academic success [25, 26]. Related to this belief, is a positive correlation between one’s experience of CP during childhood, and the approval of its use as an adult [7, 25]. Childhood experience of CP legitimates violence by the stronger against the weaker and increases the chance of the child becoming violent [10, 27]. Exposure to violence and traumas in childhood which involves physical punishment has been found to increase the likelihood of being victimised or becoming a perpetrator in adulthood [28, 29]. While use of CP is illegal in South Africa, there has been limited concerted effort to enforce the law, ensuring that those who continue to use CP are convicted of an offense; and training of teachers on alternative methods of classroom management and discipline has been inadequate [30, 31]. Given this background, it is important that we understand why some children are more likely to experience CP than others.

Methods

Study design

The Skhokho Supporting Success primary prevention study was a cluster randomized controlled trial (RCT) that sought to develop and evaluate a multi-faceted school-based interventions to prevent intimate partner violence [14, 15]. The evaluation sought to show a reduced IPV incidence among learners in the intervention arm. The trial was conducted in 2015 and 2016 among secondary public schools located in Tshwane District, Gauteng Province, South Africa [14, 15]. Schools were randomized into three arms. The first arm received school strengthening including support for life orientation teaching (life skills, and guidance and counselling) and parent teenager relationship intervention; the second arm comprised of the school strengthening intervention only (including support for life orientation teaching); and the control arm received no intervention. The school strengthening intervention involved strengthening the institutional capacity of the school in teaching and practice of positive discipline, life skills and human rights and responsibilities [14, 15]. There were no significant differences in the number of learners and teachers in class.

Schools were selected if they were enrolling Grade 8 learners in 2014. All Grade 8 learners in 24 purposively selected English medium State secondary schools within a 50km radius from Pretoria City were eligible to participate in the study. While most (21 of 24) schools were located in black townships including Mabopane, Soshanguve, Hammanskraal, and Mamelodi, Winterveld and Atteridgeville, two were located in the central business district of Pretoria and one in Laudium, a predominantly Indian community [15]. Participants were recruited between February and April 2014.

Ethical considerations

The South African Medical Research Council Ethics Committee gave ethics approval for the trial. Permission to work in schools was given by the Gauteng Department of Basic Education (DBE), at the provincial and district level. Permission was also granted by the school principals in the 24 schools. The information letter detailing the nature and purpose of the study, the interventions, participants, what the project would offer to schools, risks and benefits of participating in the study, project timelines, and rights of participants was provided to principals. School principals were also informed that all data generated from the study will be kept confidential and that research reports and articles which will be submitted in scientific journals will not include any information that may identify the school or any of the educators, learners, school governing body officials and parents. All Grade 8s from the 24 schools were eligible to participate in the trial. Participants (learners) gave written assent and consent was obtained from their parents or caregivers before they were enrolled in the trial. All learners in Grade 8 in the participating schools were given a pocket booklet with phone numbers of local professional services which offer help on psychosocial, violence and substance abuse and other challenges. Any learner who specifically identified him or herself as in need of help during the study period was, with her consent, taken by teachers to a relevant local service, as per DBE standard practice. There was no financial re-imbursement for participating in the trial. The trial is registered on ClinicalTrials.gov as NCT02349321. The combined total school enrolment was 6076 of which 4095 (67.4%) obtained consent from the parents or caregivers to participate. Of the 4095, 3811 (93.1%) provided assent and participated in the trial. The percentage of learners in each school that did not complete the survey (incomplete surveys) ranged from 0.6% to 7.0% (mean 3.8%, SD 1.81).

Data collection

A survey was conducted using a self-administered questionnaire loaded in personal digital assistants (PDAs). The questionnaires were presented in English and two local languages spoken in the study area, SeTswana and SePedi. A participant could choose to use any of the three languages, either through text or voice to complete the questionnaire. Participants privately completed the survey in class and could ask for help from trained fieldworkers who oversaw the data collection process. After the survey, the data were uploaded to a secure server only accessible to the investigators and downloaded for cleaning and analysis [14, 15].

Conceptual model and measures

This paper presents an analysis from the baseline data from the Skhokho. The binary outcome is the learner’s experience of CP at school, derived from responses to one item: ‘In the past 6 months were you ever beaten by a teacher?’, with a ‘yes or no’ response.

Our hypothesized conceptual model looks at the inter-relationship between a learner’s home environment, mental health, attitude to schoolwork, learner behavior, and experience of CP at school. These factors are derived from several measures as summarized in Table 1. Our conceptual model is based on the hypothesis that a learner’s experience of CP at school is linked to their school environment (influenced by learner’s attitude and behavior at school, their perception of their teacher’s behavior and the attitude of their caregivers towards school work). The school environment is linked to home environment and mental health. The home environment is related to the family’s socio-economic status, therefore we derived a socio-economic status score using the learners’ parents/caregiver employment status, type of housing learner was living in, and amount of pocket money given to learner in a week (measured on an ordinal scale). We also hypothesized that learners’ negative experiences at home (physical punishment, neglect or poor communication with caregivers), their behavior (substance use, sexual behavior and misbehaviour, and their attitudes (towards schoolwork and towards teachers) were influenced by their age. Our hypothesized conceptual model is shown in Fig 1:

Table 1. Description of the factors that influence experience of corporal punishment at school.

Latent factor Measures Description of variables
Home Environment Male and female care-giver kindness/support An additive score from 7 items, measured on a 5-point likert scale (strongly agree (1), agree (2), disagree (3), strongly disagree (4), no caregiver (5)). Example item “My mother/ female caregiver does everything she can to support me.”
Caregiver-learner communication. An additive score from 4 items, measured on a 5-point scale (everyday, each week, at least once a month, sometimes but not each month, never). Example item “How often does one of your parents or caregivers ask how you are feeling or whether anything bothers you?”
Learner’s experience of physical punishment. An additive score of 3 items derived from the Child Trauma Questionnaire [32]. Example item “I have been punished at home by being beaten every day or every week” with responses as—in past 6m, between 6m and 12m, before the last 12m, never.
Learner’s experience of neglect in the home. An additive score of 2 items derived from the Child Trauma Questionnaire [32]. Example item “I have spent time outside the home and none of the adults at home knew where I was”, with responses as—in past 6m, between 6m and 12m, before the last 12m, never.
Learner’s behaviour Learner’s substance use (alcohol or drugs) An additive score from 2 item on learner’s alcohol use or drug use. Example item:
“How often do you usually drink alcohol?”, with responses as: every week, every month, less than once a month, less than once in a year, never.
Learner’s sexual behaviour An additive score derived from question on whether learner has ever dated, is having sexual relationships, is involved in transactional sex and the number of sexual partners ever had.
Misbehaviour An additive score derived from 5 items measured on a 4-point scale. Example item: “How often have you been involved in a fight with knives?”, with responses as: never, once, 2–3 times, more often.
School climate Care-giver’s attitude to learner’s school work One item measure on learner’s perception of care-giver attitude to schoolwork (My parents or care givers do not care how well I do at school), measure on a 4-point scale (Strongly agree-strongly disagree).
Learner’s perception of teachers’ behaviour An additive score of 7 items measuring the learner’s perception of teachers’ behavior, each item measured on a 4-point scale (strongly agree- strongly disagree). Example item: “Teachers are often late for class or miss lessons”.
Learner’s attitude to other learners and teachers (bullying) An additive score derived from 3 items on learner’s bullying attitude, each item measured on a 4-point scale. Example item: “I like to make life difficult for our teachers by doing what I feel like no matter what they say”

