Research on risk factor for suicidal behaviors has been broadly conducted to enhance knowledge of suicide prevention. However, there are still challenges for risk factor research. Four major research gaps have been identified: (1) uncertain effectiveness of the population approach versus the high-risk approach for suicide prevention; (2) lack of a valid and convenient Chinese-version screening tool for the severity of suicidal ideation among adolescents; (3) demand for testing the prospective associations of risk factors with suicidal ideation using a longitudinal designed population-based sample; and (4) necessity of pathway analysis to explore and confirm how risk factors interact with each other and lead to suicidality. This thesis aims to address these gaps through a combination of five studies. Study 1 introduces an illness and death model to suicide prevention research. Elasticity and sensitivity analyses were performed. The findings revealed that the control of suicide incidence among the healthy population is the most effective prevention strategy whereas treatment of mental illness appears to be the least effective approach to suicide prevention. Study 2 validates the psychometric properties of the Chinese versions of Reynolds’s Suicidal Ideation Questionnaire (SIQ) and Suicidal Ideation Questionnaire Junior (SIQ-JR, a short version of the SIQ) in a sample of Hong Kong adolescents. A short, four-item version of the SIQ-JR has been suggested as an alternative to the SIQ and the SIQ-JR. Study 3 identifies the history of psychiatric treatment, depression, anxiety, hopelessness, unstable marital status, poor economic circumstance, and a recent death of a first-degree relative as significant risk factors for the incidence of suicidal ideation. The associations of change in risk factors with the development of suicidal ideation have been tested. There are gender and age differences in the patterns of such associations. Study 4 focuses on psychological factors associated with the first-ever incidence of suicidal ideation. Psychological factors have been detected generally to differ in their associations with the incidence and persistence of suicidality. The idea that depression partially mediates the effect of average life distress on the persistence of suicidal ideation has clinical value. Study 5 introduces and tests a stressor and illness model as a theoretical framework reference for future risk factor research. Risk factors are classified into stressor, illness, and pattern factors. Both the simple and complex models are tested. Evidence supported the proposed mediating role of mental disorders between negative life events and severity of suicidal ideation. A gender-specific pattern of associations between stressors, illness, and severity of suicidal ideation has also been detected. This thesis has made substantial theoretical, psychometric, and empirical contributions to the existing knowledge of suicide research. / published_or_final_version / Social Work and Social Administration / Doctoral / Doctor of Philosophy

Tolstoy, in ‘Death and the meaning of life’, says: “The truth was that life was meaningless. It was as though I had just been living and walking along, and had come to an abyss, where I saw clearly that there was nothing ahead but perdition. And it was impossible to stop and go back, impossible to shut my eyes, in order that I might not see that there was nothing ahead but suffering and imminent death, complete annihilation (Dickenson, 2001). Suicide act does not only leave family members, relatives and acquaintances shocked, but leaves feelings of anger and resentment, combined with exaggerated guilt. Suicide continues to be a pressing public health problem in South Africa. Suicide is a complete and permanent withdrawal from interaction and therefore a valid field of sociological study. The aim of the study is to explore the primary causal factors of suicide in Tembisa. A qualitative methodology is used to understand the life events, experiences and beliefs of people who attempted suicide. The focus of the research is on people who received counselling at Tembisa clinics for attempted suicide. A non-probability, purposive sample is utilized to seek information. Five respondents are interviewed. An interview schedule was formulated by the researcher. An interview schedule formulated from literature is utilized to create consistency in face-to-face interviews. The in-depth interviews facilitate exploration. Data is gathered by means of a literature review, field notes and audiotape transcribed by the researcher. Analysis of the data is done manually according to a schedule. The schedule is developed according to coding categories that are identified when working with raw data. Raw data is given to an independent coder for verification. The information gathered from the raw data is analysed and used to identify themes, which are offered as results. An extensive literature control is conducted, to compare and contrast the findings; and for the purpose of validity. From the study, methodological and theoretical conclusions are made. Methodological conclusions indicate the effectiveness of using a qualitative methodology and face-to-face interviews in exploring the question under study. The theoretical conclusions indicate the respondents’ understanding of suicide. Recommendations in terms of future research are drawn from research process and the context of the study ensures the link between results and conclusions, and aims and objectives. The research indicates multifaceted and multi-factorial aspects related to suicide. The understanding of suicide shows a continued struggle for hope. / Dr. Emmarentie Oliphant

In the present study, we examined loneliness and negative life events as predictors of suicide risk (viz., hopelessness and suicidal behaviors) in a sample of 160 Hispanic adults. Consistent with expectations, we found loneliness and negative life events to be positively associated with both hopelessness and suicidal behaviors. In addition, results of conducting hierarchical regression analyses indicated that loneliness accounted for significant amounts of variance in both measures of suicide risk, ranging from 24% to 29% of the variance. The inclusion of negative life events as a predictor was found to account for additional unique variance in hopelessness (3%), but not in suicidal behaviors, beyond what was predicted by loneliness. Finally, consistent with a diathesis-stress model, the Loneliness × Negative Life Events interaction was found to account for an additional 3% of the variance in both suicide risk measures. Implications of the present findings for future research on suicide risk in Hispanics are discussed.
