Being bullied by a sibling has been recently identified as a potential risk factor for developing depression and self-harm. It is unknown whether this risk extends to other serious mental health problems such as psychosis. We investigated whether sibling bullying victimization or perpetration in middle childhood was prospectively associated with psychotic disorder in early adulthood.
The current study investigated 6988 participants of the Avon Longitudinal Study of Parents and Children, a UK community-based birth cohort. Sibling bullying was reported at 12 years and psychotic disorder was assessed via a semi-structured interview at 18 years.
Involvement in sibling bullying was associated with psychotic disorder in a dose-response fashion, even after controlling for a range of confounders. Those involved several times a week were 2-3 times more likely to meet criteria for a psychotic disorder [odds ratio (OR); 95% confidence interval (CI)]: victimization (OR 2.74; CI 1.28-5.87); perpetration (OR 3.16; CI 1.35-7.41). Categorical analysis indicated that particularly victims (OR 3.10; CI 1.48-6.50) and bully-victims (OR 2.66; CI 1.24-5.69) were at increased risk of psychotic disorder. Involvement in both sibling and peer bullying had a dose-effect relationship with a psychotic disorder, with those victimized in both contexts having more than four times the odds for a psychotic disorder (OR 4.57; CI 1.73-12.07).
Parents and health professionals should be aware of the adverse long-term effects of sibling bullying.
最近发现，被兄弟姐妹欺负是患抑郁症和自残的潜在风险因素。但尚不清楚这种风险是否会扩展到其他严重的心理健康问题，如精神病。我们调查了儿童中期兄弟姐妹欺凌的受害或加害与成年早期精神病之间是否存在前瞻性关联。
本研究调查了英国社区为基础的出生队列——阿冯纵向研究父母和孩子中的 6988 名参与者。在 12 岁时报告了兄弟姐妹欺凌行为，在 18 岁时通过半结构化访谈评估了精神病。
即使在控制了一系列混杂因素后，参与兄弟姐妹欺凌也与精神病呈剂量反应关系。每周几次参与其中的人患精神病的可能性是前者的 2-3 倍[比值比（OR）；95%置信区间（CI）]：受害者（OR 2.74；CI 1.28-5.87）；加害者（OR 3.16；CI 1.35-7.41）。分类分析表明，特别是受害者（OR 3.10；CI 1.48-6.50）和欺凌-受害者（OR 2.66；CI 1.24-5.69）患精神病的风险增加。兄弟姐妹和同伴欺凌的参与与精神病呈剂量效应关系，在这两种情况下都受害的人患精神病的几率是前者的四倍多（OR 4.57；CI 1.73-12.07）。
父母和健康专业人员应该意识到兄弟姐妹欺凌的长期不良后果。
