ADL vs. IADL: Which is an instrumental activity of daily living: bathing, dressing, denture care, housework?

5 min read

Official assessments show that about 18% of older adults need help with at least one activity of daily living. Understanding these needs starts with a core question: which is an instrumental activity of daily living: bathing, dressing, denture care, housework? This guide clarifies the difference.

Quick Summary

Among the options, housework is the instrumental activity of daily living (IADL). It requires complex cognitive and physical skills beyond the basic self-care tasks classified as activities of daily living (ADLs), such as bathing and dressing.

Key Points

  • The Direct Answer: Housework is the instrumental activity of daily living (IADL) among the options, requiring complex planning, while bathing, dressing, and denture care are basic ADLs.

  • ADLs Defined: Activities of Daily Living (ADLs) are fundamental self-care tasks necessary for survival, such as eating, bathing, and dressing.

  • IADLs Defined: Instrumental Activities of Daily Living (IADLs) are more complex tasks essential for living independently within a community, like managing money, cooking, and housekeeping.

  • Denture Care is an ADL: Oral hygiene, including denture care, is classified under the basic ADL of personal hygiene/bathing, not as a separate IADL.

  • Assessment Determines Care: Evaluating a senior's ability to perform ADLs and IADLs is crucial for determining the appropriate level of support, from weekly help to full-time care.

  • Supporting Independence: Identifying specific challenges allows for targeted solutions, such as meal delivery for IADL struggles or bathroom safety equipment for ADL difficulties.

Understanding the Foundation: What Are Activities of Daily Living (ADLs)?

Activities of Daily Living (ADLs) represent the most fundamental skills required for basic self-care and staying alive. These are the essential tasks an individual must perform every day to care for themselves physically. Healthcare professionals, from doctors to caregivers, use a person's ability to perform ADLs as a primary metric for assessing their functional status, particularly in older adults or individuals with disabilities. When someone begins to struggle with ADLs, it often signals a need for a higher level of personal support.

The six universally recognized basic ADLs include:

  • Bathing and Hygiene: The ability to clean oneself, including getting in and out of a tub or shower, washing hair, and managing oral hygiene like brushing teeth or denture care.
  • Dressing: The ability to select appropriate clothing and to put it on and take it off, including managing fasteners like buttons and zippers.
  • Eating (Feeding): The ability to feed oneself, meaning bringing food from a plate to the mouth. This is distinct from preparing the meal.
  • Toileting: The ability to get to and from the toilet, use it appropriately, and clean oneself afterward.
  • Transferring (Mobility): The ability to move from one position to another, such as getting out of bed and into a chair or moving from a seated to a standing position.
  • Continence: The ability to control bladder and bowel functions completely.

Difficulty with even one of these core activities can significantly impact a person's safety and quality of life, often necessitating interventions like in-home care or a move to an assisted living facility.

Moving Beyond the Basics: What Are Instrumental Activities of Daily Living (IADLs)?

While ADLs are about basic survival, Instrumental Activities of Daily Living (IADLs) are the more complex tasks required to live independently within a community. They involve a higher level of cognitive function, planning, and organization. An individual can often manage all their basic ADLs but still require assistance with IADLs. Assessing IADLs provides a more nuanced view of a person's ability to function safely and effectively on their own.

The primary IADLs include:

  • Housework and Home Maintenance: The ability to maintain a clean and safe living environment. This includes tasks like washing dishes, doing laundry, dusting, vacuuming, and making beds. It requires planning, sequencing, and physical stamina.
  • Meal Preparation: The ability to plan, cook, and serve complete meals. This is more complex than the ADL of eating, as it involves everything from grocery shopping to using kitchen appliances safely.
  • Managing Medications: The ability to take the correct medications at the prescribed times, manage refills, and monitor for side effects.
  • Managing Finances: The ability to handle one's own money, including paying bills on time, managing a budget, and understanding financial transactions.
  • Shopping: The ability to shop for necessities like groceries and clothing, which involves making a list, getting to the store, selecting items, and handling payment.
  • Communication: The ability to use a telephone, manage mail, and use other communication devices to stay connected and handle personal affairs.
  • Transportation: The ability to drive oneself or arrange and use public or private transportation to get to appointments, go shopping, or attend social events.

