As the world's population continues to age, the ability to assess and understand the functional status of older adults and individuals with disabilities has become increasingly important. The Katz Index of Independence in Activities of Daily Living, often referred to as the Katz ADL Index, is a fundamental assessment tool used in healthcare to evaluate a person's capacity to perform essential activities of daily living. Developed by Sidney Katz in 1963, this index has played a pivotal role in the care and support of individuals with various health conditions.
Assessing independence:
The Katz Index is a straightforward and widely accepted measurement that focuses on an individual's ability to carry out six basic activities of daily living:
- Bathing: Can the person wash themselves independently, or do they require assistance?
- Dressing: Can they put on and take off clothes without help?
- Toileting: Is the individual capable of using the toilet on their own?
- Transferring: Can they move from one place to another, such as from a bed to a chair, without assistance?
- Continence: Can they control their bladder and bowel functions without help?
- Feeding: Can the person eat without requiring assistance?
Each activity is evaluated as either "independent" or "dependent." The Katz Index simplifies the assessment process, making it accessible to a wide range of healthcare professionals.
Clinical significance:

The Katz Index serves as a vital tool for healthcare providers, caregivers, and family members. By assessing a person's ability to perform these basic activities, clinicians can gain insight into their overall functional status. This information is crucial in determining appropriate care plans, predicting future needs, and assessing the impact of medical interventions or therapeutic measures.
In long-term care settings, the Katz Index can help identify individuals who may require additional support, whether it be assistance with activities of daily living, adaptive equipment, or modifications to their living environment. It also aids in gauging the progression of degenerative conditions, such as Alzheimer's disease or mobility impairments.
Moreover, the Katz Index assists in measuring the success of rehabilitation programs and tracking improvements or declines in a patient's functional status over time.
Overview of Katz Index Activities
| Activity | Assessed in Katz Index | Scoring | Examples of Independence |
|---|---|---|---|
| Bathing | Yes | Independent (1) / Dependent (0) | Can bathe without assistance. |
| Dressing | Yes | Independent (1) / Dependent (0) | Can dress fully without help. |
| Toileting | Yes | Independent (1) / Dependent (0) | Uses the toilet independently. |
| Transferring | Yes | Independent (1) / Dependent (0) | Moves in/out of bed unaided. |
| Continence | Yes | Independent (1) / Dependent (0) | Full control over bowels/bladder. |
| Feeding | Yes | Independent (1) / Dependent (0) | Can eat without assistance. |
The Katz Index of Independence in Activities of Daily Living is a valuable tool that has stood the test of time in healthcare. Its simplicity and focus on essential daily activities make it a cornerstone for assessing a person's functional independence, particularly among older adults and individuals with disabilities. By using this index, healthcare professionals can make informed decisions about care and support, enhancing the quality of life for those they serve.

2. Who can use the Katz Index?
The Katz Index can be used by healthcare professionals, caregivers, or family members to evaluate the level of independence of elderly individuals or patients with physical or cognitive impairments.
3. How is the Katz Index scored?
Each activity is scored as either independent (1) or dependent (0). The total score ranges from 0 (completely dependent) to 6 (fully independent).
4. What does a high score on the Katz Index mean?
A high score, such as 6, indicates that the individual is fully independent and can perform all assessed activities without assistance.
5. What does a low score on the Katz Index mean?
A low score, such as 0 or 1, suggests that the individual is highly dependent and requires assistance for most or all activities.
