Purpose: Although some studies have been conducted to examine general psychosocial impairment in Iran, there is no research to date on clinical impairment secondary to disordered eating in Iranian adolescents. The purpose of this study was to evaluate the Farsi version of the Clinical Impairment Assessment (F-CIA) among Iranian adolescents. Methods: A total of 1112 adolescents (ageM [SD] = 15.55 [1.59], body mass index [zBMI] M [SD] = – 0.00 [1.0]; 54.6% girls) were recruited from four cities (Tehran [Capital], Tabriz [North-Western], Kurdistan [West], and Rasht [North]) in Iran. After translation and back-translation procedures, the F-CIA, Eating Disorder Examination Questionnaire (EDE-Q), and Beck Depression Inventory-Second Edition (BDI-II) were administered to adolescents. We used confirmatory factor analysis (CFA), measurement invariance, independent samples t tests, Pearson correlation, chi-square tests, and internal consistency to test validity and reliability. Results: CFA indicated that F-CIA demonstrated good fit to the data and supported a three-factor model. The scale was invariant across gender and zBMI. The F-CIA had good internal consistency (αs = 0.76–0.93) and positive associations (rs = 0.13–0.62; p < 0.001) with zBMI, disordered eating symptoms, and binge/purge symptoms. We found no gender differences across mean scores on the F-CIA, but adolescents with higher zBMI reported higher scores on the F-CIA relative to those with lower zBMIs. Finally, adolescents scoring above CIA cutoffs reported higher zBMI, disordered eating outcomes, and depression. Conclusion: Findings suggested that the F-CIA is a reliable and valid measure of clinical eating disorder-related impairment in Iranian adolescents. Level of evidence: III; Evidence obtained from well-designed observational study, including case–control design for relevant aspects of the study.
