Background and Aim: Mothers of children with cerebral palsy (CP) experience limitation in occupational performance because of caring of their children. It is proposed that the standard measurements need to be assessed their occupational performance problem. The aim of this study was to translate "Canadian Occupational Performance Measure (COPM) into Persian and to test its content validity and reliability in Iranian mothers of children with cerebral palsy.

Materials and Methods: It was a non experimental methodology study. After permission from innovators, COPM was translated into Persian language in three phases with respect to IQOLA project. Each of the items was validated by a panel of ten experts to review each item on “appropriate” and “not appropriate”. For examining test-retest reliability Iranians version of COPM was responded twice within at least two days or at most one week interval, by 30 Iranian mother of a child with CP in the rehabilitation clinic under the supervision of University of Social Welfare & Rehabilitation Sciences (USWR). We used to sample of convenience and non probability design for sampling. Then, data were analyzed with SPSS software from the aspects of content validity and test-retest reliability.

Results: Content validity rate of the Persian version demonstrated a high content validity (80.95±0.222). The Spearman correlation coefficients of the test and retest scores ranged from r=0.84 for performance to r=0.87 for satisfaction and this indicated a high correlation between scores and acceptable reliability of the Persian version of COPM.

Conclusion: It was concluded that the Persian version of COPM can be applied reliability to mothers of children with CP and it can be used for clinical as well as research purposes.
