This paper outlines the process of incorporating the "Guidelines For the Client-Centred Practice of Occupational Therapy" into the practice of occupational therapy in an out-patient rehabilitation facility serving young people with physical disabilities. Specifically, the areas of practice addressed are screening and assessment. The process started in 1987 with an identification of the need to find a holistic framework that meets the complex needs of clients with chronic physical disabilities. The conceptual model of occupational performance, as outlined in the Guidelines, provided such a framework. The process of incorporating the Guidelines into the screening and assessment practices of occupational therapists at Erinoak Serving Young People With Physical Disabilities is described, with examples of documents developed by the department. Suggestions are given to integrate the conceptual model of occupational performance into the practice of occupational therapists working with children and adolescents with physical disabilities.
