Social and individual risk factors for suicide ideation among Chinese children and adolescents: A multilevel analysis

The objective of this study was to investigate the prevalence and predictors of suicide ideation among primary, middle and high school students. We used multilevel modelling to investigate suicide ideation among 12,733 Chinese children and adolescents aged 9–18 years from wide range of areas across China. Approximately, 32.09% of children and adolescents reported suicide ideation, with females were more likely to report suicide ideation than males (38.09% vs. 29.95%). Our results showed that the risk factors in primary school students were different from middle and high school student groups, whereas significant risk factors for middle and high school students were similar. The city's standard of living as indicated by the Engel coefficient and the city's divorce rate were positively associated with the prevalence of suicide ideation; in contrast, the school's pupil‐to‐teacher ratio was negatively correlated with elevated suicide ideation. Significant risk factors for suicide ideation included study anxiety, self‐accusation tendency, impulsive tendency, terror tendency and physical symptoms. These results have important implications for the prevention of suicide, suggesting that both contextual (city‐level) and compositional (individual‐level) factors could be important targets for prevention and intervention for children and adolescents at risk of suicide ideation.     

Suicide ideation and depression in university students in Botswana

The study aimed at exploring suicide ideation and its relationship to depression in university students in Botswana. Data were collected from 122 undergraduate students (68.9% females, 31.1% males) with a mean age of 20.02 years. Depressive symptoms were measured with an adapted version of Beck's Depression Inventory-II. In total, 47.5% of the respondents reported suicide ideation, 28.7% reported previous suicide attempts, and the mean depression score was 19.14. Suicide ideation correlated strongly with total depression scores. The level of depression severity was linearly related to suicide ideation but 14.3% of respondents who scored at the level of minimal depression and 53.8% of those who scored at the level of mild depression had also contemplated suicide. The level of education of respondents’ mothers had an inverse relationship with suicide ideation and with depression in that those whose mothers had a tertiary level education were less likely to engage in suicide ideation and had significantly lower depression scores. The results are discussed from within the specific social ecological context of Botswana.     

Testing a model of suicide ideation in college students

This study examined several risk factors-negative life events (NLE), hopelessness, and depressive symptoms-believed to commonly precipitate suicide ideation in college students. A total of 345 undergraduates participated in the study. Students completed four self-report questionnaires. Hierarchical regression analyses were used to construct a risk model of suicide ideation. This study confirmed depressive symptoms and hopelessness as predictors of suicide ideation in college students; however, NLE impacted suicidal thoughts through hopelessness and depressive symptoms. Interestingly, depressive symptoms exerted a stronger influence on suicide ideation than hopelessness. Hopelessness served as a partial mediator in the relationship between NLE and depressive symptoms; however, depressive symptoms fully mediated the relationship between NLE and hopelessness. Clinical implications for understanding suicide risk in college students are discussed.     

The Associations of Physical and Sexual Assault with Suicide Risk in Nonclinical Military and Undergraduate Samples

The associations of various forms of sexual and physical assault with a history of suicide attempts and recent suicide ideation were studied in two distinct samples: active duty military and undergraduate students. A total of 273 active duty Air Force personnel and 309 undergraduate students anonymously completed self‐report surveys of assault victimization, emotional distress, belongingness, recent suicide ideation, and previous suicide attempts. Among military personnel, rape, robbery, or violent assault was associated with a nonsignificant trend toward increased risk for suicide attempts, whereas physical abuse or battering as an adult was significantly associated with recent suicide ideation. Among undergraduates, unwanted sexual experiences as an adult and physical or sexual abuse as a child were significantly associated with increased risk for suicide attempt, but only unwanted experiences as an adult was significantly associated with increased risk for suicide ideation. Experiencing multiple forms of assault increased risk for suicide attempts and ideation in both groups. Results suggest that different types of assault contribute differentially to suicide risk in military versus undergraduate populations, but experiencing multiple types of assault is associated with increased risk in both groups.     

