Abstract：
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; Mage = 13.09 years), 1324 senior high school students (44.2% boys; Mage = 16.06 years), 812 undergraduate students (36.3% boys; Mage = 18.88 years), and 406 male adults from a general population (Mage = 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.
摘要：
临床损害评估（CIA）是用于评估与进食障碍（ED）相关的心理社会损害的最广泛使用的工具。根据标准程序将CIA翻译成中文。在四个青少年和成人样本中评估了ChineseCIA（C-CIA）的心理测量特性[即，792名初中生(47.0%男生;法师=13.09岁),1324名高中生（男孩占44.2%；法师=16.06岁），812名本科生（36.3%为男生；法师=18.88岁），和406名普通人群中的男性成年人（Mage=28.53岁）]。重复了CIA的三因素结构。C-CIA的内部一致性很好，α=0.93-0.98。C-CIA在六个月的时间间隔内对初中生（ICC=0.69）和高中生（ICC=0.76）显示出中等和良好的重测可靠性，分别。对于本科生（ICC=0.78）和普通成年男子（ICC=0.81），C-CIA在两周间隔内具有良好的重测可靠性。我们的结果支持良好的结构效度，中情局的已知群体有效性，以及性别和年龄之间的测量不变性。这些发现表明，C-CIA可以成为评估中国青少年与ED相关的心理社会损害的有用工具，年轻人,和成年男子。
