Health-Related Quality of Life
Health-related quality of life (HRQOL) is a broad multidimensional concept that usually includes subjective evaluations of both positive and negative aspects of health. It includes perceptions of physical and mental health, including health risks and conditions, functional status, and social support. Measuring HRQOL can help determine the burden of preventable disease, injuries, and disabilities, and it can provide valuable new insights into the relationships between HRQOL and risk factors. HRQOL questions have become an important component of health surveillance and are generally considered valid indicators of service needs and intervention outcomes. Self-assessed health status may even be a more powerful predictor of mortality and morbidity than many objective measures of health. Tracking HRQOL measures make it possible to demonstrate scientifically the impact of health on quality of life.
