Résumé	The Lawton-Brody Instrumental Activities of Daily Living (IADL) Scale, developed by M. Powell Lawton and Elaine M. Brody in 1969, measures the capacity to perform complex, higher-order self-care and household tasks necessary for independent community living. The scale assesses eight domains (for women) or five domains (for men): telephone use, shopping, food preparation, housekeeping, laundry, transportation, medication management, and financial management. It complements basic ADL assessment (measured by the Katz Index) and is essential for comprehensive geriatric evaluation.	The Katz Index of Independence in Activities of Daily Living, developed by Sidney Katz and colleagues in 1963, is one of the earliest and most widely used tools for assessing functional status in older adults and persons with chronic illness. The scale evaluates six essential self-care activities (bathing, dressing, toileting, transfer, continence, feeding) through direct observation or interview and assigns an overall grade (A through G) reflecting the degree of independence. It remains a foundational instrument in geriatric assessment, rehabilitation medicine, and long-term care settings.
