QoL is typically measured using validated questionnaires and scales. Some commonly used instruments include the SF-36 (Short Form Health Survey), the WHOQOL (World Health Organization Quality of Life), and the EQ-5D (EuroQoL-5 Dimensions). These tools assess various domains such as physical functioning, emotional well-being, social relationships, and environmental factors. The choice of instrument often depends on the specific population and context being studied.
