Abstract

The Coronavirus Anxiety Scale (CAS) is among the first few published screening tools for assessing dysfunctional anxiety induced by the current COVID-19 pandemic. The CAS was translated into the Bangla language following the International Test Commission’s guidelines for this adaptation study and placed in an online survey (N = 737, with a mean age of 26.55 (SD = 7.166 years) to assess the psychometric properties of the Bangla version of the scale. Results suggested that all items had a good item discrimination index and single-factor structure with good factor loadings. The CAS Bangla version was found to have good internal consistency reliabilities, test-retest reliability, and composite reliability (≥ 0.7). The measurement invariance suggested invariances across age groups and gender. The CAS Bangla version showed a high correlation to the anxiety subscale of the short form of the Depression Anxiety Stress Scale (DASS-21) and a moderate correlation to the depression subscale of the DASS-21 and the COVID-19 Worry Scale. This validation of a Bangla CAS scale would be helpful for mental health practitioners to assess pandemic anxiety among the Bangladeshi people.

Background

The world is amid a global pandemic, causing instability in every area of human life. The situation is a genuinely frightening and daunting time for many. The discovery of the epidemic was first proclaimed on the last day of 2019 in Wuhan, China (World Health Organization 2020). In the months since, SARS-CoV-2 or COVID-19 is now the third deadliest pandemic to have faced the twenty-first century (Washington Post 2020; Worldometer 2020a, May 22). At this point, the rate of infection growth, causality, and recuperation is unknown (Sharma et al. 2020). So far, the novel virus has infected over five million (5,199,016) people globally (Worldometer 2020b, May 22). The death rate of COVID-19 is rising fast across the world, driving many to become desperate for a solution. In addition, the unpredictability of the virus’ nature creates an environment of ongoing stress, which can increase the risks of people developing psychological disorders (Zandifar and Badrfam 2020). These psychological aspects must be addressed as the mental strain will likely continue following the pandemic, as people will continue to grieve the deaths of those who they lost to the novel virus (Taylor and Asmundson 2020).

Moreover, in order to reduce the rapid spread of the virus, all affected countries have imposed full or partial lockdowns and instituted a range of practices (e.g., “social isolation,” “self-isolation,” “spatial distancing,” “quarantine,” etc.) to prevent people from gathering in large numbers. Although these first-line emergency responses are designed to reduce the spread of the infectious disease, many people who are quarantined may develop feelings of loneliness, boredom, physical inactivity, and insecurities about food and finances (Brooks et al. 2020; Kamal 2020; Seppo 2020). Although these routines are designed to limit people’s exposure to the deadly virus, they can also induce fear and anxiety about infection for those who partake in these new practices (McKay et al. 2020). Recent studies on the psychological effects during the COVID-19 pandemic have suggested higher than usual rates of anxiety and depression in the population (Ahmed et al. 2020a; Wang et al. 2020). According to the Anxiety and Depression Association of America (ADAA 2020), the current outbreak of the coronavirus has caused increased anxiety levels among many in the public community. Recent studies have supported this claim, showing that fear and anxiety about COVID-19 are associated with higher anxiety and depression symptoms (Ahorsu et al. 2020; Lee et al. 2020). Given the importance of identifying coronavirus anxiety in the population, because of its negative influence on people’s mental health and well-being during the pandemic, it is imperative that health professionals and researchers screen people for this condition. However, to date, there are no known instruments to assess dysfunctional coronavirus anxiety in Bangladesh. Thus, the purpose of this study is to validate the Coronavirus Anxiety Scale (CAS; Lee 2020a) as a clinical mental health screener in the Bangla language.

Present Study

At the time of writing, 30,205 people have tested positive for COVID-19, and 432 have died by the virus in Bangladesh (Institute of Epidemiology Disease Control and Research 2020, May 22). For the country, the number of positive cases and deaths are both still increasing. As a first-line emergency response to the COVID-19 outbreak, the Bangladesh government announced general leave and a shutdown of all offices, markets, transports, etc., except for emergency services, since March 26, 2020 (WION News 2020). Since shutdowns, Bangladeshi people have been isolated and living with fear and uncertainty over this prolonged period (Nooruddin and Shahid 2020). That aside, many are suffering from the psychological effects of this situation across the globe (Limcaoco et al. 2020; Wang et al. 2020); Bangladesh is no exception to that—seeing its first COVID-19 suicide case as a result of coronavirus fears (Mamun and Griffiths 2020). Therefore, it is vital that the Bangladeshi people who appear to be mentally affected be efficiently and effectively screened for psychological services as soon as possible. Thus, the present study aims to translate the CAS into the Bangla language so that its adaption can be used for the assessment of dysfunctional anxiety, due to the COVID-19 outbreak, for Bangladeshi people.

