The OTPF Domain: How Occupational Performance Is Organized
Knowing these influences well is also the foundation for almost every intervention question in Domain 2, because you cannot choose a safe, well-graded activity without knowing what the condition does to the body, the mind and daily life.
The exam rarely asks you to recite a definition of a diagnosis. Instead, it describes a client and expects you to recognize what the condition means for function and safety: the precaution that applies, the symptom that should be reported to the supervising OTR, or the occupation most likely to be affected. Read this section as a clinician would. For each condition, ask three questions: What is happening in the body? What does it do to daily occupations? What must the occupational therapy assistant watch for and report?
This chapter reviews the domain portion of the Occupational Therapy Practice Framework (OTPF), the shared vocabulary the exam uses to describe clients. Every condition in later chapters affects one or more parts of this domain, so knowing the categories helps you sort the details in a question stem quickly.
The Five Aspects of the Domain
The OTPF describes the domain of occupational therapy as five interrelated aspects. None of them is more important than the others; the client's engagement in occupation is the central goal.
| Category | Examples |
|---|---|
| ADLs | Bathing, toileting, dressing, eating and swallowing, feeding, functional mobility, grooming, sexual activity |
| IADLs | Meal preparation, shopping, financial management, home management, driving and community mobility, care of others and pets |
| Health management | Medication routines, symptom management, nutrition, physical activity |
| Rest and sleep | Rest, sleep preparation, sleep participation |
| Education, work, play, leisure, social participation | Classroom tasks, job tasks, play exploration, hobbies, family and community involvement |
Performance Skills Versus Client Factors
A frequent source of confusion is the difference between a performance skill and a client factor. A client factor is an underlying capacity, such as grip strength, range of motion, memory or visual acuity. A performance skill is the observable action during a real task, such as reaching for a cup, sequencing the steps of making toast, or taking turns in conversation. A client can have adequate shoulder range (client factor) but still reach poorly during dressing because of fear of falling or poor planning (performance skill).
Performance Patterns and Contexts
Performance patterns are often disrupted by illness. A retired teacher who walked to the bakery every morning loses a habit, a routine and a social connection after a hip fracture. A child with autism may depend heavily on a predictable routine and become distressed when it changes. Roles such as parent, worker, student, caregiver and volunteer give life meaning, and losing a role can trigger depression.
Contexts can be supports or barriers. Stairs at the front door, a supportive spouse, a school policy that allows extra time, limited bus routes, a culture that values family caregiving, and an insurance plan with few covered visits are all contexts. The exam expects the COTA to notice them and report them, because the OTR uses them in planning and the COTA uses them in carrying out intervention.
The Process Side of the Framework
The OTPF process is evaluation, intervention and outcomes. The OTR is responsible for evaluation and the intervention plan; the COTA contributes data, implements the plan, monitors response and reports to the OTR. Intervention approaches are create or promote (health promotion for everyone), establish or restore (remediation), maintain, modify (compensation or adaptation) and prevent. You will see these approaches throughout the guide.
Key Takeaways
- The OTPF domain has five aspects: occupations, contexts, performance patterns, performance skills and client factors.
- Feeding (getting food to the mouth) is different from eating and swallowing (handling food in the mouth and swallowing).
- Client factors are underlying capacities; performance skills are observed actions during a task.
- Habits, routines, roles and rituals are often disrupted by illness and are legitimate intervention targets.
- Environmental and personal contexts can be barriers or supports; the COTA notices and reports them to the OTR.
