The Canadian Occupational Performance Measure (COPM) is an outcome measure created for occupational therapists to assess client outcomes in self-care, productivity, and leisure. Factors that interact with these three areas and affect occupational performance include a client's physical, socio-cultural, mental, and spiritual characteristics. The COPM was developed using client-centred practice guidelines of occupational therapy. The assessment was designed to help occupational therapists establish occupational performance goals based on client perceptions of need in defined problem areas. The COPM is administered using a five-step process:
Problem Definition: identify if there are any issues with occupational performance
Problem Weighting: rate the importance of each item on a 1-10 scale
Scoring: rate the ability to perform and satisfaction with performance using the same 1-10 scale
Re-assessment: later, at an appropriate time, rate the client's performance and satisfaction with performance for a second time. Compare these scores to evaluate change over time.
Follow-up: determine if there are further occupational performance issues to be addressed
