Ringkasan	The EQ-5D is a standardized, preference-based health utility measure developed by the EuroQol Group in 1990. It combines a descriptive health profile (five dimensions, three or five response levels) with a visual analog scale to quantify overall health status. The instrument has become essential for health economics, clinical trials, and cost-effectiveness analysis worldwide.	The Health Assessment Questionnaire Disability Index (HAQ-DI) is a 20-item self-report measure of functional disability developed by Fries and colleagues at Stanford University in 1980. Originally designed for rheumatoid arthritis, the HAQ-DI has become the gold-standard functional assessment instrument across diverse rheumatic diseases and chronic conditions.	The SF-36 is a generic, self-administered 36-item questionnaire measuring eight dimensions of health status. Developed by Ware and Sherbourne in 1992, it has become the most widely used health survey in clinical trials, outcomes research, and population health monitoring. It assesses perceived health across physical and mental domains relevant to the general adult population.
