Cognitive biases are recognized as important treatment targets for reducing symptoms associated with severe mental disorders. Although cognitive biases have been linked to symptoms in most studies, few studies have looked at such biases transdiagnostically. The Cognitive Bias Questionnaire for psychosis (CBQp) is a self-reported questionnaire that assesses cognitive biases amongst individuals with a psychotic disorder, as well as individuals with other severe mental disorders. The current study aims to validate a French version of the CBQp and to explore transdiagnostic cognitive biases in individuals with psychotic disorders, individuals with depression, and in healthy controls.
The CBQp was translated into French following a protocol based on international standards. Discriminant validity and internal consistency were determined for total score and each subscale score. Confirmatory factor analyses were performed to test construct validity. Finally, cluster analyses were conducted to investigate cognitive biases across diagnostic groups.
Our results were similar to those of the original authors, with the one-factor solution (assessment of a general thinking bias) being the strongest, but the two-factor solution (assessing biases within two themes relating to psychosis) and the five-factor solution (assessment of multiple distinct biases) being clinically more interesting. A six-cluster solution emerged, suggesting that individuals with similar diagnoses score differently on all cognitive biases, and that individuals with different diagnoses might have similar cognitive biases.
The current findings support the validity of the French translation of the CBQp. Our cluster analyses overall support the transdiagnostic presence of cognitive biases.
认知偏差被认为是减少与严重精神障碍相关症状的重要治疗目标。尽管大多数研究都表明认知偏差与症状有关，但很少有研究从跨诊断的角度研究这些偏差。认知偏向问卷精神病版（CBQp）是一种自我报告的问卷，用于评估精神障碍患者以及其他严重精神障碍患者的认知偏差。本研究旨在验证 CBQp 的法语版本，并探讨精神障碍患者、抑郁症患者和健康对照组之间的跨诊断认知偏差。
根据基于国际标准的协议，将 CBQp 翻译成法语。对总分和各分量表得分进行判别有效性和内部一致性检验。进行验证性因子分析以检验结构有效性。最后，进行聚类分析以研究跨诊断组的认知偏差。
我们的结果与原始作者的结果相似，单因素解决方案（评估一般思维偏差）最强，但双因素解决方案（评估与精神病相关的两个主题中的偏差）和五因素解决方案（评估多个不同的偏差）在临床上更有趣。出现了一个六聚类解决方案，表明具有相似诊断的个体在所有认知偏差上的得分不同，而具有不同诊断的个体可能具有相似的认知偏差。
本研究结果支持 CBQp 法语翻译的有效性。我们的聚类分析总体上支持认知偏差的跨诊断存在。
