在调整未测量和测量的混杂因素后，调查青少年欺凌受害与自我伤害和自杀企图之间的独立关联程度。使用瑞典儿童和青少年双胞胎研究，我们检查了1994年至1999年出生的双胞胎（n= 13，852）。双胞胎在15岁时自我报告欺凌受害，18岁时自我伤害和自杀企图。我们创建了一个13个欺凌项目的因子得分，在三个模型中对自我伤害和自杀企图项目进行回归：1）在无关个体中，2）在双胞胎中，将暴露于更多欺凌的双胞胎与暴露于较少欺凌的双胞胎进行比较，3）在双胞胎中调整儿童精神病理学指标。在无关个体中，欺凌受害的一个标准差增加与自我伤害（比值比[OR] 1.29 [95%置信区间，1.23-1.36]）和自杀企图（OR，1.68 [1.53-1.85]）的几率增加相关。在双胞胎中，自残（OR，1.19 [1.09-1.30]）和自杀企图（OR，1.39 [1.17-1.66]）的几率降低。最后，当考虑到儿童期精神病理学时，自残和自杀企图的几率分别相对增加了14%（1.04-1.25）和25%（1.03-1.52）。结果表明，欺凌受害与自我伤害和自杀企图有着独特的联系，超过了由于不可测量和可测量因素（即，家庭脆弱性和预先存在的精神病）。然而，幅度很小，这表明除了欺凌干预措施外，还需要额外的干预和筛查来解决自杀问题。
To investigate the magnitude of an independent association between bullying victimization and self-harm and suicide attempt in adolescence after adjusting for unmeasured and measured confounding factors. Using the Child and Adolescent Twin Study in Sweden, we examined twins born between 1994 and 1999 (n=13,852). Twins self-reported bullying victimization at age 15 and self-harm and suicide attempt at age 18. We created a factor score of 13 bullying items, on which self-harm and suicide attempt items were regressed in three models: 1) among unrelated individuals, 2) among co-twins, in which a twin exposed to more bullying was compared to his/her co-twin who was exposed to less, and 3) among co-twins while adjusting for indicators of childhood psychopathology. Among unrelated individuals, a one standard deviation increase in bullying victimization was associated with increased odds for self-harm (Odds Ratio [OR] 1.29 [95% Confidence Interval, 1.23–1.36]) and suicide attempt (OR, 1.68 [1.53–1.85]). Among co-twins, the odds attenuated for self-harm (OR, 1.19 [1.09–1.30]) and suicide attempt (OR, 1.39 [1.17–1.66]). Finally, when accounting for childhood psychopathology, there was a 14% (1.04–1.25) and 25% (1.03–1.52) relative increase in odds of self-harm and suicide attempt, respectively. The results suggest that bullying victimization was uniquely associated with self-harm and suicide attempt, over and above the confounding due to unmeasured and measured factors (i.e., familial vulnerability and pre-existing psychopathy). However, magnitudes were small, suggesting that additional interventions and screenings are needed to address suicidality apart from bullying interventions.
