Validity and Reliability of the Turkish Canadian Occupational Performance Measure (COPM-TR) for People with Multiple Sclerosis.

The Canadian Occupational Performance Measure (COPM) is a generic questionnaire based on a semi-structured interview. We aimed to translate a Turkish version of the COPM (COPM-TR) and assess its reliability and validity. The COPM-TR was administered to 82 participants (42.2 ± 11.6 years and 32.9% of the participants were male) with multiple sclerosis (MS) for convergent validity and reliability analysis. The COPM-TR was administered with the Multiple Sclerosis Quality of Life-54 (MSQoL-54), and Expanded Disability Status Scale (EDSS) to determine its convergent validity. Test-retest reliability (a week interval) was assessed by the Intraclass Correlation Coefficient (ICC). There were moderately strong negative correlations between EDSS and performance and satisfaction score of COPM-TR. There were moderately strong positive correlations between MSQoL-54 physical and performance of COPM-TR and moderate positive correlations between MSQoL-54 physical and satisfaction of COPM-TR. Moderate positive correlations found between the MSQoL-54 mental and COPM-TR performance and satisfaction scores. Test re-test reliability of COPM-TR performance indicated excellent reliability. The current study demonstrates that the COPM-TR is a valid and reliable tool for measuring the perceived occupational performance and satisfaction of people with MS.
