The Functional Status Index scores across how many domains?

• A. Seven domains
• B. Three domains
• C. Five domains
• D. One domain

Answer: (B)

The Functional Status Index is a multi-domain measure of a person’s functional abilities. It assesses function in three areas: activities of daily living (self-care tasks), mobility (movement and transfers), and social participation (the ability to engage in usual roles and life activities). This three-domain structure allows the instrument to capture a broad picture of how well someone can function in daily life, not just a single aspect. Choosing three domains reflects its design to span essential aspects of independence, movement, and participation, whereas more domains would overextend the measure and a single domain would miss important facets of function.