Method

Participants

An online survey was conducted to collect data using a survey link created on a Google Form. It was then distributed via email and social media like Facebook, WhatsApp, etc. The only inclusion criterion to participate in this study was that participants had to be at least 18 years old. A total of 737 people completed the online survey; among them, eight were excluded as they are below 18 years. The remaining participants’ ages ranged from 18 to 99 years (M = 26.55, SD = 7.166). Among the 729 participants, 60.6% were male, 39.4% were female, 2.6% completed secondary education, 14.7% completed higher secondary school, 46.5% had an undergraduate degree, and 35.8% had post-graduate degrees. Among them, 64.5% were living in urban areas, 15% in semi-urban areas, and 20.6% were in rural areas. In terms of employment status, 60.4% were students, 29.9% were full-time employees, 4.4% in business or self-employed, 3.3% in other jobs, and 2.4% were unemployed.

Ethics

The present study was conducted following the Declaration of Helsinki and its later amendments or comparable ethical standard. Additionally, the study received ethical approval, before the study was undertaken, from the Noakhali Science and Technology University (reference no. 21/2020). Study objectives, potential benefits, risks, the confidentiality of given responses, etc. were communicated with participants in an informed consent form, prior to starting the survey. After reading the form, participants gave their consent to participate by clicking either “I agree to participate” or “I don’t agree to participate.” Only after clicking on “I agree to participate” was a participant able to take part in the survey.

Measures

The online survey included the CAS (Lee 2020a), the COVID-19 Worry Scale (CWS; Ahmed et al. 2020b), the anxiety and depression subscales of a short form of the Depression Anxiety Stress Scale (DASS-21; Lovibond and Lovibond 1995; Alim et al. 2014 [Bangla version]), the brief Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS; Stewart-Brown et al. 2009; Rahman and Imran 2013 [Bangla version]), and demographic information including gender, age, residence status, education level, and employment status.

Coronavirus Anxiety Scale

The CAS (Lee 2020a) is a valid unidimensional tool that assesses the physiological reactions of fear and anxiety related to the COVID-19 pandemic. This dysfunctional coronavirus anxiety scale consists of 5 items (e.g., “I lost interest in eating when I thought about or was exposed to information about the coronavirus”). In addition, it has excellent internal consistency reliability, construct, and concurrent validity. For the scale, participants were asked to rate the items on a 5-point Likert-type scale, from 0 (not at all) to 4 (nearly every day over the last 2 weeks). The cutoff score for this scale is ≥ 9, with 90% sensitivity and 85% specificity.

In the present study, the CAS was translated into Bangla following the guidelines of the International Test Commission (International Test Commission 2018) for the translation and adaptation of measurement instruments from one language to another language. At first, the CAS was translated into Bangla from English independently by two bilingual experts, and then, these two versions were synthesized into one. Next stage, the Bangla version of the CAS was back-translated into English by two other bilingual experts and then combined into one. The original English and back-translated versions were compared with check whether the meaning of any item differed. There was no significant difference in meaning between the original and back-translated versions. In the next stage, the translated CAS was put into a pilot study (n = 22, 54.5% female, mean age = 23.55 (SD = 1.30) years, and COVID-19 anxiety M = 3.32, SD = 2.97) where a cognitive interview was taken. Results suggested that all participants understood all items of this version of the CAS clearly. Having no problems in the pilot study, the translated CAS was placed into a final test for assessing its psychometric properties. For the present study, the CAS Bangla version demonstrated good internal consistency (ω = 0.879, α = 0.872).

COVID-19 Worry Scale

The CWS (Ahmed et al. 2020b) is a valid unidimensional tool for assessing worries related to the COVID-19 infection. This scale consists of 7 items (e.g., “How concerned are you about being affected by the Coronavirus?”) that assess the concerns about self, family members, relatives, etc. being affected by COVID-19. Authors have reported that the CWS has good internal consistency reliabilities (0.81 to 0.85), construct (factor loadings ranging from 0.70 to 0.83), and convergent validity. The CWS scores significantly correlated with stress, anxiety, and depression scores of the DASS-21. Participants were asked to rate each item using a 4-point Likert-type scale, from 1 (not at all) to 4 (very much). Total scores could range from 7 to 28. For this scale, respondents who scored 23 or above are considered highly worried. In the present study, the CWS showed good internal consistency (ω = .881, α = .875).

