Muhtasari	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.	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.
