有自杀倾向的人群中负面生活事件的发生率更高。素质压力和点燃效应模型提出了消极生活事件增加自杀风险的不同机制。不同形式的负面生活事件——冒险行为和压力源——可能对非致命性自杀未遂和自杀产生不同的影响。我们以自杀或其他原因死亡的成年人为样本，评估了冒险行为和压力源对自杀的影响、非致命性自杀未遂史以及积极的自杀准备（N = 377）。使用家庭成员访谈和附带记录审查的心理尸检程序用于完成 DSM-IV 人格障碍结构化访谈、改良生活经历量表和自杀意图量表的计划分量表中的冒险行为综合测量。即使考虑到人口统计和诊断特征，压力源也与自杀死亡显着相关。即使考虑到人口统计和诊断特征，冒险行为与非致命自杀企图显着相关。没有积极准备自杀的自杀者的冒险得分显着高于积极计划自杀的自杀者。我们的研究结果表明，冒险行为和压力源通过不同的机制影响自杀风险。冒险行为可能代表着长期存在的脆弱性，容易因自杀念头而冲动行事。压力源可能会影响情绪障碍人群发生致命自杀行为的风险。
Negative life events are elevated in suicidal populations. Diathesis-stress and kindling effects models suggest different mechanisms by which negative life events increase suicide risk. Different forms of negative life events – risk-taking behaviors and stressors – may have different effects on non-fatal suicide attempts and suicide. We assessed the effects of risk-taking behaviors and stressors on suicide, history of non-fatal suicide attempts, and active preparation for suicide in a sample of adults who died by suicide or other causes (N = 377). Psychological autopsy procedures using family member interviews and collateral record review were used to complete a risk-taking behaviors composite measure from the Structured Interview for DSM-IV Personality Disorders, the Modified Life Experiences Scale, and the planning subscale of the Suicide Intent Scale. Stressors were significantly associated with death by suicide, even when accounting for demographic and diagnostic characteristics. Risk-taking behaviors were significantly associated with non-fatal suicide attempts, even when accounting for demographic and diagnostic characteristics. Suicide decedents who did not actively prepare for suicide showed significantly higher risk-taking scores than suicide decedents who actively planned for suicide. Our results suggest that risk-taking behaviors and stressors impact suicide risk through separate mechanisms. Risk-taking behaviors may represent a longstanding vulnerability to act impulsively on suicidal thoughts. Stressors may impact risk for fatal suicidal behaviors in mood disordered populations.
