当代偏执狂的理论模型表明，负面情绪、知觉异常和最近的生活事件是经历迫害意念的重要预测因素。在当前的经验抽样研究中，第一次前瞻性地考察了这些因素，作为日常生活中实时发生迫害意念、迫害信仰定罪和相关痛苦的预测因素。145名患有精神分裂症或分裂情感障碍的社区参与者每天多次完成由个人数字助理生成的自我报告评估，为期一周。他们的反应是滞后的，以便在几天内发生变量之间的动态预期关系时进行检查。大约一半的参与者报告有一些受迫害的想法，在一周内共有378名参与者报告发生了受迫害的想法。焦虑和悲伤的消极情绪状态是随后迫害意念发生的重要预测因素，但幻觉和最近的生活事件不是。在一组有多重迫害想法的人中，焦虑是信仰信念和相关痛苦的重要预测因素，而悲伤只能预测痛苦。这一发现与最近的认知理论相一致，该理论提出消极情绪状态在迫害意念的形成和维持中起因果作用，并暗示迫害意念可以通过针对焦虑和抑郁的干预来间接解决。
Contemporary theoretical models of paranoia suggest that negative emotions, perceptual anomalies, and recent life events are important predictors of experiencing persecutory ideation. In the current experience sampling study, these factors are examined prospectively for the first time as predictors of the occurrence of persecutory ideation, as well as persecutory belief conviction, and associated distress in real time in the context of daily life. One hundred and forty five community-dwelling participants with schizophrenia or schizoaffective disorder completed self-report assessments generated by a personal digital assistant multiple times a day for 1 week. Their responses were time lagged to allow examination of dynamic prospective relationships between variables as they occur within days. Approximately half of the participants reported having some persecutory thoughts, with a total of 378 reported occurrences of persecutory thoughts across participants during the week. Negative emotional states of anxiety and sadness were significant predictors of the occurrence of subsequent persecutory ideation, but hallucinations and recent life events were not. In a subsample of people who had multiple persecutory thoughts, anxiety was a significant predictor of belief conviction and associated distress, while sadness was only predictive of distress. The findings are consistent with recent cognitive theory that proposes a causal role for negative emotional states in the formation and maintenance of persecutory ideation and suggest that persecutory ideation may be addressed indirectly by interventions targeting anxiety and depression.
