Over the last few decades, research concerning the insight of patients with schizophrenia and its relationships with other clinical variables has been given much attention in the clinical setting. Since that time, a series of instruments assessing insight have been developed. The purpose of this study was to examine the reliability and validity of the Taiwanese version of the Beck Cognitive Insight Scale (BCIS). The BCIS is a self-administered instrument designed to evaluate cognitive processes that involves reevaluating patients' anomalous experiences and specific misinterpretations.
The English language version of the BCIS was translated into Taiwanese for use in this study. A total of 180 subjects with and without psychosis completed the Taiwanese version of the BCIS and additional evaluations to assess researcher-rated insight scales and psychopathology. Psychometric properties (factor structures and various types of reliability and validity) were assessed for this translated questionnaire.
Overall, the Taiwanese version of the BCIS showed good reliability and stability over time. This translated scale comprised a two-factor solution corresponding to reflective attitude and certain attitude subscales. Following the validation of the internal structure of the scale, we obtained an R-C (reflective attitude minus certain attitude) index of the translated BCIS, representing the measurement of cognitive insight by subtracting the score of the certain attitude subscale from that of the reflective attitude subscale. As predicted, the differences in mean reflective attitude, certain attitude and R-C index between subjects with and without psychosis were significant. Our data also demonstrated that psychotic patients were significantly less reflective, more confident in their beliefs, and had less cognitive insight compared with nonpsychotic control groups.
In light of these findings, we believe that the Taiwanese version of BCIS is a valid and reliable instrument for the assessment of cognitive insight in psychotic patients.
在过去几十年中,对精神分裂症患者洞察力及其与其他临床变量关系的研究在临床环境中受到了广泛关注。从那时起,已经开发出一系列评估洞察力的工具。本研究旨在检验台湾版贝克认知洞察力量表(BCIS)的信度和效度。BCIS 是一种自我管理的工具,旨在评估涉及重新评估患者异常体验和特定误解的认知过程。
将 BCIS 的英文版本翻译成中文,用于本研究。共有 180 名有和没有精神病的患者完成了台湾版的 BCIS 以及其他评估,以评估研究人员评定的洞察力量表和精神病理学。评估了该翻译问卷的心理测量特性(因素结构和各种类型的信度和效度)。
总体而言,台湾版的 BCIS 表现出良好的信度和时间稳定性。该翻译量表由反映态度和某些态度子量表的两个因素组成。在验证量表的内部结构后,我们获得了翻译 BCIS 的 R-C(反映态度减去某些态度)指数,通过从反映态度子量表的分数中减去某些态度子量表的分数来表示认知洞察力的测量。正如预测的那样,有和没有精神病的患者之间的平均反映态度、某些态度和 R-C 指数的差异具有统计学意义。我们的数据还表明,与非精神病对照组相比,精神病患者的反映性明显降低,对自己的信念更有信心,认知洞察力也更低。
鉴于这些发现,我们认为台湾版的 BCIS 是评估精神病患者认知洞察力的有效且可靠的工具。