Data analysis

We used baseline data from the trial, and we applied data analytical procedures which took into account the school clustered sampling design and the cross-sectional nature of the baseline survey. This was an analysis of the baseline data from a cluster RCT design, with participants clustered within schools. We carried out descriptive analysis on all potential explanatory factors associated with learner’s experience of CP at school as described in our conceptual model. We used logistic regression to assess the relationship between experience of CP at school and all individual measures described in Table 1, and also assessed the correlation amongst the measures. We then assessed how the measures loaded unto our hypothesized latent constructs as defined in Table 1 and in Fig 1. We utilized various fit indices such as the (1) Comparative fit Index (CFI), (2) Tucker-Lewis Index (TLI), and Root Mean Square Error of Approximation (RMSEA), to assess how well the measurement model fitted to the observed data. For each factor, we allowed the variables to correlate freely and we also assessed the relationship between our outcome and each latent factor. All the 3 latent factors had high factor loadings and very good fit indices (CFI>0.95, TLI >0.95 and RMSEA<0.05). We then performed a Latent Path Analysis by applying general structural equation modelling techniques to assess the inter-relationships between the corporal punishment binary outcome, the latent constructs and other measured factors as hypothesized in our conceptual model.

The analyses were done separately for boys and girls and the final structural models are presented in Figs 2 & 3. The overall goodness of fit for the final models were good (for boys: CFI = 0.960, TLI = 0.930, RMSEA = 0.0434, for girls: CFI = 0.968, TLI = 0.938, RMSEA = 0.044). Due to having a combination of categorical and discrete measures in the models, we used weighted least squares mean and variance estimators (WLSMV) to estimate the simultaneous equations. The method handles missing data by using available data to estimate model parameters. Analyses were carried out in Mplus 8.6 software package (Muthen & Muthen, Los Angeles, CA 90066).

Results

The total number of learners enrolled in grade 8 in the 24 schools in 2014 when recruitment was done was 6076. A total of 4095 learners had parental consent to participate in the study, and 3811 gave learner assent, agreeing to participate. Of the 3811, 3743 completed the baseline survey: 2118 girls (56.6%) and 1625 boys (43.4%). Fourteen percent of boys and six percent of girls were 15 years and older. Most of the learners (69%) lived in a brick house and almost half (46%) lived with both biological parents. One in seven learners (14.5%) did not live with their biological parent. Forty-seven percent of the learners were living with an unemployed caregiver. More boys (47%) than girls (39%) belonged to a club or society. Most girls (90%) were actively involved in church compared to 85% of boys. Sixty percent of learners had ever dated, and six percent had used alcohol and drugs. Boys were more likely to have dated, to use alcohol or other substances (Table 2).

One in five learners (20.6%) had repeated a grade, and boys (28.1%) were more likely to have done so compared to girls (14.9%). Fifty-two percent of learners had experienced CP from teachers at school, and 44.8% from parents or caregivers at home in the last 6 months with levels of experience higher among boys compared to girls. More than half (60.5%) of boys had experienced CP at school and 48.3% at home, while 46.3% of girls experienced CP at school and 42.3% at home in the 6 months preceding the interview.

Table 3 shows the relationship between experiencing CP at school and individual measures of the different latent constructs. Experiencing CP at school was associated with all individual measures of learner behavior (substance use, sexual behavior, and misbehaviour), and with all individual measures of home environment (caregiver communication score, caregiver kindness score, corporal punishment score and learner’s neglect score), for both boys and girls. Less communication between caregiver and learner was associated with increased risk of experiencing corporal punishment. Caregiver unkindness was associated with increased risk of experiencing corporal punishment. Similarly, learners who experienced physical punishment at home were more likely to experience corporal punishment at school. Being neglected at home was associated with increased risk of experiencing corporal punishment at school. There were significant relationships between experiencing CP at school and individual measures of caregiver attitude to school work amongst girls. Caregiver’s negative attitude towards learner’s school work was associated with learner’s experience of corporal punishment at school. Caregiver’s attitude to school work was not associated with experiencing CP amongst boys. High household SES was associated with decreased risk of CP experience while depression was associated with increased risk of CP experience.

Fig 2 and Table 4 shows the pathways leading to boys’ experience of CP at school. The structural equation model shows a direct effect of family SES on the learner’s home environment, with low family SES status associated with negative home environment (β = -0.12, p-value<0.001). Low family SES status also has direct negative impact on a learner’s mental health (β = -0.07, p-value = 0.012). The home environment has direct impact on learner’s mental health (β = 0.35, p-value<0.001) and their behavior at school (to school work or towards educators or peers) (β = 0.28, p-value<0.001). The model also shows a significant impact of learner’s mental health on their general risky behavior (substance use, misbehaviour) (β = 0.15). For the boys, their misbehavior affects their relationship with their parents or caregivers at home (β = 0.52, p-value<0.001). As hypothesized, learner’s experience of CP at school is influenced mainly by their school environment (teacher behavior, learner’s behavior towards teacher’s and other learners, and parents or caregiver’s attitude towards schoolwork) (β = 0.28, p-value<0.001).

