背景最近的横断面研究表明，精神病经历（PE）与自杀意念和行为有关。我们的目的是研究精神病经历（包括持续性PE）与同期和偶发性非自杀性自伤（NSSI）和自杀倾向之间的关系。参与者来自澳大利亚1896名青少年（12-17岁）的纵向队列。使用自我伤害行为问卷测量NSSI和自杀企图。采用儿童诊断性访谈量表中的项目评估精神病经历，采用一般健康问卷-12测量心理困扰。青少年心理困扰和赞同精神病的经验增加了同期和事件的NSSI和自杀未遂的几率。精神病经历本身并不能预测未来的风险。持续的精神病经历与NSSI和自杀倾向的风险增加相关。伴随精神病经历的心理困扰和持续的精神病经历是NSSI和自杀企图的重要预测因素。在青少年中筛查这些表型将有助于识别那些最有风险的青少年，为有针对性的自杀预防策略提供机会。
Background. Recent cross-sectional studies have shown psychotic experiences (PEs) are associated with suicidal ideation and behaviours. We aimed to examine associations between psychotic experiences (including persistent PE), and contemporaneous and incident non-suicidal self-injury (NSSI) and suicide attempts.Method. Participants were from an Australian longitudinal cohort of 1896 adolescents (12-17 years). NSSI and suicide attempts were measured using the Self-Harm Behaviour Questionnaire. Items from the Diagnostic Interview Schedule for Children were used to assess psychotic experiences, and the General Health Questionnaire-12 measured psychological distress.Results. Adolescents both psychologically distressed and endorsing psychotic experiences had increased odds of contemporaneous and incident NSSI and attempted suicide. Psychotic experiences alone did not predict future risk. Persistent psychotic experiences were associated with increased risk of NSSI and suicide attempts.Conclusions. Psychological distress with accompanying psychotic experiences and persistent psychotic experiences are important predictors of NSSI and suicide attempts. Screening these phenotypes in adolescents will assist in discerning those adolescents most at risk, providing opportunities for targeted suicide prevention strategies.
