Aims: To assess internal consistency, validity and test–retest reliability of Italian version of Canadian Occupational Performance Measure (COPM) in Parkinson’s disease (PD) clients. Methods: Sixty-one subjects completed COPM at baseline, 45 attended re-test within 10 days. Internal consistency and test–retest reliability were determined on average satisfaction and performance scores. Hoehn and Yahr (H&Y) scale and MDS-Unified-Parkinson’s-Disease-Rating-Scale-part III (MDS-UPDRS-III) were used to evaluate disease severity and construct validity. Results: COPM showed moderate-high internal consistency (Cronbach’s alpha 0.684 for performance and 0.805 for satisfaction). Test–retest reliability was moderate for both performance and satisfaction scores (ICC values 0.545–CI95% 0.307–0.720, and 0.693–CI 95% 0.506–0.819, respectively). COPM did not demonstrate significant correlation with H&Y nor MDS-UPDRS-III. Conclusions: COPM is a valid and reliable tool promoting client-centered approach in PD. The role of the client in assessing needs and defining priority outcomes may increase compliance to intervention and awareness of occupational performance.
