Background:
Due to its complex nature, cerebral palsy (CP) leads to impairments in body structure and functions, decreased participation and affected occupational performance. The Canadian Occupational Performance Measure (COPM) is commonly used with both children diagnosed with CP and their parents, but it has not been culturally adapted in this population. The primary aim of this study was to evaluate the psychometric properties (validity and reliability) of the COPM when used directly with children with CP. A secondary aim involved translating the specific administration instructions into Turkish to facilitate child self-report.
Methods:
All analyses conducted to examine validity and reliability were performed using the COSMIN (Consensus-based Standards for the selection of health status Measurement Instruments) guideline. The scale and instructions were translated following Beaton's procedure.
Results:
The discriminative construct validity analysis revealed no significant gender-based differences in COPM performance and satisfaction scores (p = 0.75, p = 0.11), indicating consistency across genders. Item analysis showed acceptable internal consistency (Cronbach's alpha: 0.76-0.81). Test-retest analysis demonstrated excellent reliability for time-related equability in COPM performance and satisfaction parameters (ICC > 0.9).
Conclusion:
The COPM is a valid and reliable measurement tool for children aged 8-18 with CP, with adapted instruction in Turkish.
