Occupational Repertoire Development Measure – Parent (ORDM-P): Face validity, comprehensiveness, and internal consistency

Introduction: An occupational repertoire is the array of occupations that an individual has the perceived capacity to perform at a specific point in time. The Occupational Repertoire Development Measure – Parent is a new tool that uses parent report to identify the occupations children can and do perform and their interests in and opportunities for doing them. This study aimed to test the face validity, comprehensiveness, and internal consistency of the Occupational Repertoire Development Measure – Parent as a tool to measure the occupational repertoire of children aged between 2 and 12 years. Method: Twenty-nine occupational therapists completed an online questionnaire about the Occupational Repertoire Development Measure – Parent, and 27 parents completed it and then provided feedback via a structured interview. Descriptive statistics, content analysis, and the content validity index guided data analysis. Results: Participants view the Occupational Repertoire Development Measure – Parent as practical, simple, and supportive of occupation-centred practice to optimize children’s development of a meaningful repertoire. Overall, self-care occupations were rated highly relevant. Lower-scoring occupations were those perceived as performed only by older children, nonessential for children with disabilities, or culturally unimportant. Conclusion: Results indicate value in the further development of the Occupational Repertoire Development Measure – Parent and validate that it asks relevant questions to understand a child’s performance, engagement, and opportunities, leading to optimal repertoire development.
