Trower and Chadwick's (1995) theory of two types of paranoia ('poor me' and 'bad me') provides a framework for understanding the seemingly contradictory evidence on persecutory delusions. Paranoia has been argued to defend against low self-esteem, but people with persecutory delusions report high levels of emotional distress and, in some instances, low self-worth. The current study investigates attributions and emotions in a sample of people with early psychosis who have persecutory delusions. 'Poor me' paranoia has been found to be more frequent than 'bad me' paranoia in the early stages of psychosis. Anger and a tendency to blame other people are hypothesized to characterize 'poor me' paranoia.
The study had a cross-sectional design. Twenty individuals with early psychosis, 21 clinical controls with depression and 32 healthy volunteers completed a thorough assessment of emotions and attributions.
The 'poor me' paranoia group showed higher levels of anger, anxiety and depression than the non-clinical control group. Self-esteem and guilt were however preserved. A tendency to blame others but not themselves was characteristic of the 'poor me' paranoia group whereas people in the clinical control group tended to self-blame for failures. Anger, but not self-esteem, was associated with an attributional bias characterized by blaming other people instead of oneself.
In conclusion, anger, a previously overlooked emotion in the study of persecutory delusions, warrants further attention. The other-directed nature of this emotion highlights the potential role of interpersonal schemas in understanding paranoia.
特罗尔和查德威克(1995年)提出的两种偏执类型(“可怜的我”和“糟糕的我”)理论为理解关于被害妄想的看似矛盾的证据提供了一个框架。有人认为偏执是为了抵御低自尊,但有被害妄想的人报告称情绪困扰程度很高,在某些情况下自我价值感较低。本研究调查了有被害妄想的早期精神病患者样本中的归因和情绪。研究发现,在精神病早期,“可怜的我”型偏执比“糟糕的我”型偏执更常见。愤怒和指责他人的倾向被假设为“可怜的我”型偏执的特征。
本研究采用横断面设计。20名早期精神病患者、21名临床抑郁症对照者和32名健康志愿者完成了对情绪和归因的全面评估。
“可怜的我”型偏执组比非临床对照组表现出更高水平的愤怒、焦虑和抑郁。然而,自尊和内疚感得以保留。“可怜的我”型偏执组的特征是倾向于指责他人而非自己,而临床对照组的人往往因失败而自责。愤怒而非自尊与一种以指责他人而非自己为特征的归因偏差有关。
总之,愤怒是被害妄想研究中一种先前被忽视的情绪,值得进一步关注。这种情绪的指向他人的性质凸显了人际图式在理解偏执方面的潜在作用。