Short Depression Anxiety Stress Scale

The Depression Anxiety Stress Scale (DASS; Lovibond and Lovibond 1995) is a valid tool for quick assessment of depression, anxiety, and stress. This scale has 42 items with 14 items per subscale. Participants were asked to rate their responses based on their experiences from the previous week. Items were rated on a 4-point Likert-type scale, from 0 (did not apply to me at all) to 3 (applied to me very much or most of the time). Total scores could range from 0 to 42 for each subscale. The DASS has good internal consistency reliability and construct and concurrent validity. The shorter version of the DASS includes 21 items, with 7 items in each subscale. Antony et al. (1998) suggest using the DASS-21 since it has similar psychometric properties to the longer DASS-42. When scoring the DASS-21, the sum of the 7 items in each subscale needs to be multiplied by 2 to get a total score. The DASS-21 Bangla version (Alim et al. 2014) also has good psychometric properties for quick assessment of stress, anxiety, and depression among Bangladeshi people. For this study, the depression and anxiety subscales of the DASS-21 were used, and both subscales showed good internal consistency reliabilities (ω = 0.874, α = 0.872 and ω = 0.804, α = 0.899, respectively).

Short Warwick-Edinburgh Mental Wellbeing Scale

The Warwick Edinburgh Mental Wellbeing Scale (WEMWBS; Tennant et al. 2007) is a 14-item quick measure for assessing mental well-being among the general population. This scale along with the Bangla version (Rahman and Imran 2013) has good reliabilities and construct and concurrent validities. For the scale, participants were asked to rate their responses from their feelings over the past week. They were rated on a 5-point Likert-type scale, from 1 (none of the time) to 5 (all the time)—with total scores ranging from 14 to 70. Using Rasch modeling, Stewart-Brown et al. (2009) suggest using the shorter version of the scale (SWEMWBS), consisting of only 7 items. Thus, for this study, we used the SWEMWBS as it showed superior interval scaling than the full-length scale. This shorter scale also showed good internal consistency reliability (ω = .876, α = .874).

Data Analysis

The use of descriptive statistics (frequency, percentages, mean, and standard deviation) was used to assess the participants’ characteristics from the study. Psychometric properties of the CAS Bangla were assessed using the classical test theory (CTT). Under the CTT, we assessed corrected item-total correlation (minimum of .30; Field 2017), internal consistency reliabilities (Cronbach’s alpha, McDonald’s omega, and using the Spearman-Brown formula; accepted value ≥ 0.70), standard error of measurement (accepted value < SD/2; Wuang et al. 2012), average variance extracted (accepted values ≥ 0.50), composite reliability (accepted values ≥ 0.70), and standard error of measurement (accepted value < SD/2; Wuang et al. 2012).

Confirmatory factor analysis (CFA) was performed to assess the factor structure of the CAS Bangla version. Using CFA, the unidimensional factor structure suggested by the author was tested. Model fits were assessed through the χ2/df value, comparative fit index (CFI), goodness-of-fit index (GFI), Tucker–Lewis index (TLI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR). The χ2/df ratio value ≤ 2 suggests a good fit (Schermelleh-Engel and Moosbrugger 2003). However, Marsh and Hocevar (1988) suggested that this value should be less than 5. The CFI, GFI, and TLI values ≥ 0.95 suggest the good fit model (Hu and Bentler 1999). Additionally, a RMSEA value between 0.06 and 0.08 and a SRMR value ≤ 0.08 (Schreiber et al. 2006) suggest a better-fitted model.

Next, a series of multigroup CFA was performed to assess the measurement invariance of the CAS Bangla across demographic groups. In the present study, measurement invariance was assessed across age groups (18 to 29 years vs. 30 years and above) and gender (male vs. female). There were three models in multigroup CFA for each demographic—model 1 (configural invariance model: same structure across the groups), model 2 (metric model: factor loadings constrained equal across the groups), and model 3 (scalar model: factor loading and intercepts constrained similarly across the groups). A non-significant Δχ2 value suggests measurement invariance across the groups. As the Δχ2 is an excessive stringent test of invariance (MacCallum et al. 1992) and sensitive to sample size (Dimitrov 2010), in this study we used ΔCFI, ΔRMSEA, and ΔSRMR to make decisions concerning invariance. Chen (2007) recommended ΔCFI ≥ 0.010, ΔRMSEA ≤ 0.015, and ΔSRMR ≤ 0.01 as evidence of measurement invariance.

