Activities of Daily Living (ADLs) are fundamental self-care tasks that represent a person’s physical ability to function independently in everyday life. These basic activities are universally recognized across healthcare, insurance, and social services fields as a standardized method for measuring an individual’s functional status. Successfully performing these tasks is a practical measure of independence. The inability to perform ADLs often signals a need for assistance or supportive care, leading healthcare providers to use ADL assessments to establish a baseline and track changes over time.
The Six Activities of Daily Living
The standard set of six Activities of Daily Living focuses on the most elemental aspects of personal care and hygiene. Independence in these areas is defined by the ability to complete the task without hands-on help or close supervision.
Bathing involves the ability to wash, rinse, and dry one’s entire body, including safely getting into and out of the bath or shower. This activity often requires standing, reaching, and balancing.
Dressing refers to the capacity to select appropriate clothing, put on all items, and manage fasteners such as zippers, buttons, and snaps. This includes the ability to put on or remove braces or artificial limbs.
Toileting is defined by the ability to get on and off the toilet, manage clothing, and perform necessary personal hygiene afterward. Independence in this task focuses specifically on the physical mechanics of using the facility, separate from continence.
Transferring describes the ability to move from one position to another, such as getting in and out of a bed, a chair, or a wheelchair. This activity measures mobility and balance, requiring strength to move the body mass without physical assistance.
Continence is the ability to maintain voluntary control over bladder and bowel functions. This ADL also includes the ability to manage necessary hygiene, such as caring for a catheter or colostomy bag, for individuals unable to maintain full control.
Feeding, also referred to as eating, is the process of getting food from a plate or receptacle into the body. This task specifically assesses the physical capacity to chew, swallow, and use utensils to bring food to the mouth.
Distinguishing ADLs from Instrumental ADLs
While ADLs cover basic self-care, Instrumental Activities of Daily Living (IADLs) involve more complex tasks necessary for living independently within a community. IADLs require higher-level cognitive function and organizational skills, often involving interaction with the environment beyond the immediate self.
Examples of IADLs include managing finances, handling transportation, preparing meals, and managing medications. Difficulty with IADLs often appears earlier than problems with the basic six ADLs, sometimes signaling the initial stages of cognitive decline. For example, a person might be independent in bathing but struggle with complex tasks like balancing a checkbook or navigating public transit.
The distinction is based on complexity, as IADLs build upon the foundation of basic ADLs. The ADL of eating covers the act of feeding oneself, but the IADL of meal preparation encompasses planning, shopping for groceries, and cooking the food. IADLs are often the first tasks for which an individual seeks help, while the need for assistance with basic ADLs indicates a greater loss of functional independence.
Application in Assessing Functional Independence
The standardized assessment of ADLs provides objective data used to determine an individual’s need for care and eligibility for financial benefits. In a formal assessment, a person’s ability to perform each ADL is scored, typically categorized as independent, requiring standby assistance (supervision), or requiring hands-on physical assistance. Standby assistance means a person must be within arm’s reach to prevent injury, such as a fall while transferring.
These scores are important in determining eligibility for long-term care insurance policies. Most policies require an individual to demonstrate a need for assistance with at least two of the six ADLs or have a severe cognitive impairment to trigger benefits. The inability to perform two ADLs without substantial assistance serves as the primary gateway to accessing financial support for home health services or facility care.
The assessment process, often conducted by a nurse or a social worker, uses standardized tools to evaluate functional capacity. This evaluation determines the scope of necessary support, ranging from intermittent home health services to full-time residential care. The ADL assessment connects individuals with the specific level of care and funding required to maintain safety and quality of life.
