Turkish validity and reliability of Canadian Occupational Performance Measure in children with Cerebral palsy and turkish translation of instructions

This study planned to evaluate the Canadian Occupational Performance Measure (COPM), which assesses the person-centered occupational performance, in children with Cerebral Palsy (CP) and translate its instructions into Turkish. The study included 76 children between the ages of 8-18 years, who scored 27 points or more on the Modified Mini Mental Test and were appropriate for levels 1 and 2 in the Communication Function Classification System. The translation procedure defined by Beaton was conducted. Validity of the COPM was tested with convergent and divergent construct validity analyses; and the COPM's reliability was tested with intrnal consistency and test-retest methods. For convergent construct validity, the correlation between the COPM and the Pediatric Disability Evaluation Inventory (PEDI) was examined and correlations were found in the social functions, self-care and mobility sub-headings. As a result of the divergent construct validity analysis, no significant difference was found between the performance and satisfaction scores of COPM between girls and boys (p=0.75, p=0.11) and it was found to be consistent according to gender. According to the results of the item analysis, Cronbach's alpha was between 0.60-0.79 and the internal consistency was found acceptable. The test-retest analysis for COPM yielded excellent reliability for time related equability for performance and satisfaction parameters (ICC>0,9). As a result, it was found that COPM is a valid-reliable measurement tool in children aged 8-18 years with CP. Children were assessed with the COPM in accordance with the instructions, and it was observed that the most frequently reported occupational areas were leisure, productivity and self-care, respectively. Studies in the literature administered the COPM with parents, and self-care activities were frequently reported as a problem. Further studies are needed on the benefit of administering the COPM to both the child and the parent separately and setting a common goal.