Struggles with IADLs are often the first sign that an older adult may need additional support to continue living independently at home.

ADLs vs. IADLs: A Head-to-Head Comparison

To clarify the distinction, here is a direct comparison between the two categories:

Feature Activities of Daily Living (ADLs) Instrumental Activities of Daily Living (IADLs)
Core Focus Basic Self-Care & Survival Independent Living in a Community
Complexity Simple, fundamental tasks Complex, multi-step tasks
Primary Skills Physical ability, basic motor skills Cognitive function, planning, organization
Examples Bathing, dressing, eating, toileting Housework, managing money, cooking, shopping
Assessment Purpose Determines need for personal, hands-on care Determines need for supportive services (e.g., housekeeping, meal delivery)

Why Housework Is an IADL and the Others Are ADLs

Based on these definitions, housework is the clear IADL among the choices of bathing, dressing, denture care, and housework.

  • Housework: This is an IADL because it requires planning (what needs cleaning?), sequencing (do I dust before or after vacuuming?), and organization. It's a complex activity necessary for maintaining an independent household, not just for basic personal survival.
  • Bathing & Dressing: These are classic ADLs. They are fundamental self-care tasks focused directly on one's own body.
  • Denture Care: This falls under the ADL category of Bathing and Hygiene. It is a basic personal grooming task, similar to brushing teeth or combing hair.

The Critical Role of Assessment in Senior Care

Understanding the distinction between ADLs and IADLs is not just academic; it's a critical component of effective senior care and planning. Geriatricians and social workers often use standardized tools to evaluate a person's abilities, such as the Katz Index for ADLs and the Lawton-Brody Scale for IADLs. The results of these assessments have profound implications:

  1. Determining the Right Level of Care: A person who only needs help with IADLs (like cleaning and shopping) might thrive with weekly in-home support. In contrast, someone struggling with ADLs (like bathing and transferring) may require daily assistance or the 24/7 support offered by an assisted living community.
  2. Insurance and Benefits Qualification: Government programs like Medicaid and long-term care insurance policies often use ADL and IADL assessments to determine eligibility for benefits. Typically, a person must need help with two or more ADLs to qualify for a higher level of paid care.
  3. Promoting Safety and Independence: By identifying specific areas of difficulty, families and caregivers can introduce targeted solutions. For example, if meal preparation is a challenge (an IADL), a meal delivery service can be a great solution. If bathing is a problem (an ADL), installing grab bars and a shower chair can enhance safety.

Conclusion: A Framework for Dignity and Support

The distinction between Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs) provides an essential framework for supporting healthy aging. ADLs are the non-negotiable tasks of self-care, while IADLs are the pillars of independent living. By correctly identifying housework as an IADL, we recognize it as a complex function that goes beyond basic survival. Understanding this difference allows families, caregivers, and healthcare providers to create tailored, effective, and dignified care plans that empower seniors to live as safely and independently as possible.

Frequently Asked Questions

The seven main IADLs are: managing finances, managing transportation, shopping for necessities, preparing meals, using the telephone or other communication devices, managing medications, and housework/home maintenance.

Cooking, or meal preparation, is a classic example of an IADL. It involves multiple complex steps like planning, shopping, and safely using appliances, which goes beyond the basic ADL of simply eating the food.

Yes, this is very common. An older adult might be perfectly capable of dressing, bathing, and feeding themselves (ADLs) but struggle with the cognitive and organizational demands of paying bills or cooking (IADLs). This is often an early sign that more support is needed.

Healthcare professionals use standardized tools. The most common are the Katz Index of Independence in Activities of Daily Living (for ADLs) and the Lawton-Brody Instrumental Activities of Daily Living Scale (for IADLs).

Managing money is an IADL because it requires high-level executive function, including abstract thinking, planning, and memory. It involves paying bills on time, creating a budget, and avoiding scams, all complex tasks required for independent living.

Generally, original Medicare does not pay for long-term custodial care (help with ADLs and IADLs). It may cover short-term care from a home health aide if you are also receiving skilled nursing care. Long-term care insurance or Medicaid are more common sources of funding for this type of assistance.

Walking is a component of the ADL known as 'transferring' or 'mobility.' This ADL assesses a person's ability to move their body from one place to another, such as getting out of a chair or walking across a room.
