The Canadian Occupational Performance Measure (COPM) is receiving international attention as an important assessment for directing occupational therapy interventions and measuring client-centred outcomes. The COPM measures individuals' perceptions of disability by identifying those tasks that are important to them and difficult to perform. The Health Assessment Questionnaire (HAQ) has been used extensively with persons with arthritis and measures individuals' perceived difficulty in performing predetermined tasks of daily living. The HAQ has been shown to correlate with actual performance and has reported concurrent validity with a number of similar scales. In this study, 13 participants diagnosed with rheumatoid arthritis were assessed with the COPM and the disability dimension of the HAQ. Participants scored performance limitations on both the COPM and the HAQ; the correlation coefficient between the scores was not statistically significant. However, when the COPM and the HAQ scores for similar activities were compared, a statistically significant correlation was found. These findings support the use of the COPM as a valid measure of self-reported performance.
