The framework used to guide evaluation in an interdisciplinary team for adult mental health, focusing on fit between person, environment, and occupation, is known as:

• A. MOHO
• B. PEO interaction
• C. Ecology of Human Performance
• D. Kawa model

Answer: (B)

The key idea here is that occupational performance comes from how well a person, their environment, and the tasks they want or need to do fit together. The Person-Environment-Occupation model treats performance as the result of this ongoing alignment among three elements. When the person’s abilities, preferences, and needs align with supportive environments and meaningful occupations, participation and function improve.

In an interdisciplinary mental health team, this framework guides evaluation by keeping the discussion focused on how each domain influences real-life participation. You assess person factors (skills, cognition, energy, motivation), environmental factors (home setup, safety, social supports, access to services, policies), and the occupations themselves (the tasks, routines, and roles that are meaningful). Because the emphasis is on fit, you look for which domain to modify to enhance participation: changing the environment, adapting the activity or task demands, or supporting the person with strategies or skills.

For example, consider someone with a mood disorder who has difficulty maintaining a morning routine. The team would examine how personal factors (sleep, energy, motivation) interact with the environment (alarm systems, housing, family routines) and the occupations (getting dressed, preparing a meal, leaving the house). If the obstacle is environmental or task-related rather than solely due to the person, implementing environmental adjustments or simplifying the morning routine can improve engagement and performance.

Other models focus more on motivation, habitual patterns, or contextual performance in different ways, but the PEO framework specifically centers on the dynamic fit between person, environment, and occupation to guide evaluation and intervention.
