两组患有迫害妄想症的患者，一组由也患有抑郁症的患者组成，另一组由非抑郁组组成，以及在年龄和智力上与被妄想者匹配的临床抑郁症和正常对照组，他们被要求评估选定的积极、消极和中性事件在过去发生在自己和普通其他人身上的频率，以及这些事件在未来可能发生在自己和普通其他人身上的频率。过去和预期的未来事件的结果都是相似的。与正常对照组相比，非抑郁-妄想、抑郁-妄想和抑郁患者被评为发生负面事件的频率相对更高。抑郁的参与者认为积极事件发生在别人身上的频率更高，而正常参与者认为负面事件发生在其他人身上的频率更高。相关分析表明，抑郁得分与对自我正面事件发生频率的低估计和对负面事件发生频率的高估计有关。魔力思维得分是精神病的一个指标，它与对自己和他人的负面事件频率的高估计有关。这些发现是在先前关于妄想症患者认知偏差的证据的背景下解释的。
Two groups of patients suffering from persecutory delusions, one consisting of patients also suffering from depression and a non-depressed group, together with clinically depressed and normal controls matched with the deluded patients for age and intelligence, were asked to rate the frequency with which selected positive, negative and neutral events had happened to themselves and to an average other person in the past, and the frequency with which these events were likely to happen to themselves and to an average other person in the future. Results were similar for both past and expected future events. Non-depressed-deluded, depressed-deluded and depressed patients rated negative events as occurring relatively more frequently in comparison to the normal controls. Depressed participants rated positive events as occurring more frequently to others, whereas the normal participants rated negative events as occurring more often to others. Correlational analyses indicated that depression scores were associated with low estimates of the frequency with which positive events happen to self and high estimates of the frequency with which negative events happen to self. Magical ideation scores, an index of psychosis, were associated with high estimates of the frequency of negative events for both self and others. These findings are interpreted in the context of previous evidence on cognitive biases in deluded patients.
