The aim of this study was to examine relationships between bullying and suicidal ideation. A total of 2,464 adolescents in Norway were assessed at two time points, 1 year apart [i.e., at ages 14 (T1) and 15 (T2)], with identical questionnaires. Suicidal ideation was measured by four items including both active and passive suicidal thoughts. ANOVA and standard linear regression methods were applied. Both bullied adolescents and adolescents who were aggressive toward others had significantly higher levels of suicidal ideation (p < 0.001) at age 14 (T1) than noninvolved adolescents. In the group being bullied, girls had higher levels of suicidal ideation than boys did. This was not the case for the group of adolescents who were the aggressors. In cross-sectional multivariate analyses, both being bullied and being aggressive toward others were significant (p < 0.001) predictors of suicidal ideation at age 14 (T1), when gender, age and socioeconomic status, and depressing symptom levels were controlled for. In the controlled longitudinal multivariate analyses, being bullied (p < 0.001) at age 14 (T1) predicted suicidal ideation at age 15 (T2), while aggressiveness toward others did not. Bullied adolescents (both genders) were at risk for suicidal ideation, and having an additional risk if they were depressed.
本研究旨在探讨欺凌与自杀意念之间的关系。共有 2464 名挪威青少年在两年间（即 14 岁（T1）和 15 岁（T2））接受了两次相同问卷的评估。自杀意念通过四项包括主动和被动自杀想法的项目来衡量。采用方差分析和标准线性回归方法。与未卷入的青少年相比，遭受欺凌的青少年和对他人具有攻击性的青少年在 14 岁（T1）时自杀意念水平显著更高（p<0.001）。在被欺凌的群体中，女孩的自杀意念水平高于男孩。对于具有攻击性的青少年群体则并非如此。在横断面多元分析中，被欺凌和对他人具有攻击性都是自杀意念在 14 岁（T1）时的显著（p<0.001）预测因素，同时控制了性别、年龄、社会经济地位和抑郁症状水平。在控制的纵向多元分析中，在 14 岁（T1）时被欺凌（p<0.001）预测了在 15 岁（T2）时的自杀意念，而对他人的攻击性则没有。被欺凌的青少年（无论性别）都存在自杀意念的风险，如果同时伴有抑郁则风险更高。