Predictors of suicide ideation and depression in Hong Kong adolescents: perceptions of academic and family climates

The unique dimensions of perceptions of school and family contributing to depression and suicide ideation in Hong Kong adolescents were examined in two studies. In Study 1, among 327 Hong Kong Chinese female students ages 13-18, 47% reported some suicide ideation. Suicide ideation was significantly associated with depression, test anxiety, academic self-concept, and adolescents' perceived parental dissatisfaction with academic performance. The correlation between test anxiety and depression was especially high (r = .51). Study 2 examined how three different aspects of perceived family relationship were associated with depression and suicide ideation. Among 371 Hong Kong Chinese adolescents ages 14-20, 52.6% reported suicide ideation. Low levels of family cohesion and support and high levels of parent-adolescent conflict were positively related to depression and suicide ideation in both genders. Across both studies, depression mediated associations between academic- and family-related variables and suicide ideation. Findings underscore the importance of both academic and family climate in understanding depression and suicide ideation among Chinese adolescents.     

Cultural orientation, family cohesion, and family support in suicide ideation and depression among African American college students

This study extends previous research by examining the role of communalism, family cohesion, and family support in suicide ideation and depression in African American college students. Participants were 188 African American introductory psychology students (126 female, 61 male) from a historically black college. (1) Results showed that communalism, family cohesion, and family support were positively associated with each other. Higher levels of family cohesion and family support were associated with lower levels of suicide ideation and depression. Linear regression analyses showed a main effect for communalism and family support. Having strong communal values was positively related to suicide ideation and depression. Having strong family support was associated with fewer experiences of suicide ideation and depression. Stepwise regression analyses indicated that family support explained more variance in suicide ideation and depression than family cohesion. Implications of these results for future research and practice are discussed.

Asian American college students' suicide ideation: a mixed-methods study

The purpose of this mixed-methods study was to explore the phenomenon of suicide ideation among 293 Asian American college students. Guided by T. Joiner's (2005) interpersonal-psychological theory of suicidal behavior, the authors examined the relationships among perceived burdensomeness, thwarted belongingness, self-construals, and suicide ideation. Compared with thwarted belongingness, perceived burdensomeness was a more robust predictor of suicide ideation. However, thwarted belongingness moderated the positive association between perceived burdensomeness and suicide ideation. Furthermore, interdependent self-construal and independent self-construal both weakened the link between perceived burdensomeness and suicide ideation and between thwarted belongingness and suicide ideation. The authors also conducted a qualitative analysis of participants' open-ended responses about their perceptions of why Asian American college students might consider suicide. The authors identified a core phenomenon of unfulfilled expectations as well as 2 broad themes related to this core phenomenon: unfulfilled intrapersonal expectations and unfulfilled interpersonal expectations, comprising the subthemes of (a) family, (b) relationship, (c) cultural differences, and (d) racism. These findings are discussed in terms of implications for suicide-related clinical interventions and primary prevention efforts among Asian American college students.     

Self-Criticism,Neediness, and Distress in the Prediction of Suicide Ideation: Results from Cross-Sectional and Longitudinal Studies

The aim of the present study was to test whether the maladaptive personality traits of self-criticism and neediness predict suicide ideation when controlling for general distress. Further, potential interactive effects on suicide ideation of the two traits and distress were also evaluated. Two studies with nonclinical samples were conducted. The first investigation was cross-sectional and involved a final sample of 202 community adults while the second study was longitudinal with a final sample of 207 college students. Results of Study 1 demonstrated that self-criticism, but not neediness, associated with suicide ideation and, in doing so, also interacted with distress. Neediness also tended to interact with self-criticism in the prediction of suicide ideation. Results from Study 2 were similar and confirmed the Study 1 results. Changes in self-criticism, but not changes in neediness, predicted changes in suicide ideation after statistically controlling for changes in distress. Changes in the interaction between self-criticism and distress predicted changes in suicide ideation and changes in the interaction between self-criticism and neediness tended to predict changes in suicide ideation. Results are discussed with regard to their implications for psychological intervention.