Fig 3 and Table 4 show the pathways leading to girls’ experience of CP at school. The pathways are similar to boys as was hypothesized but with some minor differences. For girls, despite showing negative impact of low family SES on mental health, this relationship was not significant. But consistent with boys, there was a strong relationship between home environment and learner’s mental health (β = 0.41, p-value<0.001), learner’s school climate (teacher behavior, learner’s behavior towards teachers and other learners, and parents or caregiver’s attitude towards schoolwork) (β = 0.25, p-value = 0.005), and their misbehavior (β = 0.56, p-value<0.001). Boys mental health has impact on their general misbehavior (substance use and general misbehaviour) (β = 0.15, p-value<0.001). As hypothesized and consistent with boys, girls’ experience of CP at school is influenced mainly by their school environment (teacher behavior, learner’s behavior towards teachers and other learners, and caregiver’s attitude towards schoolwork) (β = 0.34, p-value<0.001).

Discussion

This study aimed to describe the prevalence, factors associated with, and pathways to experiencing CP at school in the past six months. We found a high prevalence of CP experienced by learners at school, with more than half (52%) of the learners reporting CP experience in the past six months. The findings of this study highlight a slightly higher prevalence compared to that found in a national study (49.8%) conducted in 2012 [10], and confirm that CP of learners in public schools persists, despite it being outlawed over 20 years ago [13, 25]. Boys were more likely to experience CP at school compared to girls. This finding is consistent with findings of research from other countries which have shown gender differences in the experience of CP at school [16, 33]. Boys are perceived as naughty and mischievous compared to girls, which explains why they are more likely to experience CP [34, 35].

Our data has shown that the risk factors associated with learner experience of CP at school includes learner’s behaviour, home environment, school climate, and other factors including family’s SES and learner’s mental health. For learners, irrespective of gender, school environment (i.e. caregiver’s attitude towards school work, learner’s perception of teacher behaviour and learner bullying score) has a direct association with learner experience of CP. Learners’ negative perceptions towards teacher behaviour were associated with experiencing CP at school. Current evidence suggests that this relationship could go either direction. For example, some studies have shown that, for learners, having negative perceptions towards teacher behaviour increases the risk of experiencing CP at school, whereas others have shown that CP at school leads to learners’ negative perception towards teacher behaviour [36, 37]. The cross-sectional nature of the data analysed was a limitation to establishing temporality. However, our use of structural equation modelling enabled us to establish the pathways and inter-relationships of variables.

Even though in the bivariate analysis we found an association between sexual behaviour, substance use, bullying and CP at school; overall, no direct association was found between learner behaviour and CP at school in the multivariate analysis. For boys, learner behaviour had direct effects on home and school environment while among the girls, learner behaviour had direct effects on school environment only. School environment was the key factor associated with experience of CP for boys and girls, and this relationship was mediated by other factors including learner behavior and home environment. Addressing learner experience of CP at school requires that we not only focus on learner behaviour, but also on the home and school environments which have a direct association. As hypothesized, our data have shown that the home environment (exposure to physical violence, neglect and lack of caregiver kindness and support) has an indirect relationship with experience of CP at school, mediated by the school environment. Amongst girls, the home environment has a direct association with learner behaviour, which has an influence on the school environment, and experience of CP at school. This finding can be explained by the gender role expectations amongst girls compared to boys in some South African homes [38]. Some caregivers do not prioritize nor support education of girls who are mainly occupied by household chores in the home [39]. Young girls are socialised to clean, cook, take care of the children and to manage other household responsibilities in the home compared to boys [38, 40]. As such, most girls spend more time doing household chores than school-work when they are at home [39, 41]. Furthermore, the lack of caregiver support, and experience of neglect can contribute to misbehaviour which attracts CP at home and school. For many children, home life that is characterized by a parenting style which supports the use of CP as an effective method of managing behaviour is more likely to spillover to the school, with some parents or caregivers expecting teachers to use CP at school [4, 11, 13].

Studies have shown that boys are more likely to misbehave which results in intolerance and negative caregiver and teacher attitude towards them [42, 43]. With lack of support from both the parent or caregiver and the teacher, boys are more likely to perform poorly at school, with the poor performance attracting experience of CP [17, 44]. The association between lack of parental or caregiver involvement and poor academic performance in learners has been demonstrated in the literature [4547]. Experience of school CP amongst boys could be aimed at correcting their behaviour, based on the belief that physical punishment is effective in correcting deviant behaviour of children [4]. However, there is no consensus in the literature about the effectiveness of CP as a deterrent of misbehavior amongst learners. A study conducted in South African high schools in Soweto found that learners had become so insensitive to the physical pain inflicted through CP that their misbehavior was exacerbated rather than being curbed by it (Ngubane et al., 2019). The intolerance of boys’ misbehaviours could be emanating from caregivers’ and teachers’ limited capacity to manage misbehavior in children [48]. Corporal punishment could be the only corrective strategy familiar to caregivers at home, and teachers at school. As CP is illegal both in the home and at school in South Africa, programs for caregivers and teachers aimed to build capacity on using positive disciplining strategies are needed to end the use of CP [3, 49].

Furthermore, our findings have shown that the home environment was directly associated with learner’s mental health and learner behavior amongst girls. Learners who experience lack of care and support, and neglect at home are likely to experience poor mental health, which contributes to learner misbehaviour. Our study has shown that the influence of home environment and mental health also connects through family SES amongst boys. A gender effect of socio-economic status was also observed in other studies [50]. Interventions that address poor mental health are important for developmental wellbeing and academic performance of learners. A number of studies have highlighted the importance of caregiver involvement in improving both academic and mental health outcomes amongst adolescents [5153]. A positive family environment, and caregiver emotional support is associated with improved educational outcomes, social functioning and coping amongst adolescents [53, 54]. Adolescents with mental well-being possess problem-solving skills, social competence and a sense of purpose, which makes them resilient and more able to thrive in adverse circumstances [52].

The study had limitations in that the findings only represents the 24 schools included in the research, and cannot be generalized to other schools in Gauteng. Data used in this analysis formed part of the baseline assessment of the Skhokho RCT, thus other variables that are documented in the literature, and found to be associated with experience of CP such as neighbourhood and community level factors were not measured. Furthermore, the analysis was conducted from quantitative baseline data. A qualitative exploration of the topic might have provided further details about learner experiences of corporal punishment in schools. Given that use of CP is a behaviour of teachers, it is important to explore factors associated with teachers use of CP. Future qualitative research with learners and teachers is warranted to strengthen our understanding of not only the learners’ experience of CP but also teachers’ insights on why CP continues to be used at school, despite the legislation prohibiting its use.

