The Clinical Impairment Assessment questionnaire (CIA) is used to measure the severity of psychosocial impairment in patients with eating disorders. The purpose of the present study was to develop a new Japanese version of the CIA (CIA-J) and to evaluate its reliability and validity.
We translated the sixteen items of the CIA into Japanese, back-translated them into English, and had them verified by a native English speaking professional editor. Participants were 152 Japanese-speaking patients (30.4 ± 10.6 years) under treatment for eating disorders and 173 healthy controls (29.5 ± 8.3 years). In addition to the CIA-J, the participants were asked to answer the Eating Attitudes Test (EAT26), The Positive and Negative Affect Schedule (PANAS), and the Hospital Anxiety and Depression Scale (HADS). We performed confirmatory factor analyses to evaluate the factor structure, calculated the Cronbach's alphas of the CIA-J to assess the reliability, and calculated the correlation coefficients between the CIA-J score and those of EAT26, PANAS, and HADS to assess concurrent validity. We also used a Kruskal-Wallis test followed by Steel-Dwass test to compare the scores of the subtypes of eating disorders and the healthy control group.
A three-factor structure was obtained, similar to the original version. The Cronbach's alphas of both the global and subscale scores of the CIA-J were high. The CIA-J had significant positive correlations with the EAT26, the negative affect subscale of the PANAS, and the HADS. The global and subscale scores for all subtypes of eating disorders were significantly higher than those of the healthy control group.
The CIA-J was determined to be reliable and valid for assessing the severity of psychosocial impairment in patients with eating disorders.
临床损害评估问卷（CIA）用于测量饮食失调患者心理社会损害的严重程度。本研究的目的是开发CIA的新日语版本（CIA-J）并评估其信度和效度。
我们将CIA的16个项目翻译成日语，再回译成英语，并由以英语为母语的专业编辑进行审核。参与者为152名接受饮食失调治疗的日语患者（30.4±10.6岁）和173名健康对照者（29.5±8.3岁）。除了CIA-J，还要求参与者回答饮食态度测试（EAT26）、正负性情绪量表（PANAS）和医院焦虑抑郁量表（HADS）。我们进行验证性因素分析以评估因素结构，计算CIA-J的克朗巴哈系数以评估信度，并计算CIA-J得分与EAT26、PANAS和HADS得分之间的相关系数以评估同时效度。我们还使用Kruskal-Wallis检验，随后进行Steel-Dwass检验，以比较饮食失调亚型和健康对照组的得分。
获得了与原始版本相似的三因素结构。CIA-J的总体得分和分量表得分的克朗巴哈系数都很高。CIA-J与EAT26、PANAS的负性情绪分量表和HADS均呈显著正相关。所有饮食失调亚型的总体得分和分量表得分均显著高于健康对照组。
CIA-J被确定为评估饮食失调患者心理社会损害严重程度的可靠且有效的工具。
