Psychometric Evaluation of the Turkish Classification and Assessment of Occupational Dysfunction Scale

Occupational dysfunction affects daily life and well-being, requiring valid assessment tools. Cross-cultural adaptation ensures their applicability across populations. This study adapts the Classification and Assessment of Occupational Dysfunction into Turkish (CAOD-T) and evaluates its validity, reliability, psychometric evaluation and clinical compatibility. A total of 224 participants were recruited, including 179 individuals without disabilities and 45 individuals with physical disabilities. Construct validity was tested via confirmatory factor analysis (CFA). Known-groups validity compared scores between groups. Reliability was assessed using Cronbach's alpha, intraclass correlation coefficient (ICC), and McDonald's ω. Sensitivity and specificity were analyzed via receiver operating characteristic (ROC) analysis. CFA confirmed the four-factor structure (comparative fit index [CFI] = 0.934, root mean square error of approximation [RMSEA] = 0.0373). CAOD-T demonstrated strong internal consistency (α = .758), test-retest reliability (ICC = .756), and clinical compatibility (area under the curve [AUC] = 0.953, sensitivity = 93.3%, specificity = 91.11%). CAOD-T is a valid, reliable, and clinically applicable tool for assessing occupational dysfunction in Turkish populations. Future studies should explore its use across different age groups and cultures.
