Which statement best distinguishes IADLs from ADLs?

• A. IADLs require more complex interactions and are performed in home/community contexts beyond basic self-care.
• B. IADLs are purely social activities with no physical component.
• C. IADLs are always completed independently without support.
• D. IADLs are the same as ADLs, just labeled differently.

Answer: (A)

Distinguishing IADLs from ADLs centers on complexity and context. ADLs are basic self-care tasks essential for daily functioning, like feeding, dressing, bathing, toileting, and mobility. IADLs go beyond these basics and require planning, organization, and interaction with the environment; they enable independent living and are typically performed in home or community settings. This is why the statement that best distinguishes them notes that IADLs require more complex interactions and occur in home or community contexts beyond basic self-care. IADLs are not purely social activities, they often involve physical and cognitive components, and they are not always performed independently, nor are they identical to ADLs—ADLs are foundational self-care tasks, while IADLs add the complexity needed for independent life.