Besides the above described statistical tests, the Pearson product-moment correlation coefficient was also performed to assess the convergent validity of the CAS Bangla version.

Results

Table 1 shows the mean and standard deviation for each item, ranging between 0.28 (0.71) and 0.86 (1.12). Table 1 also shows that all items have good corrected item-total correlations ranging from 0.68 (item 5) to 0.73 (item 4). The CAS Bangla version also has good internal consistency reliabilities (Cronbach’s alpha, 0.872; McDonald’s omega, 0.879; and split half reliability through the Spearman-Brown formula, 0.864; Table 2). The single-factor model in the CFA yielded a good model fit (GFI = 0.987, CFI = 0.989, TLI = 0.977, RMSEA = 0.074, and SRMR = 0.019) except χ2/df ratio (5.001). Modification indices were examined, and the model was modified through adding a covariance between error variances for item 1 and item 4. All indices of the modified model yielded good model fit (χ2/df = 2.331, GFI = 0.995, CFI = 0.997, TLI = 0.992, RMSEA = 0.043, and SRMR = 0.013). Factor loadings ranged from 0.72 (item 5) to 0.83 (item 4). The CAS Bangla version also demonstrated acceptable test-retest reliability (r = 0.764, p < 0.001; 95% CI 0.522, 0.893), average variance extracted (0.601), composite reliability (0.882), and standard error of measurement (1.479 < SD/2 [2.067]).

Results (Table 3) of the multigroup analysis demonstrated that there was a metric and scalar invariance between the two age groups. The configural model had good model fit (χ2/df = 4.105, CFI = 0.986, RMSEA = 0.065, and SRMR = 0.0214). There were negligible changes in CFI, RMSEA, and SRMR between configural and metric models (0.002, − 0.010, 0.0042, respectively) and between metric and scalar models (0.003, − 0.004, − 0.0001, respectively). Results (Table 3) regarding invariance across gender suggest full metric invariance and partial scalar invariance between males and females. Moreover, the configural model of gender had good model fit (χ2/df = 1.809, CFI = 0.996, RMSEA = 0.033, and SRMR = 0.0164). Although there were negligible changes in CFI, RMSEA, and SRMR values between configural and metric models (0.003, 002, 0.0064, respectively), notable changes were in the CFI and RMSEA values between metric and scalar models (0.013 and 0.017). Item 4 was freed in the scalar model and showed little changes in CFI and RMSEA values from metric to scalar models (0.006 and 0.008). Although there was a difference in mean and intercept in item 4 between males and females, the CAS Bangla is a valid measure for both groups.

Total scores of the CAS Bangla version correlated strongly and positively to COVID-19 worry, anxiety, depression, and negatively to mental well-being (Table 4); this suggests the concurrent validity of the CAS Bangla version. The scale’s cutoff score parameters were based on the CAS’ original findings (Lee 2020a) and not calculated for this sample. However, to determine differences between groups, comparisons were made across gender, residence, and education statuses. An independent sample t test result showed a significant mean difference (t(727) = 4.25, p < 0.001; d = − 0.32) between males (M = 2.76, SD = 3.90) and females (M = 4.07, SD = 4.36). Additionally, a one-way ANOVA suggested non-significant mean differences in residence status (F(2726) = 0.020, p = 0.980) and education level (F(3722) = 0.993, p = 0.396). Observations for below secondary education and Ph.D. degree educational levels were excluded from this analysis due to the fewer number of them.

Discussion

The COVID-19 pandemic is threatening for the physical as well as mental health of individuals (Wang et al. 2020). To understand the impact this pandemic has on individuals—scientists, psychologists, and researchers are working on developing different tools to assess both the physical and mental health of individuals. The CAS and the Fear of COVID-19 Scale (Ahorsu et al. 2020) are among the first few documented psychopathology-related tests for COVID-19 anxiety. The CAS is the first that was validated on a large sample of specifically US adults who reported severe anxiety in the early stages of the coronavirus pandemic, including a significant sample of people diagnosed with the disease (Lee 2020a). The present study was undertaken to adapt the CAS in the Bangla language to assess dysfunctional COVID-19 anxiety among Bangladeshi people. In this adaptation process of the CAS, data were collected via an online survey, and item and scale level psychometric properties were assessed.

