Suicide resilience: A concept analysis

Abstract

Objective

Suicide resilience is gaining increasing attention from researchers because of its potential role in preventing suicide. However, it has not been clearly analyzed, and there are various meanings and terms regarding this issue. The purpose of this analysis, therefore, was to conceptualize the concept of suicide resilience.

Methods

Walker and Avant's method of concept analysis was used to identify the antecedents, attributes, and consequences of suicide resilience. The literature was searched using PubMed, PsychINFO, Embase, Web of Science, CINAHL, CNKI, and WanFang databases with no limitation on publication date. The search included peer-reviewed journal articles and dissertations related to suicide resilience published in English or Chinese.

Results

52 articles were identified to provide information for this concept analysis. Five defining attributes of suicide resilience were identified: social support, coping strategies, psychological capital, meaning in life, and sense of responsibility. Antecedents of suicide resilience were high suicide risk events, and consequences of suicide resilience were keeping vulnerable individuals stay away from or overcoming suicidality.

Conclusions

The result of the analysis provided a more clear definition of suicide resilience. The identified defining attributes, antecedents, and consequences can be further tested and used to develop potential interventions. Future research is needed and will help to advance our understanding of the scope.

Introduction

Suicide is a leading cause of death worldwide, presenting a significant public health issue (1). According to the World Health Organization (WHO), over 700,000 individuals die by suicide annually. It is estimated that for each suicide death, there are many more individuals who attempt suicide or have serious thoughts about taking their lives (2). Given the far-reaching harmful effects of suicide on individuals, families, and societies, it is crucial to advance suicide prevention. Currently, research on suicide prevention has mainly focused on the risk factors that increase an individual's vulnerability to suicide, and a bunch of these factors such as psychiatric disorders, suicidal ideation, and prior suicide attempts, have been identified (3, 4). These studies enabled us to gain a much deeper understanding of suicide and find vulnerable individuals timely. However, several researchers have indicated that the predictive validity of these risk factors is limited, and a sole focus on suicide risk factors is not enough for suicide prevention strategies (5). Recently, there has been a shift toward additional consideration of factors that confer resilience against suicide (6).

Resilience is an emerging concept in suicide research. The notion was derived both from ecology and psychology, and used by various disciplines (7). Although it has different meanings in different contexts, resilience generally refers to the ability, outcome, or dynamic process of overcoming adversity adaptively (8). With the observation of the fact that a number of individuals exposed to high suicide risks would not be suicidal, researchers in the suicide field have become more and more interested in the phenomenon of resilience (9). Empirical findings have indicated that resilience represents an intermediate between suicide risk factors and suicidality, and may mitigate the adverse effect of suicide risk factors (10, 11). Furthermore, individuals with low resilience were associated with an increased risk of lifelong suicidal behaviors (12). Thus, resilience is increasingly recognized as a suicide protective factor. In line with the broader research, resilience in suicide has also focused on identifying factors that can facilitate resilience, and a repertoire of potential factors from general resilience studies has been found (13). Nevertheless, it is suggested that some of these factors, such as positive attributional style and meaning in life, exhibit better protective qualities in the specific context of a suicidal crisis (14, 15). Meanwhile, a cluster of these factors shows better predictive validity of who can be resilient to suicide risks (16). Hence, to better understand and investigate resilience in suicide, researchers have termed it suicide resilience (17).

While there is a growing body of work on suicide resilience, the concept remains ambiguous. Currently, there are several inconsistent definitions of the term. For example, Osman defines suicide resilience as the perceived ability, resources, or competence to regulate suicide-related thoughts, feelings, and attitudes (17); whereas Johnson asserts that suicide resilience is a perception or set of beliefs that buffer individuals from suicidality in the face of stressors (14). Moreover, the process view of general resilience has dramatically influenced the definition of suicide resilience. Some scholars investigated suicide resilience as a dynamic process and used the term such as suicidal recovery to describe it (18). Additionally, there are several other phrases for suicide resilience, such as resilience to suicidality, psychological resilience to suicidal experience, and overcome suicidality (14, 19, 20). Due to these existing fuzzy interpretations, the recent increase in literature on suicide resilience may cause more confusion than clarity among researchers and clinicians, impeding precise translation of the concept into practice.

