背景：人们对情感对精神病的影响重新产生了兴趣。关于迫害妄想的心理学研究将一个突出的角色归因于与消极情感相关的认知过程：焦虑导致偏执狂对威胁的预期;关于自我的抑郁消极想法创造了一种脆弱感，其中偏执思想蓬勃发展;自我意识增强了自我作为目标的感觉。本研究的目的是检查这种情感过程与妄想患者的状态偏执。研究方法：130例妄想患者的背景下，非情感性精神病诊断（主要是精神分裂症）进行了评估，同期水平的迫害意念的5个视觉模拟量表。测量了焦虑、抑郁、威胁预期、歧义解释、自我关注和对自我的负面看法。结果：85%的患者在测试中报告偏执思维。焦虑和抑郁的症状非常普遍。当前的偏执思维与焦虑、抑郁、对威胁事件的更大预期、对模棱两可事件的负面解释、自我关注的认知风格和对自我的负面想法有关。结论：这项研究清楚地表明，一系列与情绪相关的认知偏见，每一种都可能维持妄想，与精神病患者当前的偏执思维有关。我们发现了认知内容和信息处理中的偏见。情感和精神病之间的联系是理解精神分裂症的核心。我们的结论是，情绪功能障碍的治疗应导致减少目前的精神病的经验。
Background: There has been renewed interest in the influence of affect on psychosis. Psychological research on persecutory delusions ascribes a prominent role to cognitive processes related to negative affect: anxiety leads to the anticipation of threat within paranoia; depressive negative ideas about the self create a sense of vulnerability in which paranoid thoughts flourish; and self-consciousness enhances feelings of the self as a target. The objective of this study was to examine such affective processes in relation to state paranoia in patients with delusions. Methods: 130 patients with delusions in the context of a nonaffective psychosis diagnosis (predominately schizophrenia) were assessed for contemporaneous levels of persecutory ideation on 5 visual analog scales. Measures were taken of anxiety, depression, threat anticipation, interpretation of ambiguity, self-focus, and negative ideas about the self. Results: Of the patients, 85% report paranoid thinking at testing. Symptoms of anxiety and depression were highly prevalent. Current paranoid thinking was associated with anxiety, depression, greater anticipation of threat events, negative interpretations of ambiguous events, a self-focused cognitive style, and negative ideas about the self. Conclusions: The study provides a clear demonstration that a range of emotion-related cognitive biases, each of which could plausibly maintain delusions, are associated with current paranoid thinking in patients with psychosis. We identified biases both in the contents of cognition and in the processing of information. Links between affect and psychosis are central to the understanding of schizophrenia. We conclude that treatment of emotional dysfunction should lead to reductions in current psychotic experiences.
