Reliability and Validity of Bengali-Translated Child Occupational Self Assessment (BCOSA)

Abstract

Background: The Child Occupational Self-Assessment (COSA), a self-report of occupational competence and value for activities, may provide occupational therapists with a greater understanding of children’s occupational competence and values. The Bengali-Translated Child Occupational Self-Assessment (BCOSA) is a client-centered instrument designed to assess goal setting and intervention planning for children and youths with a client-centered approach in Bangladeshi context. Aim: This study aimed to assess the content validity, construct validity and internal consistency reliability of the Bengali-translated Child Occupational Self-Assessment (BCOSA). Methods: Adaptation and psychometric properties testing of the Bengali-COSA were conducted with 200 respondents after the translation phase. The content validity of the questionnaire was measured by expert opinion. Cronbach’s alpha statistical test was used to measure the internal consistency of the questionnaire, while the construct validity was measured using Pearson correlation coefficients test. Results: Content validity for all items of the questionnaire was >0.75. Cronbach’s alpha value of the COSA scale for competence .89 and value were .92 with high internal consistency. In Pearson correlation coefficient twenty-two items of the COSA competence were significantly (p<0.05) correlated with all competence items as well as most of the COSA value items were significantly (p<0.05) correlated with all value items. Conclusion: This study demonstrated that the Bengali version of COSA was highly valid, and reliable tool for use in client-centered goal setting and intervention planning for Bengali children and youths. Nonetheless, further research is warranted to conduct more comprehensive analyses that thoroughly assess the functions of the BCOSA in various contexts