It is increasingly acknowledged that resilience is a promising intervention target for individuals facing adversity, including suicidal risk. Few researchers have developed and implemented resilience-oriented programs, indicating that they can reduce participants' suicide risk (21, 22). However, all of the programs targeted promoting general resilience, rather than suicide resilience. This may be because the suicide resilience concept is still unclear and our knowledge of suicide resiliency factors is limited. Although existing interventions have been proven to be beneficial, interventions specifically designed for suicide resilience are believed to be more effective for those in a suicidal crisis (14). Consequently, there is a dearth of research to clarify the concept of suicide resilience to further improve existing suicide prevention strategies.

In this study, we analyzed the concept of suicide resilience to address the above-mentioned research gap using Walker and Avant's concept analysis framework. Although there are various approaches for concept analysis, Walker and Avant's method is the most widely used one (23). Numerous researchers, particularly in nursing, have employed this method to examine the basic elements of health-related concepts, such as digital resilience, perinatal resilience, and vaccine literacy (24–26). Through its systematic steps, we expect to provide clarity for researchers and clinicians about suicide resilience and stimulate more research on the issue.

Methods

Concept analysis method

Walker and Avant's method of concept analysis was used. It involves eight iterative steps to guide a deeper understanding of a concept. The eight steps include selecting a concept, determining the aims of analysis, identifying all uses of the concept, determining the defining attributes, identifying a model case, identifying additional cases, identifying antecedents and consequences, and defining empirical referents (27). Adaptation of these steps in the study was shown in Table 1.

Adaptation of Walker and Avant steps of concept analysis.

Steps of concept analysis	Description of the steps in this study
1. Select a concept	Suicide resilience was selected as the concept for this analysis
2. Determine the aims of analysis	This analysis aimed to conceptualize suicide resilience
3. Identify all uses of the concept	Identify possible uses of the concept of suicide resilience from various resources such as dictionaries and research databases
4. Determine the defining attributes	Determine the characteristics that are most frequently associated with the concept of suicide resilience
5. Identify a model case	Identify an example of suicide resilience that contains all the defining attributes
6. Identify additional cases	Two additional cases (borderline and contrary cases) were identified in this analysis. A borderline case is an instance that contains most (but not all) defining attributes of suicide resilience. A contrary case is an instance that contains none of the attributes
7. Identify antecedents and consequences	Identify the events that take place prior to the occurrence of suicide resilience, and those occur as an outcome of the appearance of suicide resilience
8. Define empirical referents	Define the empirical referents that measure the existence and attributes of suicide resilience

Data source

A systematic search was conducted in online databases, including PubMed, PsychINFO, Embase, Web of Science, CINAHL, CNKI (Chinese), and Wanfang (Chinese) on Aug 30, 2022. We used the following terms in each database: “suicid^*,” “self-harm,” “self-injur^*,” “self-destruct^*,” “self-inflict^*,” “self-mutilat^*,” “overdos^*,” “self-poison^*,” “resilien^*,” “hardiness,” “buffer^*,” “bounce back,” “recover^*,” “resist^*,” “rebound,” “adapt^*,” “overcome^*.” The online databases were searched for titles, abstracts, or topics/subjects containing these terms. The Boolean operator “OR” was used to connect the similar concept, and “AND” was used to combine diversity. No date limitation was applied in the search strategy. The search strings in each database are presented in Supplementary material. In addition, the reference lists of relevant literature were searched manually to reduce the risk of missing potentially important research.

Data selection

The inclusion criteria for selecting relevant articles were: (i) discussing or investigating resilience specifically to suicidality; (ii) referring to at least one of the following items of suicide resilience: definition, attributes, antecedents, consequences, or measurement techniques; (iii) peer-reviewed journal articles, or dissertations in English or Chinese. The exclusion criteria were: (i) only focusing on general resilience that is unrelated to suicide; (ii) focusing on resilience beyond the level of the individual (e.g., family resilience). Of the original 70,619 studies that were found, 39,312 studies remained after excluding duplicates as potential eligible citations. Based on the title and abstract screening level, 38,796 studies were removed, which was obviously against eligibility criteria. Afterward, we thoroughly read the full text of the remaining 516 studies and included 52 articles that were particularly relevant to this analysis. Figure 1 is the PRISMA flowchart of the whole selection process.