Conclusion

Our findings have shown that learners still experience CP in public schools in South Africa. While there is a need to also focus on learner behaviour, our findings have highlighted the need to intervene in both the home and school environments. There is an urgent need to break this cycle of violence, through use of CP, by enforcing the law, and holding accountable those who continue to use CP despite legislation prohibiting its use, but also supporting the children in their home environment, and their parents to positively partner with their children. Furthermore, there is a need to provide services to meet leaner’s mental health needs. Evidence-based interventions are needed to support both parents and teachers in managing learner behaviour. Use of positive disciplining strategies, developing democratic relationship and consciousness about image of a child can positively informt how parents and teachers relate with children, critical for raising responsible children, and to curb future perpetration of violence in society [55, 56]. Effecting engrained beliefs, attitudes and behaviours supportive of corporal punishment amongst parents and teachers will require consistent education about the harms of corporal punishment and support for why it needs to be ended. Existing life skills curricula in schools need to be enhanced to assist learners with skills to deal with mental health issues and to build their resilience to withstand socio-economic hardships.

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Important note: This review pertains only to ‘statistical aspects’ of the study and so ‘clinical aspects’ [like medical importance, relevance of the study, ‘clinical significance and implication(s)’ of the whole study, etc.] are to be evaluated [should be assessed] separately/independently. Further please note that any ‘statistical review’ is generally done under the assumption that (such) study specific methodological [as well as execution] issues are perfectly taken care of by the investigator(s). This review is not an exception to that and so does not cover clinical aspects {however, seldom comments are made only if those issues are intimately / scientifically related & intermingle with ‘statistical aspects’ of the study}. Agreed that ‘statistical methods’ are used as just tools here, however, they are vital part of methodology [and so should be given due importance].

COMMENTS: Abstract-Methods section says “3743 grade 8 learners (2118 girls and 1625 boys) from 24 selected public schools in Tshwane, South Africa, enrolled in a cluster randomised controlled trial” my question is if the schools (clusters) are purposively selected, where is randomization? [according to lines 109-111, “All Grade 8 learners in 24 purposively selected English medium State secondary schools within a 50km radius from Pretoria City were eligible to participate in the study”].

Although, it is said in line 178 that [‘All data analysis procedures used took into account the study design’], it is not observed. In this context [authors may already know them, however, not found in the references of this manuscript], here are three good references.

Also note that

Though the measures/tools used are appropriate [Example - Line 112-3: A survey was conducted using a self-administered questionnaire loaded in personal digital assistants (PDAs)], most of them yield data that are in [at the most] ‘ordinal’ level of measurement [and not in ratio level of measurement for sure {as the score two times higher does not indicate presence of that parameter/phenomenon as double (for example, a Visual Analogue Scales VAS score or say ‘depression’ score)}]. Then application of suitable non-parametric test(s) is/are indicated/advisable [even if distribution may be ‘Gaussian’ (i.e. normal)]. Agreed that there is/are no non-parametric test(s)/technique(s) available to be used as alternative in all situation(s) [suitable / most desired/applicable], but should be used wherever/wherever they are available.

From Table 1 [Description of the factors that influence experience of corporal punishment at school] it appears that many measures used are of this type. I request the authors to also note that (this note is copied and pasted from a standard text book) : Whenever response options ranged from 1=strongly disagree to 4=strongly agree (or ranging from 1 (strongly disagree) to 6 (strongly agree) or from 1=very bad to 3=neither good nor bad to 5=very good), while using a ‘Likert’ scale responses, recoding [like strongly disagree=-2, disagree=-1, neutral=0, agree=1, strongly agree=2] may yield correct and meaningful ‘arithmetic mean’ which is useful not only for comparison but has absolute meaning, in my opinion. Application of any statistical test(s) assume that meaning of entity used (mean, SD, etc) has a particular meaning. Though ‘α’ [alpha] or most other measures of reliability/correlation will remain same, however. Use of non-parametric methods should/may be preferred while dealing with data yielded by any questionnaire/score.

From account given in lines 228-9 [Table 3 shows the relationship between experiencing CP at school and individual measures of the different latent constructs] it is clear that in table-3 {Bivariate relationship between corporal punishment experience score and a learner’s home environment, attitude and behavior measures.} first column Coef is ‘Correlation Coefficient’ (mostly Pearson’s) {LCL is lower & UCL is upper limit of CI I guess, why not given in footnote). Coefficient values are very small, yet most p-values show highly significant results. Is not that contradictory? In this context again it may please be noted that (following note is from a standard text book):

Statistical test usually used to assess significance of Pearson’s ‘Correlation coefficient (r)’ is ‘t’ [where t = { r � [(n-2) / (1-r2)] }for df=n-2, n is sample size] and here Ho is that the population/standard value of ‘r’ is zero. You need r=0.878 to be significant at 5% when n=5 but you need r=0.273 if n=50 & you need only r=0.088 if n=500. ‘P-value’ heavily depends on sample size. Therefore, it is customary to use the (available in most text books on ‘Biostatistics’ or on ‘www/net’) guidelines [very strongly suggesting to consider an absolute value of ‘Correlation coefficient’] for interpreting positive or negative correlations (and do not rely only on corresponding ‘P’-value but also consider an absolute value of ‘Correlation coefficient’). [This argument is equally applicable to non-parametric Spearman’s ‘Correlation coefficient (ρ)’ as well.]

Please look at an absolute value of ‘Correlation coefficient’ in table-3. It is suggested that ‘If r = +.70 or higher Very strong positive relationship’ or ‘-.70 or higher Very strong negative relationship’. In table-3, all ‘Coef’ are below 0.18 [smallest as small as 0.02]. It is not mentioned however that which type of correlation coefficient is used. But in case in the light of the above, interpretation given in lines 228 onwards is questionable.

Moreover, as said in lines 140-145 CP at school is measured by score [It is derived from 2 items: (i) ‘In the past 6 months were you ever beaten by a teacher?’, with a ‘yes or no’ response and (ii) “A teacher might beat you or physically punish you at our school” with responses as strongly disagree, disagree, agree and strongly agree. Our exploratory analysis showed that learners who agreed to statement (ii) were also likely to respond “yes’ to the first statement. We thus created a score from the 2 responses where high score represents higher likelihood of experiencing CP.] and both ‘simple linear regression’ as well as ‘correlation’ {lines 181-3: We used simple linear regression to assess the relationship between experience of CP at school and all individual measures described in Table 1, and also assessed the correlation amongst the measures} assume that (both ‘independent’ & ‘dependent’) variables are continuous.

Surprisingly use of ‘structural equation modelling’ seems to be correct. Account given in lines 184-198 seems perfectly alright. Figures 1,2,3 are alright. Look at the magnate of coefficients in contrast to coefficients reported/displayed in table-3, though they may be different [in nature & purpose].

