The Canadian Occupational Performance Measure (COPM) is used to assess clients' perceived performance of daily activities and their satisfaction with their performance. This study gathered evidence on the content-related and criterion-related validity of the instrument. Thirty-nine adult clients with orthopaedic and stroke disabilities were assessed using the COPM as well as three criterion instruments. Nine individuals with expertise in clinical practices and measurement participated in a panel review to evaluate the test content of the COPM. Results suggested that the assessment content and processes reflected clients' occupational performance issues. Criterion-related validity between the COPM and Functional Independence Measure was (r = -0.14 to 0.38), and with the Satisfaction with Performance Scaled Questionnaire was (r = -0.13 to 0.40). Evidence gathered indicated the methods and importance of vigorously testing the appropriateness and meaningfulness of this clinical outcome measure. Further research should be directed at improving the standardization and clinical application of the COPM. 1997
