Current models of paranoia propose that ambiguous situations, in which cues regarding the intentions of others are lacking, may be perceived as hostile by persons with persecutory delusions (PD). Thus, a social-cognitive bias for the perception of hostility may be present. In this study, the Ambiguous Intentions Hostility Questionnaire (AIHQ) was used to present situations that are ambiguous regarding the intentions of others. It was predicted that on the AIHQ, persons with PD would show greater levels of perceived hostility, blame, and aggression than both psychiatric and nonpsychiatric controls.
The sample comprised 32 persons with PD, 28 persons without PD (psychiatric controls), and 50 healthy participants (nonpsychiatric controls). Participants completed the AIHQ along with measures of paranoia, attributional style, depression, anxiety, self-esteem, and public self-consciousness.
As predicted, the group with PD showed greater perceptions of hostility, blame, and aggression scores for ambiguous situations on the AIHQ. Also, the AIHQ Hostility bias score was predictive of paranoid ideation.
Persons with PD showed a social-cognitive bias for perceiving hostility in ambiguous situations. The bias appears to be specific as it was not found in the psychiatric or nonpsychiatric control groups. Suggestions for future research are discussed.
当前的偏执狂模型认为，在缺乏有关他人意图线索的模糊情境中，患有被害妄想症（PD）的人可能会将其视为怀有敌意。因此，可能存在一种对敌意感知的社会认知偏差。在本研究中，使用了模糊意图敌意问卷（AIHQ）来呈现关于他人意图模糊的情境。预计在AIHQ上，患有PD的人会比精神科和非精神科对照组表现出更高水平的感知敌意、责备和攻击性。
样本包括32名患有PD的人、28名无PD的人（精神科对照组）和50名健康参与者（非精神科对照组）。参与者完成了AIHQ以及偏执狂、归因方式、抑郁、焦虑、自尊和公众自我意识的测量。
正如预期的那样，患有PD的组在AIHQ上对模糊情境表现出更高的敌意、责备和攻击性得分。此外，AIHQ敌意偏差得分可预测偏执观念。
患有PD的人在模糊情境中表现出对敌意感知的社会认知偏差。这种偏差似乎是特定的，因为在精神科或非精神科对照组中未发现。讨论了未来研究的建议。