Reviewer #2: This is an interesting quantitative study on the prevalence of corporal punishment amongst 8 graders in 24 selected government schools in South Africa. The study is trying to uncover the underlying reasons for its prevalence and suggests a solution to it.

The article is well-written and makes a good contribution to the field in that it provides evidence for the fact that corporal punishment is happening. This is in itself important as research in CP is notoriously difficult, because CP is illegal since 1997 and could cause major problems for teachers if found out. It is interesting that this part of the study is not really discussed at all. Research ethics and what exactly was said to the school principals is missing. For a study of this kind it is important to also publish the letters of consent and assent and how some of that was negotiated. CP tends to go underground when there is a risk that teachers might get reported. But there is another issue worth mentioning and that is, if corporal punishment is defined as physical punishment, then why are the main questions of the survey phrased in terms of ‘Were you beaten…?’. From my experiences of researching CP, beatings are a small part of the abuse that is routinely going on in schools. I would really like to see the full set of questions used in the study. The evidence sought was to identify the risk factors. There is interesting info about the characteristics of children who receive more CP in the literature, which is again confirmed by this study. A qualitative component probably would have given more unexpected results, because that is often ‘hiding’ in the details. I would very much like to have learned about teachers’ perspectives, but how to conduct such a study (and get indeed genuine information) is another matter. However, I understand such a follow-up study is in the pipeline.

The research was carried out by the SA Medical Research Council and it is within that context that some of my comments might be helpful. I am not an expert in quantitative studies and this one doesn’t use a qualitative component (although it recommends it as a follow-up study), so I can’t comment on the use of the methods that were used, but the following might be helpful:

1. Line 26: To my knowledge CP is not prevalent in schools globally, maybe homes? It would have been helpful to be more specific as it is certainly not common in schools in Europe, Australia etc, although it might be normal in households as parents are often allowed to use CP but not teachers. The details are important here.

2. Page 4: Factors that influence the use of CP in US are of use, but it would have been helpful to hear more about the racialised discourses that inform the use of CP - e.g. children are seen as wild and need to be tamed, domesticated and controlled. Innocence tends not to be attributed to brown bodies – a discourse also internalised by black people themselves. It was striking to see a lack of reference to racial, ethnic, religious and other such factors that are critical in relationships in SA. I would really like to see all research instruments included as Appendices.

3. At times it isn't clear to which part of the world the info applies and claims are made. For example, first there is evidence from Pakistan, then later US, but on page 5 it is unclear whether the authors make claims about CP as a global phenomenon or not. The info needs to be tied more specifically to the geopolitical location. What is missing is background information about the racialised and historically complex two-tier education system. Classrooms are very large and on the whole teachers not as qualified as in many other places. Therefore, this article could unfairly maybe give a very negative impression of a terribly underpaid and under supported workforce. Teachers in SA work under very difficult conditions and this article should include more information about teachers’ conditions so it doesn’t run the risk of being accused of a deficit approach, especially as teachers’ voice in the study is absent. It is only learners’ perspectives.

4. Line 90: This is a generalisation not supported by evidence. Education departments in SA Universities seem to be doing their upmost to teach their students alternative discipline strategies, but the phenomenon is more complex than that. Also Provincial education departments all have initiatives to support teachers in using different discipline methods, but the particular image of child and childhood and child/adult relations tend to be hierarchical in SA and lack the equality needed for respectful non-violent relations. This is typical of patriarchal societies. The violence against children in SA is intricately connected to the violence against women.

5. What is completely missing is the relationship between the training of teachers, their ability to teach in ways that engages learners and motivates them. Teacher educators know that e.g. more active and embodied pedagogies can be used that prevent 'misbehaviour' from occurring. Large class sizes etc also really contribute to CP and not having classroom assistants.

6. The intervention focuses on positive discipline and psychological interventions, but not on the image of the child or the pedagogical dimensions. So in a sense, the hypothesis of the study makes sense in the light of the identity of the researchers. It would be helpful to include in future research someone from a very different educational background so base-line hypotheses can be enriched. We know from educational research that teachers tend to teach how they were taught and it is very difficult to break through that despite the many interventions in teacher education and by provincial departments. Therefore, the suggestion that the solution to the problem identified might be to offer training in positive discipline is nothing new and has been going on for some time now. It is a good idea to check out this literature. What would be worthwhile and unusual and new instead is to include an in-service course/intervention in childhood studies (to teach about the image of the child) and the building of democratic relationships through e.g. ‘shared authority’ models. These are about more sustainable and durable changes as they could affect deeply engrained beliefs about children as found wanting (by adults), rather than interventions that don’t change fundamental beliefs about people and their relations. However, this would require pedagogical skills and working with both groups at the same time: learners and their teachers.

In short, this is a very informative article, well written and researched and helpful in that it confirms much of what we already know about CP, and indeed helpful for funding purposes, but it misses the important geopolitical educational dimension (which still can be added) and references to pedagogies which hopefully can be taken into account in further studies. I hope the above comments are helpful, in order to add further reflections to the current paper, but especially I hope they are useful for future research purposes.

Reviewer #3: This study examines the prevalence and factors associated with corporal punishment in public schools in South Africa using baseline data from a larger RCT study.

This is a highly competent and well published team who have completed most of the seminal work on interpersonal violence in South Africa and in fact globally

The methodology of the larger randomized controlled trial is excellent and it appears to be a well conducted study

I have one analytic concern. The authors merge two questions ‘In the past 6 months were you ever beaten by a teacher?’ and “A teacher might beat you or physically punish you at our school”. These are two entirely different questions and simply because most people answer yes to the first have answered yes to the second (of course they have) is no reason to merge them. This must be corrected in the revised version.

The use of the term ‘delinquent’ is highly problematic, certainly not justified by the data collected in the paper and should be deleted. To describe a learner as delinquent based on 5 questions is highly problematic.

A more general concern has to do with what these findings add to the literature. Corporal punishment is associated with learner behaviour, home environment and school environment (i.e. everything). It does feel a little like squeezing another paper out of the dataset. While the paper adds little to what is already known, the method and execution of the study are of a high standard and the findings may be of some interest to education authorities in South Africa.

Dear Editor

Thank you for the opportunity to revise our paper. Below we have described how we have responded to the comments from the reviewers

Best regards,

Reviewer 1

Important note: This review pertains only to ‘statistical aspects’ of the study and so ‘clinical aspects’ [like medical importance, relevance of the study, ‘clinical significance and implication(s)’ of the whole study, etc.] are to be evaluated [should be assessed] separately/independently. Further please note that any ‘statistical review’ is generally done under the assumption that (such) study specific methodological [as well as execution] issues are perfectly taken care of by the investigator(s).

