Psychometric properties of the Bengali-Translated Occupational Self-Assessment Short Form

Introduction: The Occupational Self-Assessment-Short Form (OSA-SF) is a client-centered instrument designed to assess goal setting and intervention planning for adults with a client-centered approach. This study aimed to assess the psychometric properties of the Bengali-translated Occupational Self-Assessment-Short Form (BOSA-SF), which could enable occupational therapists to evaluate the occupational competence and value of Bengali adults. Method: A total of 170 adult participants participated in the study after the translation phase. The data were analyzed using confirmatory factor analysis and Rasch analysis. Results: Among the 12 items, 11 on the competence scale and all 12 on the value scale were unidimensional and demonstrated local independence. The 11 competence items and 12 value items were fitted to the Rasch model, demonstrating good validity and reliability. Conclusion: The 11-item BOSA-SF demonstrates to be a valid and reliable tool for use in client-centered goal setting and intervention planning for Bengali adults. Nonetheless, further research is warranted to conduct more comprehensive analyses that thoroughly assess the functions of the BOSA-SF in various contexts.
