Canadian Occupational Performance Measure (COPM)

Download Clinical Summary PDF

Tool Description:

The Canadian Occupational Performance Measure (COPM) is a clinician-administered interview style questionnaire which measures the client’s self-perception of occupational performance.
The client is asked to identify a number of activities of difficulty. Then, the client rates their perceived performance, importance, and satisfaction regarding each activity on a 1-10 scale. It is recommended to administer the COPM multiple times in order to determine changes in scores over time.

Measurement Property Summary:

# of studies reporting psychometric properties: 3

Reliability:

  • Test-retest reliability of the COPM is High for performance (ICC=0.99) and satisfaction subscales (ICC=0.98).
  • Internal consistency of the COPM is High for performance (alpha=0.93) and satisfaction subscales (alpha=0.89).

[Beradi et al. 2019]

Validity:

  • There is Moderate correlation with the COPM subscales and the Functional Independence Measure (FIM) Motor subscale (r=0.388-0.514).
  • There is Low correlation with the COPM subscales and the Klein-Bell ADL Scale (rho=0.07) and the SCIM III (r=0.22-0.30, rho=0.17-0.30).