Agreed that ‘statistical methods’ are used as just tools here, however, they are vital part of methodology [and so should be given due importance].

Thank you very much for your time reviewing our manuscript and for the valuable feedback. We have revised and clarified the analytic methods applied to address issues raised, taking into account suggestions and recommendations from all the reviewers.

Abstract-Methods section says “3743 grade 8 learners (2118 girls and 1625 boys) from 24 selected public schools in Tshwane, South Africa, enrolled in a cluster randomised controlled trial” my question is if the schools (clusters) are purposively selected, where is randomization? [according to lines 109-111, “All Grade 8 learners in 24 purposively selected English medium State secondary schools within a 50km radius from Pretoria City were eligible to participate in the study”].

While selection of the schools into the study was not random, the allocation of the selected schools to the interventions arms was random.

Although, it is said in line 178 that [‘All data analysis procedures used took into account the study design’], it is not observed. In this context [authors may already know them, however, not found in the references of this manuscript], here are three good references.

3. Kerry SM & Bland JM. ‘Analysis of a trial randomized in clusters’ by in British Medical Journal, Volume 316, 1998, p54.

We acknowledge the source of information provided on analysis of cluster randomized. In our analysis, we performed individual level analysis considering:

i) We are analyzing baseline data for an outcome that is not primary trial outcome.

ii) We have a sizable number of clusters per arm and we accounted for the clustering

in the estimation of standard errors in all the models.

Though the measures/tools used are appropriate [Example - Line 112-3: A survey was conducted using a self-administered questionnaire loaded in personal digital assistants (PDAs)], most of them yield data that are in [at the most] ‘ordinal’ level of measurement [and not in ratio level of measurement for sure {as the score two times higher does not indicate presence of that parameter/phenomenon as double (for example, a Visual Analogue Scales VAS score or say ‘depression’ score)].

But in case in the light of the above, interpretation given in lines 228 onwards is questionable.

We acknowledge the concern raised regards the distributional assumptions for the analytical methods used in the bivariate analysis. We do agree that non-parametric tests are more robust than parametric test for discrete measures.

Our aim for performing the correlations/linear regression analyses was mainly as an exploratory data analysis preceding the main analysis (structural equation model). This was done to show how the different measures were associated with the outcome (experience of corporal punishment), prior to the SEM analysis.

Based on recommendation from the review, we have defined our outcome measure (corporal punishment experience) as a binary outcome derived from responses from 1 question rather than from 2 questions as previously defined.

We have thus revised Table 3 to reflect this change and we now present relationships using Odds ratios from logistic regression models.

We have revised Tables

Moreover, as said in lines 140-145 CP at school is measured by score [It is derived from 2 items: (i) ‘In the past 6 months were you ever beaten by a teacher?’, with a ‘yes or no’ response and (ii) “A teacher might beat you or physically punish you at our school” with responses as strongly disagree, disagree, agree and strongly agree. Our exploratory analysis showed that learners who agreed to statement (ii) were also likely to respond “yes’ to the first statement. We thus created a score from the 2 responses where high score represents higher likelihood of experiencing CP.] and both ‘simple linear regression’ as well as ‘correlation’ {lines 181-3: We used simple linear regression to assess the relationship between experience of CP at school and all individual measures described in Table 1, and also assessed the correlation amongst the measures} assume that (both ‘independent’ & ‘dependent’) variables are continuous.

As indicated above, we have redefined the outcome using only 1 item (In the past 6 months were you ever beaten by a teacher?)

Surprisingly use of ‘structural equation modelling’ seems to be correct. Account given in lines 184-198 seems perfectly alright. Figures 1,2,3 are alright. Look at the magnate of coefficients in contrast to coefficients reported/displayed in table-3, though they may be different [in nature & purpose]. Thank you. We have revised the SEM analysis and fitted a Generalised SEM with the experience of corporal punishment defined as a binary outcome.

Reviewer #2

This is an interesting quantitative study on the prevalence of corporal punishment amongst 8 graders in 24 selected government schools in South Africa. The study is trying to uncover the underlying reasons for its prevalence and suggests a solution to it.

Thank you very much for your time reviewing our manuscript and for the valuable feedback.

The article is well-written and makes a good contribution to the field in that it provides evidence for the fact that corporal punishment is happening. This is in itself important as research in CP is notoriously difficult, because CP is illegal since 1997 and could cause major problems for teachers if found out.

A qualitative component probably would have given more unexpected results, because that is often ‘hiding’ in the details. I would very much like to have learned about teachers’ perspectives, but how to conduct such a study (and get indeed genuine information) is another matter. However, I understand such a follow-up study is in the pipeline. a. The use of corporal punishment in schools is prohibited by law in South Africa. Any person who administers corporal punishment at school is guilty of an offence and liable on conviction to a sentence which could be imposed for assault. This has been added in the introduction section on page:

The South African Schools Act No 84 of 1996 states that no person may administer CP to a learner at school (1). Any person who administers corporal punishment at school is guilty of an offence and liable on conviction to a sentence which could be imposed for assault (1).

b. We have added on page 9 line 138 a sub-heading ‘Ethical considerations. We have also added a paragraph in line 141 – 148 explaining what was said to principals when requesting permission to work in schools:

Permission was also granted by the school principals in the 24 schools. The information letter detailing the nature and purpose of the study, the interventions, participants, what the project would offer to schools, risks and benefits of participating in the study, project timelines, and on rights of participants was provided to principals. School principals were also informed that all data generated from the study will be kept confidential and that research reports and articles which will be submitted in scientific journals will not include any information that may identify the school or any of the educators, learners, school governing body officials and parents.

c. We agree with the reviewer that CP tends to go underground, underreported when there is a risk that teachers might get reported. This is also shown in studies where both learners and teachers have been involved and the findings showed varied reports of use of corporal punishment in schools, learners reporting higher prevalence that teachers. In our study, use of corporal punishment in the 24 schools was reported by learners

d. Table 1 describes the main aspects of the questionnaire

e. We used the Childhood Trauma Questionnaire and cognitively tested the questionnaire amongst grade 8 learners in schools which were not part of the research and found that ‘beaten’ was understood and captured corporal punishment as was intended

f. We have expanded the limitations section on page 27, line 439 - 445 to acknowledge the limitation of not including a qualitative component and teacher’s perspectives:

Furthermore, the analysis was conducted from quantitative baseline data. A qualitative exploration of the topic might have provided further details about learner experiences of corporal punishment in schools. Given that use of CP is a behaviour of teachers, it is important to explore factors associated with teachers use of CP. Future qualitative research with learners and teachers is warranted to strengthen our understanding of not only the learners’ experience of CP but also teachers’ insights on why CP continues to be used at school, despite the legislation prohibiting its use.

