The Cognitions About Body and Health Questionnaire (CABAH) is a self-rating questionnaire measuring cognitions about health. The psychometric properties of its Chinese version and its performance on evaluating somatic symptom disorder (SSD) were examined in this study.
After translating the CABAH into Chinese, we collected data of the CABAH and another four questionnaires (Patient Health Questionnaire-15, Health Anxiety Questionnaire, Beck Depression Inventory-II, Beck Anxiety Inventory) in 208 SSD patients and 197 healthy individuals. We used exploratory factor analysis (EFA) to explore the structure of the Chinese CABAH. Internal consistency and criterion-related validity were analyzed. An independent -test and receiver operating characteristic (ROC) curve analysis were used to evaluate the performance of the CABAH for evaluating SSD.
Six factors were suggested by EFA. Five (bodily weakness, health habits, catastrophizing interpretation of specific bodily complaints, somatosensory amplification, catastrophizing interpretation of general bodily complaints) are conceptually associated with the original CABAH. The sixth factor (reverse, with three items) is different from the original construct. Cronbach's alpha for the CABAH was 0.885. The CABAH score was moderately correlated with scores of the other four questionnaires. Scores for the whole CABAH and scores of the six factors were all significantly higher in SSD patients than in healthy individuals. The results of ROC curve analysis were as follows: area under the curve=0.700; suggested cutoff=58/59; Youden's =0.295.
The reliability and validity of the Chinese CABAH were fair, although the three items in the reverse factor should be interpreted cautiously.
身体与健康认知问卷（CABAH）是一种用于测量健康认知的自评问卷。本研究考察了其中文版的心理测量特性及其在评估躯体症状障碍（SSD）方面的表现。
将CABAH翻译成中文后，我们收集了208例SSD患者和197名健康个体的CABAH数据以及另外四份问卷（患者健康问卷-15、健康焦虑问卷、贝克抑郁量表第二版、贝克焦虑量表）的数据。我们使用探索性因素分析（EFA）来探索中文版CABAH的结构。分析了内部一致性和效标关联效度。采用独立样本t检验和受试者工作特征（ROC）曲线分析来评估CABAH评估SSD的表现。
EFA提出了六个因素。其中五个因素（身体虚弱、健康习惯、对特定身体不适的灾难化解释、体感放大、对一般身体不适的灾难化解释）在概念上与原始的CABAH相关。第六个因素（反向，包含三个项目）与原始结构不同。CABAH的Cronbach's α系数为0.885。CABAH得分与其他四份问卷的得分呈中度相关。SSD患者的CABAH总分及六个因素的得分均显著高于健康个体。ROC曲线分析结果如下：曲线下面积=0.700；建议的截断值=58/59；约登指数=0.295。
中文版CABAH的信效度尚可，尽管反向因素中的三个项目应谨慎解释。