Data analysis

To analyze data, we read each article in detail and extracted the following information from them: detailed characteristics, study sample, attributes, antecedents, consequences, and measurements of suicide resilience (Table 2). Additionally, all listed attributes were put together in another file to more clearly find the characteristics frequently relevant to the concept of suicide resilience. In this separate file, we regrouped synonymous and closely related attributes into the same theme. We then counted the number of articles that mentioned the theme and selected the top-mentioned themes for further analysis. The selection of attributes was discussed and reviewed by all authors throughout.

Results

The 52 articles included in the analysis were published between 2003 and 2022, and were from the following countries/regions: Australia (N = 4), Canada (N = 9), Germany (N = 1), New Zealand (N = 1), Norway (N = 1), Spain (N = 2), Sweden (N = 2), Taiwan (N = 5), United States (N = 18), United Kingdom (N = 9). The study design was quantitative (N = 27), qualitative (N = 21), and review (N = 4). A summary of study information is presented in Table 2.

Uses of the concept

The first and second steps in the Walker and Avant analysis method have been described in the Introduction section. And the third step in this method is to identify various usages of the concept (27). To achieve this goal, dictionaries and literature were used.

Dictionary definitions of suicide resilience

The concept of suicide resilience includes the two sub-concepts of suicide and resilience. Suicide is defined by Merriam-Webster's dictionary as “the act or an instance of taking one's own life voluntarily and intentionally” (73). The Oxford dictionary also defines the word as “the act of killing oneself deliberately” (74). Resilience, another concept, is defined by Merriam-Webster's dictionary as “an ability to recover from or adjust easily to misfortune or change” (75). According to the Oxford dictionary, resilience is “the ability of people or things to recover quickly after something unpleasant” (76). In this broad sense, suicide resilience would be described as an ability to recover from the adversity that may leads individuals to take their life deliberately.

Use of suicide resilience in literature

The emergence of the suicide resilience concept is due to the increasing attention on psychological resilience. In psychology, resilience has three inconsistent definitions. It is a personal trait that helps people do well despite adversity, a positive outcome of maintaining mental health despite significant stress or a dynamic process of adapting well to unfavorable circumstances (77, 78). These definitions were applied to the suicide field and greatly affected the concept of suicide resilience.

The term suicide resilience was first used by Osman as the perceived ability, resources, or competence to regulate suicide-related thoughts, feelings, and attitudes (17). Osman also mentioned that suicide resilience incorporated a set of suicide protective factors and divided them into three domains, including internal protective, external protective, and emotional stability. Johnson refers to suicide resilience as positive self-appraisals and suggests that it will buffer against the pernicious impact of stress (34). Later, Johnson defined suicide resilience as a perception or a set of beliefs that buffer individuals from suicidality when facing stressors and developed the buffering hypothesis where suicide resilience factors are not merely protective factors (14). Meanwhile, some researchers directly take the definition of psychological resilience to investigate suicide resilience without giving a specific definition (29, 30).

In the literature, the terms used to describe suicide resilience were also called several other similar terms. Notably, when the type of suicide phrase is a suicide attempt, recovery was found to be the most commonly used word, which can be interpreted as the process definition of suicide resilience (18, 46). Except for suicide resilience, other terms included resilience to suicide, resilience to suicidality, suicidal recovery, overcome suicidality, recovery from suicide, or psychological resilience to suicidal thoughts and behaviors (20, 49).

Defining attributes of suicide resilience

The fourth step in the method is to find defining attributes of suicide resilience, that is, the characteristics frequently associated with the concept. By doing so, the concept of suicide resilience can be distinguished from others (27). After an exhaustive screening of the included articles and consultation with the research team, the top five mentioned themes which have significantly higher sum scores than the others were selected as suicide resilience attributes. These attributes are social support, coping strategies, psychological capital, meaning in life, and sense of responsibility.

