The Clinical Impairment Assessment (CIA 3.0) is the most widely used instrument assessing psychosocial impairment secondary to eating disorder symptoms. However, there is conflicting advice regarding the dimensionality and optimal method of scoring the CIA. We sought to resolve this confusion by conducting a comprehensive factor analytic study of the CIA in a community sample ( = 301) and clinical sample comprising patients with a diagnosed eating disorder ( = 209). Convergent and discriminant validity were also assessed. The CIA and measures of eating disorder symptoms were administered to both samples. Factor analyses indicated there is a general impairment factor underlying all items on the CIA that is reliably measured by the CIA Global score. CIA Global demonstrated good convergent and discriminant validity. CIA Global is a reliable and valid measure of psychosocial impairment secondary to eating disorder symptoms; however, subscale scores should not be computed.
临床损伤评估（CIA3.0）是评估因饮食障碍症状导致的心理社会损伤最常用的工具。然而，关于 CIA 的维度和最佳评分方法存在相互矛盾的建议。我们通过对一个社区样本（n=301）和一个包含已确诊饮食障碍患者的临床样本（n=209）进行全面的因子分析研究，旨在解决这一困惑。还评估了收敛和判别效度。CIA 和饮食障碍症状的测量方法均应用于两个样本。因子分析表明，CIA 上所有项目的背后都有一个一般的损伤因素，该因素可由 CIA 总得分可靠地测量。CIA 总得分表现出良好的收敛和判别效度。CIA 总得分是评估因饮食障碍症状导致的心理社会损伤的可靠且有效的工具；然而，不应该计算子量表得分。
