The Clinical Impairment Assessment (CIA) is the most widely used instrument for assessing psychosocial impairment related to eating disorders (EDs). The CIA was translated into Chinese based on standard procedures. The psychometric properties of the Chinese CIA (C-CIA) were assessed among four adolescent and adult samples [i.e., 792 junior high school students (47.0% boys; M = 13.09 years), 1324 senior high school students (44.2% boys; M = 16.06 years), 812 undergraduate students (36.3% boys; M = 18.88 years), and 406 male adults from a general population (M = 28.53 years)]. The three-factor structure of the CIA was replicated. Excellent internal consistencies of the C-CIA were revealed, α = 0.93-0.98. The C-CIA showed moderate and good test-retest reliability in a six-month interval for junior high school students (ICC = 0.69) and senior high school students (ICC = 0.76), respectively. The C-CIA had good test-retest reliability in a two-week interval for undergraduate students (ICC = 0.78) and general adult men (ICC = 0.81). Our results supported good construct validity, known-group validity of the C-CIA, and measurement invariance across sex and age. These findings suggest that the C-CIA can be a useful tool assessing psychosocial impairment related to EDs for Chinese adolescents, young adults, and adult men.
临床损伤评估（CIA）是评估与饮食障碍（ED）相关的心理社会损伤最广泛使用的工具。CIA 根据标准程序被翻译成中文。在四个青少年和成年样本中评估了中文 CIA（C-CIA）的心理测量特性[即 792 名初中生（47.0%为男生；M=13.09 岁），1324 名高中生（44.2%为男生；M=16.06 岁），812 名本科生（36.3%为男生；M=18.88 岁）和 406 名来自普通人群的成年男性（M=28.53 岁）]。CIA 的三因素结构得到了复制。C-CIA 显示出优秀的内部一致性，α=0.93-0.98。在六个月的间隔内，初中生（ICC=0.69）和高中生（ICC=0.76）的 C-CIA 具有中等和良好的重测信度。在两周的间隔内，本科生（ICC=0.78）和普通成年男性（ICC=0.81）的 C-CIA 具有良好的重测信度。我们的结果支持 C-CIA 的良好结构效度、已知群体效度以及性别和年龄的测量不变性。这些发现表明，C-CIA 可以成为评估中国青少年、年轻成年人和成年男性与 ED 相关的心理社会损伤的有用工具。