Social support

Social support is a central word in the reviewed literature, with a total of 28 articles mentioned (39, 40, 50, 54, 55, 64). Across studies, individuals who have higher levels of social support are less likely to consider suicide and can recover from being suicidal faster. Social support can come from various sources, including family, partners, friends, relatives, healthcare professionals, community, religion, and pets (43, 46, 59). The social support system for people at high risk of suicide has been identified as a significant influencer on resilient outcomes. Gulbas et al. (56) examined trajectories of wellbeing following a suicide attempt through a longitudinal qualitative research design within 17 Latina teens. They identified three distinct profiles which were labeled as “resilience trajectory” (N = 5), “tenuous growth trajectory” (N = 6), and “chronic stress trajectory” (N = 6). Participants in the “resilience trajectory” categories reported improvements in relationships with family or peers over time, while the other two categories did not report that. Meanwhile, mental health professionals were shown to play a critical role in facilitating the recovery process for participants in every resilient case. Several studies also indicated that receiving support from significant others and professional services was of paramount importance, especially during times of high suicide risk (18, 58).

Coping strategies

The second suicide resilience attribute is coping strategies, with a total of 19 articles mentioned (18, 28, 35, 43, 54). Coping strategies refer to the cognitive and behavioral activities individuals engage in to deal with stressful situations encountered in life (79). Positive and healthy coping strategies are inversely related to suicidal ideation and behaviors. Gulbas et al. (56) reported that participants who developed more coping skills were more likely to belong to the resilience groups. Harris et al. (58) reported that talking to people and performing daily activities that demanded a level of concentration (e.g., exercising, listening to music, cooking, and playing computer games) were helpful for patients with schizophrenia diagnoses to suppress their suicidal ideation. Several other research also concluded that emotional expression through talking or writing played an essential role in a suicidal recovery process (29, 71).

Psychological capital

A third suicide resilience attribute is psychological capital, which was mentioned in 18 articles (35, 36, 49, 63, 70). Psychological capital is defined as an individual's positive psychological state of development. Initially, it comprises four positive psychological resources: self-efficacy, optimism, hope, and resilience (80). Recently, there is growing discussion to include related nomological constructs such as wellbeing, gratitude, grit, emotional intelligence, mindfulness, and forgiveness into the concept (81). It is selected as an attributes to reflect the broad personal characteristics which are studied frequently in the suicide resilience field. For example, both Kumar et al. (66) and Yu et al. (70) reported that being optimistic could buffer against suicidality risk in the face of PTSD or depressive symptoms. Kleiman et al. (36) reported that participants with a high level of gratitude and grit were characterized with greatest reduction in suicidal ideation over time. Other variables, such as self-efficacy and mindfulness, have been demonstrated to have the same functioning (9, 49).

Meaning in life

Meaning in life is linked to suicide resilience with a total of 16 articles mentioned (15, 36, 42, 67, 68). It is a strong protective factor against suicide. Several studies have suggested that individuals with a higher level of meaning in life are less likely to develop suicide ideation with associated risk factors. There is no consistent definition of meaning in life, but all of them share three common features: cognitive component, motivational component, affective component (82). The first component is about making sense of one's experiences in life. Harris et al. (58) and Ridge et al. (72) reported that having an understanding of personal distress and suicidal experience could lead to reconciliation and acceptance of this experience, which was key aspects of establishing suicide resilience. The second component is about the pursuit and attainment of worthwhile goals, and the final component is about feelings of satisfaction, and happiness accompanying goal achievement. Zaheer et al. (59) and Everall et al. (29) reported that creating goals for the future had contributed to the increase of suicide resilience.

Sense of responsibility

Sense of responsibility compared to the attributes above is linked to suicide resilience with a total of 7 articles mentioned (29, 30, 54, 58). It is defined as awareness of one's obligation (40). Research demonstrates that sense of responsibility has two types, whether responsibility to others or personal responsibility. Several participants described being worried or realized about the effects their suicidal ideation or behaviors would have on their parents or peers. Chan et al. (43) reported this kind of awareness helped individuals to go on living. In addition, Sun et al. (18) reported the feeling of living for family could contribute to recovery after a suicide attempt. Other participants described that they need to take responsibility for themselves and their health. For example, Tofthagen et al. (48) reported that this awareness leads individuals to quit suicidal behaviors.

