The Zarit Burden Interview (ZBI) is a commonly used assessment tool designed to quantify the psychological and emotional burden experienced by caregivers who provide care for individuals with cognitive or functional impairments. Developed by Zarit and colleagues, the scale consists of 22 items that cover various aspects of caregiver burden, such as time pressure, emotional strain, and social isolation. The scoring ranges from 0 to 88, with higher scores indicating a greater level of caregiving burden. This tool aids healthcare professionals in identifying the psychological stress faced by caregivers and provides appropriate support and interventions to improve their mental health and quality of life.

The SF-36 (Short Form 36 Health Survey) is a widely used generic health status assessment tool developed by the Medical Outcomes Study (MOS) Group. The scale is designed to comprehensively evaluate health-related quality of life, encompassing eight dimensions: physical functioning, social functioning, role limitations due to physical health, role limitations due to emotional problems, bodily pain, mental health, vitality, and general health perceptions. Each dimension consists of several items, and scores are derived by summing the scores of these items, typically converted to a 0 to 100 percent scale, with 100 representing the best possible health state. These eight dimension scores can be combined to form two summary scores: the Physical Component Summary (PCS) and the Mental Component Summary (MCS).

The Harris Hip Score is a clinician-reported outcome measure assessing hip function, including pain, function, absence of deformity, and range of motion, used to evaluate outcomes after hip surgery.
