Validity and community utility of the Canadian Occupational Performance Measure.
This study addressed the validity and community utility of the Canadian Occupational Performance Measure (COPM) (Law et al., 1991; 1994; 1998): a measure that now represents a national standard in clinical practice and research in occupational therapy in Canada. The study employed a crossectional design. Participants for the study were former consumers of occupational therapy services, recruited from the Queen's University catchment area (Kingston, North Bay, Oshawa, Perth, Peterborough). A sample of 61 disabled individuals living in the community were recruited. Each individual was sent a package of self-administered measures including the Satisfaction with Performance Scaled Questionnaire, the Reintegration to Normal Living Index, the Life Satisfaction Questionnaire, and the Perceived Problems List. An interview was also arranged with the project coordinator, which was based on the COPM and the Consumer Utility Questionnaire. Multivariate analyses showed that construct validity was supported; scores on the COPM were significantly related to theoretically related constructs: satisfaction with performance, reintegration to normal living and life satisfaction. In addition, criterion validity was supported. A majority of participants (53%), when asked about problems of daily living, spontaneously reported at least one of the problems raised on the COPM. Community utility was evaluated highly by participants, 75% of whom found the COPM useful in identifying and rating their problems, and 100% of whom reported no problems in understanding the COPM.
