最近的研究表明，焦虑和悲伤增加的负面情绪状态可以预测迫害意念的发生，但尚不清楚这些发现是否适用于其他亚型的妄想。目前的研究探讨了这些消极的情绪状态，以及幻觉，有偏见的推理风格（即，急于下结论），和消极的自尊前瞻性地预测控制，参考和宏伟的错觉在真实的时间的发生和各个方面，因为它们发生在日常生活中。130名患有精神分裂症或情感障碍的社区参与者连续7天每天多次完成实验室测量和个人数字助理生成的瞬时自我报告。分析的时间滞后，允许同时检查人的水平和人的变量之间的时变关系。大约一半的参与者报告在一周内至少有一次妄想经历，大约四分之一的人报告经历了所有3种妄想亚型。幻觉是当天随后几个小时内控制妄想和参照妄想发生的重要预测因素，但焦虑和悲伤等负面情绪状态则不然。负自尊预测频率的所有3妄想亚型在一周内，和推理风格的特点是减少信息收集是一个显着的预测频率的妄想控制。信念、痛苦和破坏的精神维度与每种妄想亚型的测试变量有不同的关联。
Recent research has shown that negative emotional states of increased anxiety and sadness prospectively predict the occurrence of persecutory ideation, but it is not known whether these findings extend to other subtypes of delusions. The current study explored whether these negative emotional states, as well as hallucinations, biased reasoning style (ie, jumping to conclusions), and negative self-esteem prospectively predict the occurrence and various dimensions of delusions of control, reference, and grandiosity in real time, as they occur in daily life. One hundred and thirty community-dwelling participants with schizophrenia or schizoaffective disorder completed laboratory measures and momentary self-reports generated by a personal digital assistant multiple times per day, over 7 consecutive days. Analyses were time lagged allowing simultaneous examination of person-level and within-person time-varying relationships among the variables. Approximately, half of the participants reported having at least one delusional experience during the week, and approximately, a quarter of those individuals reported experiencing all 3 delusion subtypes. Hallucinations were a significant predictor of the occurrence of delusions of control and reference over the subsequent hours of the same day, but negative emotional states of anxiety and sadness were not. Negative self-esteem predicted the frequency of all 3 delusion subtypes during the week, and a reasoning style characterized by reduced information gathering was a significant predictor of the frequency of delusions of control. Delusional dimensions of conviction, distress, and disruption had different associations with the variables tested for each delusion subtype.
