As the profession of occupational therapy continues to mature and expand its practice, the measurement of occupational performance is one of the key avenues that all practicing clinicians will need to explore and master. Measuring Occupational Performance: Supporting Best Practice in Occupational Therapy, Third Edition summarizes the measurement tools needed to assess client occupational performance, to provide the best intervention, and to document the effectiveness of that intervention. These measurement tools are not just a compilation of all that are available for measurement relevant to occupational therapy; they are an elite group of tools carefully selected by the editors through a process of rigorous theoretical, clinical, and scientific reasoning.
