Canadian Occupational Performance Measure (COPM)

Description: A standardized measure of self-perception of occupational performance [1].

Format:  The COPM is an individualized measure that is administered via semi-structured interview. This measure is used to help respondents identify areas of difficulty in self-care, productivity, and leisure. Following identification of up to 5 problem areas, respondents rate each on a scale from 1 (least important) to 10 (most important). Respondents also rate their current level of performance and satisfaction with their performance in each of the 5 areas on a scale from 1 (with great difficulty or not satisfied) to 10 (with no difficulties or completely satisfied). On re-assessment, respondents review their goals and again rate their performance and satisfaction on the goals identified in the initial assessment.

Scoring: Mean scores are obtained for satisfaction and performance with scores ranging from 1 to 10. A change score is obtained by subtracting the post-treatment score from the initial score. The most meaningful scores derived from this assessment are the change scores between assessment and reassessment.

Administration and Burden: Interviewer-administered.

Psychometrics for SCI: Not available.

Languages: The COPM has been used in more than 35 countries and has been translated into over 20 languages.

QoL Concept: The COPM is a measure of Instrumental Activities of Daily Living, which corresponds to Boxes C (achievements) and D (individual expectations and priorities; impact on activities), and E (subjective evaluations and reactions) of Dijker’s Model.
