The present study investigated the relationship between delusion proneness, as assessed using the Peters et al. Delusions Inventory [Peters, E.R., Joseph, S.A., Garety, P.A., 1999. The measurement of delusional ideation in the normal population: Introducing the PDI (Peters et al. Delusions Inventory). Schizophr. Bull. 25 553-576], and cognitive insight, as assessed using the Beck Cognitive Insight Scale (BCIS; [Beck, A.T., Baruch, E., Balter, J.M., Steer, R.A., Warman, D.M., 2004. A new instrument for measuring insight: The Beck Cognitive Insight Scale. Schizophr. Res. 68, 319-329]. Two hundred undergraduate students with no history of psychotic disorder participated. Results indicated that, consistent with hypotheses, those higher in delusion proneness endorsed more certainty in their beliefs and judgment than those who were lower in delusion proneness (Self-Certainty subscale of the BCIS; p = .007). Contrary to hypotheses, however, those who were higher in delusion proneness were more open to external feedback and were more willing to acknowledge fallibility than those who were lower in delusion proneness (Self-Reflectiveness subscale of the BCIS; p = .002). The results are discussed in relation to theories of delusion formation.
本研究调查了使用彼得斯等人的妄想量表（彼得斯、约瑟夫、加雷蒂，1999年。正常人群中妄想观念的测量：介绍PDI（彼得斯等人的妄想量表）。《精神分裂症通报》25 553 - 576）评估的妄想倾向与使用贝克认知洞察力量表（BCIS；贝克、巴鲁克、巴尔特、斯蒂尔、沃曼，2004年。一种测量洞察力的新工具：贝克认知洞察力量表。《精神分裂症研究》68，319 - 329）评估的认知洞察力之间的关系。200名无精神障碍病史的本科生参与了研究。结果表明，与假设一致，妄想倾向较高的人在信念和判断上比妄想倾向较低的人更确定（BCIS的自我确定性子量表；p = 0.007）。然而，与假设相反，妄想倾向较高的人比妄想倾向较低的人更愿意接受外部反馈，也更愿意承认自己可能犯错（BCIS的自我反思子量表；p = 0.002）。研究结果结合妄想形成理论进行了讨论。
