In this paper we review a series of recent investigations into cognitive abnormalities associated with persecutory delusions. Studies indicate that persecutory delusions are associated with abnormal attention to threat-related stimuli, an explanatory bias towards attributing negative outcomes to external causes and biases in information processing relating to the self-concept. We propose an integrative model to account for these findings in which it is hypothesized that, in deluded patients, activation of self/ideal discrepancies by threat-related information triggers defensive explanatory biases, which have the function of reducing the self/ideal discrepancies but result in persecutory ideation. We conclude by discussing the implications of this model for the cognitive-behavioural treatment of paranoid delusions.
在本文中，我们回顾了一系列近期关于与被害妄想相关的认知异常的调查研究。研究表明，被害妄想与对威胁相关刺激的异常关注、将负面结果归因于外部原因的解释偏差以及与自我概念相关的信息处理偏差有关。我们提出了一个综合模型来解释这些发现，其中假设在患有妄想的患者中，与威胁相关的信息激活自我/理想差异会引发防御性解释偏差，这种偏差具有减少自我/理想差异的功能，但会导致被害观念。我们通过讨论该模型对偏执妄想的认知行为治疗的意义来结束本文。
