OT 6220 – Assessment and Measurement in Occupational Therapy Practice Test

The Katz Index of Independence in Activities of Daily Living is commonly used for assessing activities of daily living (ADL) because it specifically focuses on the performance of daily tasks essential for independent living. The index evaluates six basic ADLs: bathing, dressing, toileting, transferring, continence, and feeding. Each activity is scored as either independent or dependent, providing a clear framework to determine an individual’s level of function and need for assistance.

This scale's simplicity and effectiveness in categorizing levels of independence make it a preferred tool in both clinical and research settings. It allows practitioners to identify individuals who may need support or intervention in achieving independence in their daily lives, facilitating tailored care plans. Furthermore, the Katz Index has been widely validated and used across varied populations, enhancing its credibility as a reliable assessment tool for ADLs.
