          Abstract

          The relationship of bullying with suicidal ideation among adolescents is controversial. Although depression has been related to bullying and suicidal ideation, little is known about the combined impacts of depression and bullying on suicidal ideation.

          A sample of 20,509 high school students from Fujian Province were selected randomly by multistage stratified sampling. All participants completed an adolescent health status questionnaire. Three categories of bullying were assessed: perpetration, victimization, and both (victimization and perpetration). The associations of these 3 categories of bullying with depression and their interaction with suicidal ideation were examined in logistic models.

          After adjustment for potential confounders, all 3 categories of bullying (perpetration, victimization, and both) were related to increased risk of suicidal ideation with odds ratios (ORs) of 1.66 (95% confidence interval [CI] 1.20–2.30), 2.74 (95% CI 2.29–3.29), and 2.83 (95% CI 2.27–3.52), respectively. There was an interaction between depression and bullying ( P = 0.001). Subgroup analyses showed a stronger association between perpetration and suicidal ideation in students with depression (odds ratio [OR] 2.97; 95% CI 1.44–6.09) than in those without depression (OR 1.65; 95% CI 1.19–2.28). The association between victimization and suicidal ideation was weaker in students with depression (OR 1.49; 95% CI 1.07–2.07) than in those without (OR 2.69; 95% CI 2.24–3.23). The association of both victimization and perpetration with suicidal ideation was weaker in students with depression (OR 2.22, 95% CI 1.43–3.47) than those without (OR 2.78; 95% CI 2.23–3.47).

          We observed an independent association of bullying with increased risk of suicidal ideation among adolescent students, and this association was affected by depression. Prospective studies should be conducted to confirm these findings.

          Youth suicide risk and preventive interventions: a review of the past 10 years.

          To review critically the past 10 years of research on youth suicide. Research literature on youth suicide was reviewed following a systematic search of PsycINFO and Medline. The search for school-based suicide prevention programs was expanded using two education databases: ERIC and Education Full Text. Finally, manual reviews of articles' reference lists identified additional studies. The review focuses on epidemiology, risk factors, prevention strategies, and treatment protocols. There has been a dramatic decrease in the youth suicide rate during the past decade. Although a number of factors have been posited for the decline, one of the more plausible ones appears to be the increase in antidepressants being prescribed for adolescents during this period. Youth psychiatric disorder, a family history of suicide and psychopathology, stressful life events, and access to firearms are key risk factors for youth suicide. Exciting new findings have emerged on the biology of suicide in adults, but, while encouraging, these are yet to be replicated in youths. Promising prevention strategies, including school-based skills training for students, screening for at-risk youths, education of primary care physicians, media education, and lethal-means restriction, need continuing evaluation studies. Dialectical behavior therapy, cognitive-behavioral therapy, and treatment with antidepressants have been identified as promising treatments but have not yet been tested in a randomized clinical trial of youth suicide. While tremendous strides have been made in our understanding of who is at risk for suicide, it is incumbent upon future research efforts to focus on the development and evaluation of empirically based suicide prevention and treatment protocols.

            Bullying, depression, and suicidality in adolescents.

            To assess the association between bullying behavior and depression, suicidal ideation, and suicide attempts among adolescents. A self-report survey was completed by 9th- through 12th-grade students (n = 2342) in six New York State high schools from 2002 through 2004. Regression analyses were conducted to examine the association between being victimized and bullying others with depression, ideation, and attempts. Approximately 9% of the sample reported being victimized frequently, and 13% reported bullying others frequently. Frequent exposure to victimization or bullying others was related to high risks of depression, ideation, and suicide attempts compared with adolescents not involved in bullying behavior. Infrequent involvement in bullying behavior also was related to increased risk of depression and suicidality, particularly among girls. The findings indicate that both victims and bullies are at high risk and that the most troubled adolescents are those who are both victims and bullies. Psychopathology was associated with bullying behavior both in and away from school. Victimization and bullying are potential risk factors for adolescent depression and suicidality. In evaluations of students involved in bullying behavior, it is important to assess depression and suicidality.

              Risk factors and life processes associated with the onset of suicidal behaviour during adolescence and early adulthood.

              This study examined associations between childhood circumstances, adolescent mental health and life events, and the development of suicidal behaviour in young people aged between 15 and 21 years. Data were gathered over the course of a 21-year longitudinal study of a birth cohort of 1265 children born in New Zealand. The measures collected included: (1) patterns of suicidal behaviour (ideation, attempt) (15-21 years); (2) social background, family functioning, parental and individual adjustment during childhood (0-16 years); and (3) time dynamics of mental health and stressful life events during adolescence and early adulthood (15-21 years). By the age of 21 years, 28.8% of the sample reported having thought about killing themselves and 7.5% reported having made a suicide attempt. The childhood profile of those at greatest risk of suicidal behaviour was that of a young person reared in a family environment characterized by socio-economic adversity, marital disruption, poor parent-child attachment and exposure to sexual abuse, and who as a young adolescent showed high rates of neuroticism and novelty seeking. With the exception of the socio-economic and personality measures, the effects of childhood factors were largely mediated by mental health problems and exposure to stressful life events during adolescence and early adulthood. Mental health problems including depression, anxiety disorders, substance use disorder, and to some extent conduct disorder, in addition to exposure to adverse life events, were significantly associated with the onset of suicidal behaviours. Findings support a life course model of the aetiology of suicidal behaviour in which risk of developing suicidal behaviour depends on accumulative exposure to a series of social, family, personality and mental health factors.
