Muhtasari	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 Zarit Caregiver Burden Interview, developed by Steven H. Zarit and colleagues in 1980, is a widely used assessment tool designed to quantify the subjective burden experienced by informal caregivers of persons with dementia or other chronic illnesses. The 22-item instrument measures emotional, financial, and physical strain related to caregiving and has become a standard in geriatric, gerontology, neurology, and behavioral health settings worldwide.