Cases

According to the Walker and Avant method, several cases are required to further clarify the concept of suicide resilience (27). Here, we present cases that: include all defining attributes (i.e., model cases), contain some but not all of the defining attributes (i.e., borderline cases), and absence of the defining attributes (i.e., contrary cases). The cases were adapted from the literature or constructed by authors.

Model case

Collin is a 22-year-old college student. He grew up in a rural family where his father did not talk about emotions. In his early adolescence, he secretly found out that his father had an affair which worsened their relationship. At the time, he also had a distant relationship with his mother and siblings, as well as school friends. Collin felt unhappy and perplexed by his negative emotions. He had suicidal thoughts often and once nearly attempted it. As time went by, he formed a close relationship with a new group of friends and began talking more openly about himself and his experiences (social support, coping strategies). He found that his friends were very supportive and gave him a reason to be excited about life (meaning in life). His relationship with his siblings dramatically improved in his late teen years. His siblings would often choose him to turn to when they needed help or support, which made him feel he had a significant role in the family (sense of responsibility). Collin gradually gained the confidence to accept himself and sees himself as being a strong person who cannot be stopped and who will figure out a way to deal with everything (psychological capital). He is also optimistic about the future, believing that it will bring him success and happiness (meaning in life).

Borderline case

Andy is a 36-year-old man who attempted suicide a few years ago. After realizing its negative impact on his family who always support him no matter what, he felt a strong responsibility to live for them. He found a new job as a salesman. He can find a little meaning in the job when helping his customers. However, he felt that he had become a lot more introverted and always had a sense of inferiority after a suicide attempt, which made him have great difficulties in interpersonal communication. Despite his family being supportive, he would not talk to them about his trouble. He found it effective to let out negative emotions through exercising, listening to music, and playing games. Nevertheless, sometimes he would be overwhelmed by the negative feelings and have suicidal thoughts during this tough time.

Contrary case

Katie is a 14-year-old middle school student with a diagnosis of depressive disorder. She encountered school bullying and had a hard time going through the experiences. She also has a poor relationship with her parents and almost has no true friends. Her only pleasure in life was her pet cat. She always thought that she had no value in this world and life had no meaning at all. When she felt depressed, she could not find an effective coping strategy to deal with the torturing feeling. She considered suicide as a relief and had attempted suicide by self-poisoning several times. Although she was rescued in every attempt, she still felt suicidal all the time.

Antecedents

Antecedents are the events or incidents that lead to the occurrence of the concept. The main antecedent of suicide resilience is the events that may place an individual at high risk of suicide. It may be adversity such as the coming-out process, stressful life events, combat distress, posttraumatic stress symptoms linked to sexual assault or childhood abuse, being in late life, depressive symptoms, and a diagnosis of schizophrenia (28, 34, 42, 44, 50, 64, 66, 67). This adversity also includes events directly relating to suicide, which are the strongest predictors of future suicide, such as suicide ideation or suicide attempt (71, 72).

Consequences

Consequences are the events or incidents that occur as a result or outcome of the concept. When individuals demonstrate suicide resilience, outcomes are divided into two types. For those who have not been suicidal yet, suicide resilience enables them to cope effectively with a feeling of despair and buffer them from adversity which heightens suicide risk against the development of suicidal thoughts and behaviors (28, 39, 50). For those who have already been suicidal, suicide resilience can help them overcome suicidality and regain the desire to be alive or transition them from a higher to lower risk of suicide (15, 32, 49). Regardless, the nature of the event is the reduction of suicide risk.

Empirical referents

The final step of this analysis is defining the empirical referents which can be used to measure the existence or attributes of the concept. In total, six specific instruments of suicide resilience were identified (16, 17, 34, 47, 61, 65). The detail of each measure's information and involved attributes are shown in Table 3. None of these measures mentioned all defining attributes. Hence, the existing dimensions of them may miss some features of individuals with suicide resilience. Overall, suicide resilience inventory, the suicidal recovery ability scale, and the scale of resilience to suicide attempts cover the most attributes, which suggests they may be more probable measures. Except for suicide resilience inventory and resilience appraisal scale, other scales were all developed in recent years and have not been tested in different cultures.

