偏执是焦虑、抑郁和经验异常的潜在原因;单独的研究表明，焦虑、抑郁和经验异常是偏执的预测因子。因此，失眠可能有助于迫害性思维的形成和维持。其目的是研究第一次在一般人群中失眠症状和偏执的关联，以及参加精神科服务的受迫害妄想者的失眠程度。失眠，迫害意念，焦虑和抑郁的评估完成了300人从一般人群和30个人与迫害妄想和非情感性精神病的诊断。强迫症状与较高水平的迫害意念明显相关。与对偏执狂的理论理解一致，焦虑和抑郁的存在部分解释了这种关联。妄想组中中度或重度失眠者占50%以上。这项研究提供了第一个直接证据，证明失眠在高度偏执的个体中很常见。睡眠困难有助于迫害性思维的发展，这似乎是合理的。有趣的暗示是，对这一群体的失眠干预可能会有减少偏执的额外好处。
Insomnia is a potential cause of anxiety, depression, and anomalies of experience; separate research has shown that anxiety, depression and anomalies of experience are predictors of paranoia. Thus insomnia may contribute to the formation and maintenance of persecutory ideation. The aim was to examine for the first time the association of insomnia symptoms and paranoia in the general population and the extent of insomnia in individuals with persecutory delusions attending psychiatric services. Assessments of insomnia, persecutory ideation, anxiety, and depression were completed by 300 individuals from the general population and 30 individuals with persecutory delusions and a diagnosis of non-affective psychosis. Insomnia symptoms were clearly associated with higher levels of persecutory ideation. Consistent with the theoretical understanding of paranoia, the association was partly explained by the presence of anxiety and depression. Moderate or severe insomnia was present in more than 50% of the delusions group. The study provides the first direct evidence that insomnia is common in individuals with high levels of paranoia. It is plausible that sleep difficulties contribute to the development of persecutory ideation. The intriguing implication is that insomnia interventions for this group could have the added benefit of lessening paranoia.
