Suicidal adolescents' experiences with bullying perpetration and victimization during high school as risk factors for later depression and suicidality.

This is the first study to examine the extent to which frequent involvement in high-school bullying (as a bullying perpetrator, victim of bullying, or bully-victim) increases the risk for later depression and suicidality beyond other well-established risk factors of suicide. The study included 96 students who reported being a bully, a victim, or a bully-victim, and also reported depression, suicidality, or substance problems during an initial suicide screen. These students were interviewed 2 years later and were compared with 142 youth identified during the initial screen as "suicide-at-risk" by virtue of their depression, suicidal ideation, attempts, and substance problems, but who did not report any involvement in bullying behavior. Students who reported both bullying others and other suicide-related behaviors at baseline had higher suicide ideation and were more functionally impaired at follow-up than students who reported suicide-related behaviors but were not involved in bullying. Preventive efforts in high school should target those children who are characterized by both psychological disturbance and bullying, especially the frequent bullies.

Bullying and suicidal behaviors among urban high school youth.

To determine whether involvement in bullying as a perpetrator, victim, or both victim and perpetrator (victim-perpetrator) was associated with a higher risk of suicidal ideation or suicide attempts among a multiethnic urban high school population in the United States. In 2008, a total of 1,838 youth in 9th-12th grades attending public high school in Boston, MA, completed an in-school, self-reported survey of health-related behaviors. Logistic regression was used to evaluate the relationship between bullying behaviors and self-reported suicidal ideation and suicide attempts within the 12 months preceding the survey. Students who reported having been involved in bullying as a perpetrator, victim, or victim-perpetrator were more likely than those who had not been involved in bullying to report having seriously considered or attempted suicide within the past year. When age, race/ethnicity, and gender were controlled, students who were victim-perpetrators of bullying were at highest risk for both suicidal ideation and suicide attempt. Urban youth who have been bullied as well as those who have bullied others are at increased risk of suicidal ideation and suicide attempts.

Suicidal ideation and school bullying experiences after controlling for depression and delinquency.

This cross-sectional study examines differences in the frequency of suicidal ideation and suicidal behaviors across a group of verbal bullies, bully-victims, victims, physically aggressive bullies, and students not involved in bullying. A large sample of middle school students (n = 661; fifth through eighth grades; ages 10-13 years of age) completed a pencil-and-paper survey that included the University of Illinois Bully, Fight, and Victim scales. Students also self-reported how often they had thought of killing themselves or deliberating hurting themselves in past 6 months, and provided information about delinquent behaviors and symptoms of depression and anxiety. We used cluster analysis to create bully-victim subtypes: uninvolved (n = 357), victims (n = 110), verbal bullies (n = 114), bully-victims (n = 29), and physically aggressive bullies (n = 42). Approximately 32%-38% of verbal bullies and victims, 60% of bully-victims, and 43% of physically aggressive bullies reported suicidal ideation, compared with 12% of uninvolved youth. Similarly, 24%-28% of verbal bullies and victims, 44% of bully-victims, and 35% of physically aggressive bullies reported deliberately trying to hurt or kill themselves, compared with 8% of uninvolved youth. Females in the bully-victim subtype reported particularly elevated suicidal ideation and behavior. After controlling for delinquency and depression, differences in suicidal thoughts and behaviors emerged only between uninvolved youth and the victim and bully-victim groups, but these differences were minimal. Findings highlight that at a bivariate level, involvement in bullying in any capacity is linked to increased risk for suicidal ideation and behavior, and echoes previous literature documenting particularly strong mental health implications for bully-victims. Furthermore, this study points to the importance of considering delinquency and depression in conjunction with suicidal ideation and behaviors.

High school bullying as a risk for later depression and suicidality.

This is the first study to examine whether high school students experiencing frequent bullying behaviors are at risk for later depression and suicidality. A total of 236 students who reported frequent bullying behavior without depression or suicidality during a suicide screening were interviewed 4 years later to reassess depression, suicidal ideation, attempts, substance problems, and functional impairment and were compared to at-risk youth identified during the screen, including 96 youth who also experienced bullying behavior. Youth who only reported frequent bullying behaviors (as bullies, victims, or both) did not develop later depression or suicidality and continued to have fewer psychiatric problems than students identified as at-risk for suicide. Students who experienced bullying behaviors and depression or suicidality were more impaired 4 years later than those who had only reported depression or suicidality. Thus, assessment of bullying behaviors in screening protocols is recommended.
