Occupational Self-Assessment

The Occupational Self-Assessment (OSA) is a client-centered, reflective tool designed to measure an individual's perception of occupational functioning and identify areas of occupational concern or goals. Developed by Baron, Kielhofner, and colleagues within the Model of Human Occupation (MOHO) framework, the OSA integrates competence self-rating with importance rating, revealing the gap between what the client can do and what matters to them. The OSA is used in occupational therapy across mental health, physical rehabilitation, aging, and developmental disability to identify therapy goals and monitor changes in occupational functioning.
