To research test-retest reliability and discriminant validity of the Canadian Occupational Performance Measure (COPM), a client-centred outcome measure, in stroke patients.
The COPM was administered twice with a mean interval of eight days (SD 2.5, range 5-16). On both occasions the patient identified a maximum of five problems in daily activities. The problems of both interviews were compared. The problems identified during the first COPM were rated by the patient on a performance and satisfaction rating scale on both occasions. The individually identified items with use of the client-centred COPM were compared with the fixed items of standardized measures (Barthel Index, Frenchay Activities Index, Stroke Adapted Sickness Impact Profile-30, Euroqol 5D and Rankin Scale).
Patients were interviewed at their place of residence.
Twenty-six stroke patients participated, 11 men and 15 women, aged from 26 to 83 years (mean 68, SD 15). Twenty-four patients were six months, two patients were two months post stroke.
Of the 115 problems identified during the first COPM, 64 (56%) were also identified the second time. Correlation coefficients for the scores were 0.89 (p
