The capacity to perform daily tasks is a cornerstone of independence, particularly as we age. In healthcare, these tasks are divided into two categories: Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs). While ADLs cover fundamental self-care needs, IADLs require more complex organizational, cognitive, and physical skills. Recognizing a decline in IADL proficiency can be a vital first step in seeking appropriate support and care.
The Difference Between ADLs and IADLs
Understanding the distinction between these two sets of activities is crucial for assessing an individual's functional abilities. ADLs are the basic, personal self-care tasks, while IADLs are more advanced tasks that support independent community living. IADL performance often builds upon a foundation of successfully completing ADLs.
Activities of Daily Living (ADLs)
ADLs are fundamental self-care tasks essential for personal well-being. These include:
- Bathing and Hygiene
- Dressing
- Eating/Feeding
- Toileting
- Continence
- Transferring
Instrumental Activities of Daily Living (IADLs)
IADLs are more complex activities that enable independent living within a community. Examples include:
- Meal Preparation
- Managing Finances
- Housekeeping
- Shopping
- Medication Management
- Transportation
- Communication
IADL vs. ADL Comparison Table
| Feature | Instrumental Activities of Daily Living (IADLs) | Activities of Daily Living (ADLs) |
|---|---|---|
| Complexity | More complex; requires higher cognitive function and planning. | Basic and fundamental; involves simple, everyday self-care. |
| Examples | Meal preparation, medication management, managing finances, shopping. | Bathing, dressing, eating, toileting, ambulating. |
| Skills Required | Involves executive function, organization, and problem-solving. | Primarily physical skills and basic motor coordination. |
| Focus | Functioning independently in the community. | Personal self-maintenance and well-being. |
| Assessment Indicators | Often the first to decline as an individual ages or experiences cognitive issues. | Typically impacted later in disease progression or with significant physical impairment. |
The Role of IADLs in Senior Care and Assessment
Assessing IADL abilities is a standard part of evaluating an older adult's functional status and determining the level of support required. Declining IADL function can indicate early health issues or cognitive changes. Tools like the Lawton-Brody IADL scale help professionals measure these abilities and inform care planning, including decisions about home care or assisted living.
Supporting Declining IADL Ability
When IADL performance decreases, various interventions can help maintain independence. These include home modifications, in-home care services, assistive technologies, assisted living communities, and rehabilitation services like occupational therapy.

Conclusion
Identifying which of the following is IADL is vital for understanding the needs of aging individuals. IADLs represent the complex tasks necessary for independent community living, distinct from basic ADLs. Recognizing and addressing IADL decline early allows for proactive support, improving quality of life and promoting continued independence.
