Резюме	The WHOQOL-BREF is the brief version of the World Health Organization's quality of life assessment, developed by the WHO Quality of Life Group and published in 1998. It measures quality of life across physical, psychological, social, and environmental domains in a single 26-item self-report questionnaire. It has become the primary quality of life instrument in global health research and clinical practice.	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 SF-12 is a brief, 12-item version of the SF-36 health survey developed by Ware, Kosinski, and Keller in 1996. Designed to reduce respondent burden while maintaining psychometric validity, it has become the standard instrument for large-scale surveys, epidemiological studies, and health outcomes research where administration time is critical.
