The World Federation of Occupational Therapists defines occupational therapy as a profession concerned with promoting health and well-being through occupation. The primary goal of occupational therapy is to enable people to participate in the activities of everyday life. Occupational therapists achieve this outcome by enhancing the individual's ability to participate, by modifying the environment, or by adapting the activity to better support participation.
Another way of thinking about the ideas contained in these definitions could be: occupational therapy is about understanding the importance of an activity to an individual, being able to analyze the physical, mental and social components of the activity and then adapting the activity, the environment and/or the person to enable them to resume the activity. Occupational therapists would ask, "Why does this person have difficulties managing his or her daily activities (or occupations), and what can we adapt to make it possible for him or her to manage better and how will this then impact his or her health and well-being?”
