Psychometric Validation of Turkish Assessment of Positive Occupation-15 in Individuals with Schizophrenia

Positive occupational engagement supports mental health and well-being in individuals with schizophrenia, yet few standardized tools assess this construct. To adapt and psychometrically validate the Turkish version of the Assessment of Positive Occupation-15 (APO-15) in schizophrenia. A methodological study was conducted with 263 participants (97 with schizophrenia, 166 healthy adults). Cross-cultural adaptation followed standard procedures. Confirmatory factor analysis (CFA), internal consistency (Cronbach's α), test-retest reliability, and correlations with the Recovery Assessment Scale (RAS) and Motivational Persistence Scale (MPS) were. CFA supported a four-factor structure with acceptable fit. The scale showed strong internal consistency (α = .818) and excellent test-retest reliability (ICC = .814). APO-15 scores correlated moderately with RAS and MPS. Receiver Operating Characteristic (ROC) analysis identified a cut-off score of 47.5. The Turkish APO-15 is a valid and reliable tool for assessing positive occupational engagement in schizophrenia and can inform occupational therapy interventions.