Results show that the items of the CAS Bangla version had high item discrimination (item-total correlations). As a discrimination index, a good item-total correlation suggests that the corresponding item can discriminate between high and low scorers, in the test that the item belongs to. The higher item-total correlation of each item indicated that the items of the CAS Bangla version would be able to differentiate between low and high scorers, which are a strong psychometric feature of this instrument. Results regarding reliabilities show that the CAS Bangla version had good internal consistency reliabilities, test-retest reliability, and composite reliability (≥ 0.7). In the original study and a replication analysis, Lee (2020a, b) found high internal consistency reliability for the CAS (αs ranged between 0.92 and 0.93). Furr (2011) suggests 0.70 to 0.80 as sufficient reliability, although there are no clear cutoff values for poor and good reliabilities. However, others suggest 0.80 or higher reliability for screening purposes (Bardhoshi and Erford 2017; Erford 2013). As internal consistency reliabilities and composite reliability of the CAS Bangla version were higher than 0.80, this scale is suitable for screening COVID-19 anxiety among Bangladeshi people.

The CFA supported the single-factor model suggested by Lee (2020a, b) studies. The single factor model of the Bangla CAS showed good model fits. The results regarding multigroup CFA suggest scalar invariance between ages 18 to 29 years and 30 years and older. Regarding gender, this scale had partial scalar invariance, as item 4 was variant between males and females. Aside from this one item, the CAS Bangla version assessed the same construct for both males and females. Lee (2020a) also showed measurement invariance between similar age groups and between genders. Results regarding correlations suggested the convergent validity of the scale as it was highly correlated to the anxiety score of the DASS-21 subscale and moderately correlated to the depression score of the DASS-21 subscale and the CWS. The moderate correlations with the depression and worry scores suggest that the CAS Bangla version assesses two different constructs. Results also showed females had higher COVID-19 anxiety scores than males. This finding is consistent with other studies that assessed general anxiety among people during the COVID-19 pandemic (Ahmed et al. 2020a; Wang et al. 2020). Altogether, our findings support the CAS Bangla version as a valid tool that exhibits appropriate psychometric properties in assessing dysfunctional coronavirus anxiety among the people of Bangladesh.

Limitations

The present study has several limitations. First, data were collected through a self-reported online survey that may have been subjected to the social desirability bias. Secondly, divergent validity was not assessed, as there were several online surveys when the data collection of this study was ongoing. From the authors’ observations, people were reluctant to participate in a relatively longer survey. Therefore, the tool for assessing divergent validity was omitted from the questionnaire to keep participants’ reports valid and complete. Future studies should use external validators to address this problem. Thirdly, data were collected using a non-clinical sample. Thus, a clinical sample should be used in further studies to validate the scale for clinical use.

Recommendations

Despite the above limitations, the CAS Bangla version has excellent psychometric properties to assess dysfunctional COVID-19 anxiety among Bangladeshi people. As this scale provides a quick assessment of anxiety related to the COVID-19 pandemic, it would be helpful for health professionals to address the general public’s mental health issues caused by COVID-19, using this screening instrument. A part from the aforementioned recommendations of using external validators and validating the scale for clinical use, a further recommendation includes having the CAS Bangla version be used to treat anxiety via the delivery of an online psychotherapy—as not only has such telehealth therapy had a proven success rate (Khatri et al. 2014), but its online form may be a more practical solution during this pandemic.

Conclusion

The CAS, developed by Lee (2020a), was the first psychopathology related screening tool for COVID-19 anxiety on a US population; additionally, it is among the first few published scales to assess its construct. This study aimed to validate a Bangla version of the CAS to increase the reach of assessing those affected by this worldwide pandemic. After conducting an online study and various analyses, our results supported the CAS to be a valid instrument for assessing dysfunctional coronavirus anxiety for the Bangladeshi general population. With the CAS Bangla version’s validation, those affected psychologically by the pandemic can be effectively screened in a quick fashion by both mental and healthcare professionals in Bangladesh. Finally, further research should explore our recommendations, such as examining the CAS Bangla version on a clinical sample as well as its treatment for COVID-19 anxiety via an online psychotherapy.
