Self-reported peer victimization and suicidal ideation in adolescent psychiatric inpatients: the mediating role of negative self-esteem.

The current study investigated relationships among self-reported peer victimization, suicidality, and depression in adolescent psychiatric inpatients. Sixty-seven adolescent psychiatric inpatients at a Midwestern children's hospital completed measures of bullying and peer victimization, suicidal ideation, and depression during their inpatient stay. Analyses indicated significant moderate correlations among victimization, suicidal ideation, and depression in adolescents. Results from mediational analyses found that negative self-esteem mediated the relationship between peer victimization and suicidal ideation. To date, this study is the first to directly examine the mechanisms underlying the relationship between peer victimization and suicidal ideation in adolescent psychiatric inpatients.

Non-Suicidal self-injury and suicide in depressed Adolescents: Impact of peer victimization and bullying.

While prior research has demonstrated that peer victimization and bully perpetration contribute to non-suicidal self-injury (NSSI) and suicidal thoughts and behaviors (STBs), it remains unclear whether these interpersonal processes differentiate self-injuring adolescent suicide ideators and attempters. The study included adolescents aged 13-18 years (n = 223; M = 15.31, SD = 1.34) recruited from an acute inpatient program. Participants were divided into two groups: (1) NSSISI (n = 106): endorsed past year NSSI, current suicide ideation, and no lifetime suicide attempts and (2) NSSISI+SA (n = 117): endorsed past year NSSI, current suicide ideation, and lifetime suicide attempts. Adolescents completed clinical interviews (i.e., mental disorders, NSSI, and STBs) and self-report measures assessing peer victimization, bully perpetration, and depression severity. NSSISI+SA youth reported higher levels of peer victimization and bully perpetration than NSSISI youth (ps < 0.01, ds = 0.36-0.37). Among the NSSISI+SA youth, bully perpetration was associated with a greater number of past month suicide attempts (p = 0.02, RR = 1.07). Only peer victimization was associated with greater NSSI behaviors in the past month (p = 0.04, RR = 1.01). The study is cross-sectional, and reports of peer victimization and bully perpetration rely on self-report assessment. Peer victimization and bully perpetration differentiated adolescent suicide ideators and attempters, highlighting the need to address bully perpetration in addition to peer victimization in suicide interventions and research.

Peer victimization and suicidal ideation: The role of gender and depression in a school-based sample.

The current study investigated the relations among traditional and cyber victimization, depressive symptoms, suicidal ideation, and gender in a school-based sample of 403 9th grade (13 to 16-year-old) adolescents. Path analyses indicated that both traditional victimization and cyber victimization were associated with suicidal ideation indirectly through depressive symptoms. Although there was little evidence of gender differences in the associations among peer victimization and depressive symptoms and suicidal ideation, the relation between depressive symptoms and suicidal ideation was found to be significantly stronger for girls than boys. The current investigation confirms the complexity of the association between peer victimization and suicidal ideation and that depressive symptoms, as well as gender, may play a role in this complex relation. Future research should continue to explore the associations among victimization, depressive symptoms, and suicidal ideation within a social ecological framework.