Discussion

In this concept analysis, we identified defining attributes, antecedents, consequences, and empirical references of suicide resilience by applying the Walker and Avant's method, providing a clearer and comprehensive insight into the concept of suicide resilience. Considering all results, we propose the definition of the concept as: suicide resilience is the ability and dynamic process of an individual who is under high suicide risks to avoid being suicidal, transition from a higher to lower risk of suicide, or recover from suicidality, which can be enhanced by the presence of attributes such as social support, coping strategies, psychological capital, meaning in life and sense of responsibility. A conceptual model of suicide resilience was presented in Figure 2.

Our analysis showed that social support, coping strategies, psychological capital, meaning in life, and sense of responsibility were the five attributes of the concept of suicide resilience. The use of case studies further assists in understanding the concept of individuals applying the presence or absence of the attributes in their lives. Some of our results are in line with other studies on resilience. Both social support and coping strategies are commonly mentioned as attributes whether in general or specific resilience research (25, 83, 84). Several positive personalities contained in psychological capital such as optimism and self-efficacy are also popular attributes in similar research (83, 85). However, the other two seem to be specific attributes of suicide resilience.

The existing body of research indicated that events proven to increase suicide risk are the antecedents of suicide resilience. This is in accordance with several other research which reveals that the antecedents of specific resilience are related adversity (86). Harris et al. (58) also demonstrated that individuals can find out whether they have suicide resilience or not unless they have experienced such problems. When encountering suicide-related adversity, individuals with greater suicide resilience levels are more likely to have positive consequences, such as avoiding the development of suicide ideation. Otherwise, they may be trapped in a suicidal circle. Fortunately, more and more studies have revealed that suicide resilience was not a static state, but a dynamic process (18, 58). According to these findings, high level of suicide risks can not only be a challenge but also serve as an opportunity to cultivate or improve suicide resilience.

To prevent suicide risk by enhancing the level of suicide resilience, effective empirical referents are essential. Populations who are vulnerable to suicidality can be identified by using these tools, which can help facilitate the design of early intervention programs. Nevertheless, we only find six scales to measure suicide resilience in literature, and none of them have been widely used. This is consistent with the fact that the concept of suicide resilience has not been widely acknowledged. Based on our analysis, there are no matching measurements that contain all defining attributes. In the future, the existing scales need to be further tested, especially in different cultures, and more suicide resilience scales should be developed. Our suicide resiliency attributes can provide a reference when designing such scales.

This concept analysis has great implications for practice. First, this study informs researchers and clinicians of a growing body of literature on suicide resilience and provides them with a deep understanding of the concept. By doing so, researchers and clinicians can be more aware of the crucial role suicide resilience played in the suicide field, facilitating them to conduct more research on this theme. Second, suicide resiliency attributes identified in this analysis can offer valuable points of intervention to support populations under high suicide risks. Currently, there is rarely explicit or implicit attention to attributes such as meaning in life in mainstream clinical interventions for suicide, which have been found to be useful (36). Hence, more clinical interventions targeting attributes are needed in the future. Third, suicide resilience is defined as a dynamic process which means it will change over time. However, most existing studies on suicide resilience adopt cross-sectional design. Therefore, in order to better understand the concept, more investigation using longitudinal study designs is essential.

Finally, some limitations to this study need to be acknowledged. First, in the selection process of included articles, there might be a risk of bias without quality assessment. Second, we only included articles available in English or Chinese and, therefore, the results might not generalize beyond the settings. Third, suicide resilience research is evolving, which means the results are tentative. It is essential to regularly revisit this analysis to see whether there has anything new.

Conclusion

This research tried to clarify the concept of suicide resilience and defined it by way of the Walker and Avant concept analysis method. The clarification of the concept may improve researchers' and clinicians' understanding of the nature of suicide resilience, raise their awareness of the importance of assessment, and stimulate more interventions aiming at promoting suicide resilience. Considering that research investigating suicide resilience still use different terms and concepts, which may cause confusion and hinder more research in this area, we hope that this analysis will help to guide future research and interventions by providing a more consistent understanding.
