Measurement of disease-related impairment and distress is central to diagnostic, therapeutic, and health policy considerations for eating disorders across diverse populations. This study evaluates psychometric properties of a translated and adapted version of the Clinical Impairment Assessment (CIA) in an ethnic Fijian population.
The adapted CIA was administered to ethnic Fijian adolescent schoolgirls (N = 215). We calculated Cronbach's alpha to assess the internal consistency, examined the association between indicators of eating disorder symptom severity and the CIA to assess construct and criterion validity, and compared the strength of relation between the CIA and measures of disordered eating versus with measures of generalized distress.
The Fijian version of the CIA is feasible to administer as an investigator-based interview. It has excellent internal consistency (alpha = 0.93). Both construct and criterion validity were supported by the data, and regression models indicated that the CIA predicts eating disorder severity, even when controlling for generalized distress and psychopathology.
The adapted CIA has excellent psychometric properties in this Fijian study population. Findings suggest that the CIA can be successfully adapted for use in a non-Western study population and that at least some associated distress and impairment transcends cultural differences.
衡量疾病相关的损伤和痛苦是跨人群诊断、治疗和健康政策考虑进食障碍的核心。本研究评估了经翻译和改编的临床损伤评估（CIA）在斐济族群青少年女性中的心理测量学特性。
适应性 CIA 被用于斐济族群青少年女性（N=215）。我们计算了克朗巴赫 α 以评估内部一致性，检验了饮食障碍症状严重程度指标与 CIA 之间的关联以评估结构和标准效度，并比较了 CIA 与饮食紊乱测量指标之间的关系强度与广义困扰测量指标之间的关系强度。
CIA 的斐济版本作为一种基于调查员的访谈是可行的。它具有极好的内部一致性（α=0.93）。数据支持结构和标准效度，回归模型表明 CIA 可以预测饮食障碍的严重程度，即使在控制广义困扰和精神病理学时也是如此。
适应性 CIA 在这项斐济研究人群中具有极好的心理测量学特性。研究结果表明，CIA 可以成功地适应于非西方研究人群，并且至少一些相关的痛苦和损伤超越了文化差异。
