In an early psychosis program team, which framework is used to evaluate the interaction among person, environment, and occupation?

• A. Biomechanical model
• B. Person-environment-occupation interaction
• C. Cognitive-behavioral framework
• D. Model of Human Occupation

Answer: (B)

Understanding how a person, their environment, and the tasks they perform interact to shape daily functioning is the central idea. The Person-Environment-Occupation (PEO) model is built around that exact fit: performance emerges from how well the person’s abilities, needs, and goals align with the environmental context and the occupations they undertake. In an early psychosis program, using this framework means assessing each element—what the person can do and wants to do, what the surrounding setting supports or hinders, and which meaningful activities or roles are most important—and then shaping interventions to optimize the fit. This may involve modifying the environment (adding supports, reducing barriers), choosing or breaking down meaningful occupations, or supporting the person’s skills and preferences to improve engagement and performance.

The other frameworks focus on different aspects of performance. A biomechanical model centers on physical factors like joints, strength, and movement. A cognitive-behavioral framework targets thoughts, beliefs, and behaviors to change symptoms and coping strategies. The Model of Human Occupation emphasizes motivation, habitual patterns, and performance capacity but does not explicitly foreground the triadic interaction among person, environment, and occupation in the same explicit way as the PEO model.
