The Clinical Impairment Assessment (CIA) assesses psychosocial impairment secondary to an eating disorder. The aim of this study was to create and validate a Spanish-language version of the CIA. Using a forward-backward translation methodology, we translated the CIA into Spanish and evaluated its psychometric characteristics in a clinical sample of 178 ED patients. Cronbach's alpha values, confirmatory factor analysis (CFA), and correlations between the CIA and the Eating Attitudes Test-12 and the Health-Related Quality of Life in ED-short form questionnaires evaluated the reliability, construct validity, and convergent validity, respectively. Known-groups validity was also studied comparing the CIA according to different groups; responsiveness was assessed by means of effect sizes. Data revealed a three-factor structure similar to that of the original CIA. Cronbach alpha coefficient of 0.91 for the total CIA score supported its internal consistency and correlations with other instruments demonstrated convergent validity. The total CIA score and factor scores also significantly discriminated between employment status, evidencing known-groups validity. Responsiveness parameters showed moderate changes for patients with restrictive eating disorders. These findings suggest that the CIA can be reliably and validly used in Spain in a number of different clinical contexts, by researchers and clinicians alike.
临床损伤评估（CIA）评估进食障碍引起的心理社会损伤。本研究旨在创建并验证 CIA 的西班牙语版本。我们使用前后翻译方法将 CIA 翻译成西班牙语，并在 178 名 ED 患者的临床样本中评估其心理测量特性。Cronbach's alpha 值、验证性因素分析（CFA）以及 CIA 与饮食态度测试-12 和 ED 短式健康相关生活质量问卷之间的相关性分别评估了可靠性、结构有效性和收敛有效性。通过比较不同组别的 CIA 还研究了已知组别的有效性；通过效应大小评估了反应性。数据显示出与原始 CIA 相似的三因素结构。CIA 总分的 Cronbach alpha 系数为 0.91，支持其内部一致性，与其他工具的相关性表明了收敛有效性。CIA 总分和因子分数也能显著区分就业状况，表明了已知组别的有效性。反应性参数显示限制型饮食障碍患者有中等程度的变化。这些发现表明，CIA 可以在西班牙的许多不同临床环境中，由研究人员和临床医生可靠且有效地使用。
