Although previous research demonstrates that clinical individuals with delusions score low on one of the facets of cognitive insight, self-reflection, and high on the other facet, self-certainty, analogous studies of delusion proneness in nonclinical individuals have found that delusion proneness in nonclinical individuals associates with higher levels of both self-certainty and self-reflection. The present study sought to reconcile these inconsistent results by examining the contributions of different facets of self-reflection, rumination and reflection, to delusion proneness. One hundred fifty-two individuals completed three questionnaires: the Beck Cognitive Insight Scale (BCIS), the Peters et al. Delusions Inventory (PDI), and the Rumination-Reflection Questionnaire (RRQ). The results showed that the individuals scoring higher on delusion proneness demonstrated higher levels of both self-certainty and self-reflection on the BCIS as well as higher levels of rumination and reflection on the RRQ. As predicted, the strength of the relationship between BCIS self-reflection and delusion proneness was diminished when rumination was controlled for. These findings suggest that the previously observed positive relation between BCIS self-reflection and nonclinical delusion proneness might be driven, in part, by the ruminative aspect of self-reflection.
尽管先前的研究表明，有妄想的临床个体在认知洞察力的一个方面（自我反思）得分较低，而在另一个方面（自我确定性）得分较高，但对非临床个体的妄想倾向进行的类似研究发现，非临床个体的妄想倾向与更高水平的自我确定性和自我反思相关。本研究试图通过考察自我反思的不同方面（沉思和思考）对妄想倾向的影响来调和这些不一致的结果。152名个体完成了三份问卷：贝克认知洞察力量表（BCIS）、彼得斯等人的妄想量表（PDI）以及沉思-思考问卷（RRQ）。结果显示，在妄想倾向方面得分较高的个体在BCIS上表现出更高水平的自我确定性和自我反思，以及在RRQ上表现出更高水平的沉思和思考。正如预期的那样，当控制了沉思因素后，BCIS自我反思与妄想倾向之间的关系强度减弱。这些发现表明，先前观察到的BCIS自我反思与非临床妄想倾向之间的正相关关系可能部分是由自我反思的沉思方面驱动的。
