The Clinical Impairment Assessment (CIA) is a measure of functional impairment secondary to eating disorder symptoms.
The aim of this study was to examine the psychometric proprieties of the Italian-language version of the CIA.
The tool was translated into Italian and administered to 259 Italian-speaking in- and outpatients with eating disorders and 102 healthy controls. The clinical group also completed the Eating Disorder Examination Questionnaire (EDE-Q) and the Brief Symptom Inventory (BSI).
Confirmatory factor analysis revealed a good fit for the original three-factor structure. Internal consistency was high for both the global CIA and all subscale scores, and test-retest reliability was acceptable. The high correlation between CIA and EDE-Q and BSI confirmed the convergent validity of the instrument. T test indicated higher raw scores on CIA in patients with eating disorders than healthy controls, and a cut-off score of 16 on the CIA discriminated between eating disorder and general psychopathology scores. Finally, global CIA and subscale scores were significantly higher in patients who reported objective bulimic episodes, purging behaviours, and excessive exercising than in those who did not; in underweight than in not-underweight patients, and in inpatients than outpatients, confirming the good known-groups validity of the tool.
Overall, the study showed the good psychometric properties of the Italian version of the CIA, and validated its use in Italian-speaking eating disorder patients.
Level V, Descriptive study.
临床损害评估（CIA）是一种衡量饮食失调症状继发功能损害的方法。
本研究旨在检验意大利语版CIA的心理测量学特性。
该工具被翻译成意大利语，并应用于259名讲意大利语的饮食失调门诊和住院患者以及102名健康对照者。临床组还完成了饮食失调检查问卷（EDE-Q）和简明症状量表（BSI）。
验证性因素分析显示与原始三因素结构拟合良好。CIA总分及所有子量表得分的内部一致性较高，重测信度可接受。CIA与EDE-Q和BSI之间的高相关性证实了该工具的收敛效度。t检验表明，饮食失调患者的CIA原始得分高于健康对照者，CIA得分16可区分饮食失调和一般精神病理学得分。最后，报告有客观暴食发作、清除行为和过度运动的患者的CIA总分及子量表得分显著高于未出现这些情况的患者；体重过轻患者高于非体重过轻患者，住院患者高于门诊患者，证实了该工具良好的已知组效度。
总体而言，该研究表明意大利语版CIA具有良好的心理测量学特性，并验证了其在讲意大利语的饮食失调患者中的应用。
