The Occupational Therapy Practice Framework (OTPF) is the core competency of occupational therapy in the United States. The OTPF framework is divided into two sections: domain and process. The domain includes environment, client factors, such as the individual's motivation, health status, and status of performing occupational tasks. The domain looks at the contextual picture to help the occupational therapist understand how to diagnose and treat the patient. The process is the actions taken by the therapist to implement a plan and strategy to treat the patient.