The research was carried out by the SA Medical Research Council and it is within that context that some of my comments might be helpful. I am not an expert in quantitative studies and this one doesn’t use a qualitative component (although it recommends it as a follow-up study), so I can’t comment on the use of the methods that were used, but the following might be helpful:

Thank you very much for your time reviewing our manuscript and for the valuable feedback

1. Line 26: To my knowledge CP is not prevalent in schools globally, maybe homes? It would have been helpful to be more specific as it is certainly not common in schools in Europe, Australia etc, although it might be normal in households as parents are often allowed to use CP but not teachers. The details are important here.

While use of corporal punishment in school is banned and no longer an issue in European countries, it is a problem that requires attention in many other parts of the world. Corporal punishment is still prevalent in a third of the world’s countries where it continues to be used as a method of disciplining children, both in countries where it is legal and countries where it is banned, leading to estimates that millions of children are subject to this harmful practice (2, 3).

We have revised the introduction section to become more specific about prevalence of CP globally, line 25 – 31:

While the use of a physical methods of discipline, also referred to as corporal punishment (CP) at school is banned and no longer an issue in European countries; it continues to be prevalent in a third of the world’s countries, despite evidence regarding its harmful physical, mental and behavioural effects on the child (1, 2). The global prevalence of CP in schools ranges between 13% – 97% of learners who reported experience of CP at school (1). Learners continue to experience CP in most countries in Sub-Saharan Africa despite legislation prohibiting its use (1, 2).

2. Page 4: Factors that influence the use of CP in US are of use, but it would have been helpful to hear more about the racialised discourses that inform the use of CP - e.g. children are seen as wild and need to be tamed, domesticated and controlled. Innocence tends not to be attributed to brown bodies – a discourse also internalised by black people themselves. It was striking to see a lack of reference to racial, ethnic, religious and other such factors that are critical in relationships in SA. I would really like to see all research instruments included as Appendices.

We agree with the reviewer that race, ethnicity and religion are critical in relationships in South Africa. However, unlike in American schools, most public schools in South Africa are still very much racially segregated by communities served in that area. While the system of schools divided by race was eliminated in 1996s, public schools in Black townships or communities are racially homogenous, while the historically White and Indian schools serve a more racially diverse constituency (5, 6).

About 21 of the schools where this research was conducted were black only schools: Only three of the 24 schools were mixed race schools. Even in the three mixed race schools, more than 90% of the students were black and this is shown in Table 2 on page 16

The reviewer is correct about the diversity in religion and ethnicity in schools in South Africa, recognized in the National Policy on Religion and Education of 2003. It is possible that religion and ethnicity could have been amongst the factors associated with learner experience of corporal punishment in schools, but we did not include in our analysis.

3. At times it isn't clear to which part of the world the info applies and claims are made. For example, first there is evidence from Pakistan, then later US, but on page 5 it is unclear whether the authors make claims about CP as a global phenomenon or not. The info needs to be tied more specifically to the geopolitical location. What is missing is background information about the racialised and historically complex two-tier education system. Classrooms are very large and on the whole teachers not as qualified as in many other places. Therefore, this article could unfairly maybe give a very negative impression of a terribly underpaid and under supported workforce. Teachers in SA work under very difficult conditions and this article should include more information about teachers’ conditions so it doesn’t run the risk of being accused of a deficit approach, especially as teachers’ voice in the study is absent. It is only learners’ perspectives.

We have revised the introduction to include background information about the racialized and historically complex two-tier education system in South Africa in line 34 - 38:

Corporal punishment has been an integral part of schooling for most teachers and learners in twentieth century South African schools, characterized by a legacy of authoritarian education practices under Bantu education and a belief that CP is necessary for orderly education (7). The ending of apartheid and the establishment of a human rights culture in the 1990s laid the foundation for legislation aimed at ending use of CP in schools in South Africa (7).

Line 40 – 44:

South Africa is a highly inequitable society and this inequality is reflected in the historically complex two-tier education system namely, the middle class, private schools and the public schools (5). The middle class, formerly white schools no longer use corporal punishment as a discipline method (7). However, in public schools, use of corporal punishment is still common practice (8, 9)

We agree with the reviewer that teachers, particularly in public schools, work under difficult conditions and this background information has now been added in line 44 – 47:

In most public schools, classrooms are overcrowded and under-resourced, and teachers are often under-qualified and overworked (10, 11). Teachers feel disempowered and ill-equipped with viable alternative discipline methods to maintain a safe and secure environment to facilitate learning (8)

4. Line 90: This is a generalisation not supported by evidence. Education departments in SA Universities seem to be doing their upmost to teach their students alternative discipline strategies, but the phenomenon is more complex than that. Also Provincial education departments all have initiatives to support teachers in using different discipline methods, but the particular image of child and childhood and child/adult relations tend to be hierarchical in SA and lack the equality needed for respectful non-violent relations. This is typical of patriarchal societies. The violence against children in SA is intricately connected to the violence against women.

We have revised the paragraph. It now reads as follows in line 109 - 112:

While use of CP is illegal in South Africa, there has been limited concerted effort to enforce the law, ensuring that those who continue to use CP are convicted of an offense, and inadequate training of teachers on alternative methods of classroom management and discipline (30, 31)

More can be done to enforce implementation of legislation and holding accountable those who illegally continue to use CP despite legislation prohibiting its use. Gershoff points that: legal bans are not sufficient to completely eliminate school corporal punishment. Behavior change by teachers and school administrators is what is needed. Behaviour change will require consistent education about the harms of corporal punishment and about alternative, positive forms of discipline. While there might be pockets of schools where teachers are exposed to initiatives aimed to use positive discipline methods, not all schools have been provided with such, and the support has not been consistent. We have revised the conclusion, line 453 – 455:

There is an urgent need to break this cycle by enforcing the law, and holding accountable those who continue to use CP despite legislation prohibiting its use

And line 459 – 464:

Use of positive disciplining strategies, developing democratic relationship and consciousness about image of a child will direct how parents and teachers relate with children, critical for raising responsible children, and to curb future perpetration of violence in society (55, 56) Effecting engrained beliefs, attitudes and behaviours supportive of corporal punishment amongst parents and teachers will require consistent education about the harms of corporal punishment and support for why it needs to be ended.

