Background/AimThe Canadian Occupational Performance Measure (COPM) is a person-centered assessment tool frequently used to identify occupational problems in older individuals and establish goals for geriatric rehabilitation. This study aims to assess the validity and reliability of the Turkish version of COPM (COPM-TR) in older people.Materials And MethodsOne hundred older people completed the COPM-TR, and 25 of them participated in a retest within two weeks. The convergent construct validity analyses of the COPM-TR included conducting correlation analyses between the COPM-TR and the Functional Independence Measure (FIM) and Lawton Brody Instrumental Activities of Daily Living (Lawton-IADL) scales. The Performance and Satisfaction subscales were subjected to an item analysis for the internal consistency of the COPM-TR. A test-retest analysis was conducted to investigate the reliability.ResultsAccording to convergent construct validity analysis, it was found that there is a moderate correlation between COPM-TR performance and FIM (r = 0.51), and a strong correlation between Lawton IADL (r = 0.62). Similarly, there was a strong correlation between COPM-TR satisfaction and FIM (r = 0.61) and Lawton IADL (r = 0.61). Test-retest reliability was excellent for performance score and good for satisfaction score (ICC values 0.92; 0.78, respectively). COPM-TR showed excellent-high internal consistency (Cronbach's alpha 0.92 for performance and 0.88 for satisfaction).ConclusionCOPM-TR is a valid and reliable tool that can be used to assess occupational performance in older people.© TÜBİTAK.
