Objective.文献中有一个建议，即更多的可变情感通过反复激活潜在的自杀认知来增加自杀意念。假设情感的变异性将是一个更好的预测自杀意念和相关行为比影响水平进行了测试，在个人发展为精神病的超高风险。本研究还检验了情感变异性是自杀特异性机制的预测，并且不能预测减弱的精神病现象的水平。27个超高风险个体被要求在电子手表的提示下完成六天的情感动态评级（经验抽样法）。在报告会上，参与者进行了半结构化的访谈（风险心理状态的综合评估），评估自杀和精神病相关现象的严重程度和频率。消极和积极情绪的变异性是自杀想法和行为频率的预测因素。更多变的消极情绪，而不是积极情绪，也与更严重的自杀意念和相关行为有关。情感变异性与精神病性症状的严重程度无显著相关。情感变异性似乎是一个特定的危险因素，自杀意念在个人发展为精神病的超高风险。早期干预应侧重于为个人提供调节自身情绪的技能。
Objective. There is a suggestion in the literature that more variable affect increases suicidal ideation through the repeated re-activation of latent suicidal cognitions. The hypothesis that affective variability would be a better predictor of suicidal ideation and related behaviour than affect level was tested in individuals at ultra-high risk of developing psychosis. This study also examined the prediction that affective variability is a suicide-specific mechanism and would not predict levels of attenuated psychotic phenomena.Method. Twenty-seven ultra-high risk individuals were required to complete ambulant ratings of their affect when prompted by an electronic wristwatch for six days (the experience sampling method). In the debriefing session, participants were assessed with a semi-structured interview (the Comprehensive Assessment of At-Risk Mental State), which assessed the severity and frequency of suicidality and psychosis-related phenomena.Results. The variability of negative and positive affect was predictive of the frequency of suicidal thoughts and behaviour. More variable negative, but not positive affect, was also associated with more severe suicidal ideation and related behaviour. Affect variability was not significantly related to the severity of attenuated psychotic phenomena.Conclusion. Affective variability appears to be a specific risk factor for suicidal ideation in individuals at ultra-high risk of developing psychosis. Early intervention should focus on providing individuals with skills for regulating their own affect.
