Emerging evidence suggests that sibling aggression is associated with the development of high-risk behavior. This study investigated the relationship between sibling bullying perpetration and victimization in early adolescence and high-risk behavior in early adulthood. Sibling bullying was assessed at 12 years in 6,988 individuals from the Avon Longitudinal Study of Parents and Children, a birth cohort based in the UK and high-risk behavioral outcomes were assessed at 18-20 years. Frequent sibling bullying perpetration predicted antisocial behavior (OR = 1.74; 95%CI, 1.38-2.20), while frequent sibling bullying victimization increased the odds of nicotine dependence (OR = 2.87; 95%CI, 1.55-5.29), even after accounting for peer bullying and parent maltreatment. Categorical analysis revealed that particularly bullies and bully-victims were at risk of developing high-risk behavior. Finally, this study found that adolescents who were involved in bullying perpetration across multiple contexts (home and school) had the highest odds of reporting antisocial behavior (OR = 3.05; 95%CI, 2.09-4.44), criminal involvement (OR = 2.12; 95%CI, 1.23-3.66), and illicit drug use (OR = 2.11; 95%CI, 1.44-3.08). Findings from this study suggest that sibling bullying perpetration may be a marker of or a contributory factor along the developmental trajectory to antisocial behavior problems. Intervention studies are needed in order to test whether reducing sibling bullying can alleviate long-term adverse social and behavioral outcomes.
新出现的证据表明，兄弟姐妹之间的攻击行为与高危行为的发展有关。本研究调查了青少年早期兄弟姐妹欺凌行为的实施和受害与成年早期高危行为之间的关系。在英国基于出生队列的阿冯纵向研究父母和儿童中，在 12 岁时评估了兄弟姐妹欺凌行为，在 18-20 岁时评估了高危行为结果。频繁的兄弟姐妹欺凌行为的实施增加了反社会行为的可能性（OR=1.74；95%CI，1.38-2.20），而频繁的兄弟姐妹欺凌受害增加了尼古丁依赖的可能性（OR=2.87；95%CI，1.55-5.29），即使考虑到同伴欺凌和父母虐待也是如此。分类分析表明，特别是欺凌者和欺凌受害者有发展高危行为的风险。最后，本研究发现，在多个环境（家庭和学校）中参与欺凌行为的青少年报告反社会行为（OR=3.05；95%CI，2.09-4.44）、犯罪参与（OR=2.12；95%CI，1.23-3.66）和非法药物使用（OR=2.11；95%CI，1.44-3.08）的可能性最高。本研究结果表明，兄弟姐妹欺凌行为的实施可能是反社会行为问题发展轨迹中的一个标志物或促成因素。需要进行干预研究，以测试减少兄弟姐妹欺凌是否可以减轻长期的不良社会和行为后果。