5. What is completely missing is the relationship between the training of teachers, their ability to teach in ways that engages learners and motivates them. Teacher educators know that e.g. more active and embodied pedagogies can be used that prevent 'misbehaviour' from occurring. Large class sizes etc also really contribute to CP and not having classroom assistants.

We agree with the reviewer that there are many factors that could explain use of corporal punishment amongst teachers including factors related to their training. It is likely that these factors are contributing to their ability/ inability to teach in ways that engages the learner and motivates them, so as to manage some of the risk factors associated with learner experience of CP. As suggested by the reviewer, a study which captures teacher’s perspectives on use of corporal punishment in schools will contribute to knowledge and respond to these questions. We have not included teachers’ perspectives on this paper, and plan to do so in future.

6. The intervention focuses on positive discipline and psychological interventions, but not on the image of the child or the pedagogical dimensions. So in a sense, the hypothesis of the study makes sense in the light of the identity of the researchers. It would be helpful to include in future research someone from a very different educational background so base-line hypotheses can be enriched. We know from educational research that teachers tend to teach how they were taught and it is very difficult to break through that despite the many interventions in teacher education and by provincial departments. Therefore, the suggestion that the solution to the problem identified might be to offer training in positive discipline is nothing new and has been going on for some time now. It is a good idea to check out this literature. What would be worthwhile and unusual and new instead is to include an in-service course/intervention in childhood studies (to teach about the image of the child) and the building of democratic relationships through e.g. ‘shared authority’ models. These are about more sustainable and durable changes as they could affect deeply engrained beliefs about children as found wanting (by adults), rather than interventions that don’t change fundamental beliefs about people and their relations. However, this would require pedagogical skills and working with both groups at the same time: learners and their teachers.

We thank the reviewer for this comment, which we have noted. We will ensure that in future we involve someone with education background to help enrich our work by incorporating a focus on the image of the child or the pedagogical dimensions.

We have incorporated the reviewer’s suggestions on strategies to address corporal punishment in schools, line 459 – 464:

Use of positive disciplining strategies, developing democratic relationship and consciousness about image of a child will direct how parents and teachers relate with children, critical for raising responsible children, and to curb future perpetration of violence in society (55, 56) Effecting engrained beliefs, attitudes and behaviours supportive of corporal punishment amongst parents and teachers will require consistent education about the harms of corporal punishment and support for why it needs to be ended.

In short, this is a very informative article, well written and researched and helpful in that it confirms much of what we already know about CP, and indeed helpful for funding purposes, but it misses the important geopolitical educational dimension (which still can be added) and references to pedagogies which hopefully can be taken into account in further studies. I hope the above comments are helpful, in order to add further reflections to the current paper, but especially I hope they are useful for future research purposes. We have revised the paper and included recommendations on teaching practices that are critical in efforts to end use of corporal punishment in schools, line 459 – 464:

Use of positive disciplining strategies, developing democratic relationship and consciousness about image of a child will direct how parents and teachers relate with children, critical for raising responsible children, and to curb future perpetration of violence in society (55, 56) Effecting engrained beliefs, attitudes and behaviours supportive of corporal punishment amongst parents and teachers will require consistent education about the harms of corporal punishment and support for why it needs to be ended.

Reviewer 3

This study examines the prevalence and factors associated with corporal punishment in public schools in South Africa using baseline data from a larger RCT study.

This is a highly competent and well published team who have completed most of the seminal work on interpersonal violence in South Africa and in fact globally

The methodology of the larger randomized controlled trial is excellent and it appears to be a well conducted study Thank you very much for your time reviewing our manuscript and for the valuable feedback.

I have one analytic concern. The authors merge two questions ‘In the past 6 months were you ever beaten by a teacher?’ and “A teacher might beat you or physically punish you at our school”. These are two entirely different questions and simply because most people answer yes to the first have answered yes to the second (of course they have) is no reason to merge them. This must be corrected in the revised version.

Thank you for highlighting this point. We have corrected this. We have redefined the outcome using only 1 item (In the past 6 months were you ever beaten by a teacher?)

The use of the term ‘delinquent’ is highly problematic, certainly not justified by the data collected in the paper and should be deleted. To describe a learner as delinquent based on 5 questions is highly problematic. We have replaced the term delinquent with misbehaviour throughout the manuscript

A more general concern has to do with what these findings add to the literature. Corporal punishment is associated with learner behaviour, home environment and school environment (i.e. everything). It does feel a little like squeezing another paper out of the dataset. While the paper adds little to what is already known, the method and execution of the study are of a high standard and the findings may be of some interest to education authorities in South Africa. The revisions based on the comments from the reviewers have improved the paper.

While a lot has been written about corporal punishment in schools, very few published papers discuss the prevalence and use SEM to describe the interrelationships between factors associated with learner experience of CP in schools in South Africa. Like in other countries, South African schools are contextually unique, and deserving to be studied so we can have a better understanding of factors associated with use of CP in schools in South Africa. Given that CP is prohibited, yet continues to be used says that there is a problem, which needs to be engaged with, and recommended made on how it can be addressed.

As such, this paper contributes to literature on the prevalence and factors associated with learners experiences of corporal punishment in schools in South Africa, and makes recommendation on what can be done to curb the use of corporal punishment in schools.

Reviewer #1: COMMENTS: Most of the comments made on earlier draft {by me and hopefully by other respected reviewers also) were/are attended adequately. The manuscript is improved a lot. May be accepted if found clinically relevant.

Reviewer #2: Thank you for addressing my concerns quite meticulously. One of my key concerns does remain though and that is the narrow way in which CP has been defined in the study. Of course that can no longer be retified as it has been asumed from the outset and informed tha data collection. Corporal punishment is broader than 'being beaten'. Research has thrown up how much pain and physical discomfort is caused without beating a child. This can be by letting children stand for hours in a hot sun with their hands above their heads and without water or let them stand in a particular position against the wall for a long time so their legs will start to hurt. There are many ways in which children are hurt daily without being beaten. That is also corporal punishment. See eg the following link for the compexity in defining CP. This needs to be better explored and addressed in future studies. https://www.un.org/development/desa/family/wp-content/uploads/sites/23/2020/06/Freer_Expert-Group-Paper_Corporal-Punishment-Physical-Abuse_June2020.pdf
