Single-item vs multiple-item measures of health-related quality of life.
Many survey instruments measure health-related quality of life. Researchers can choose from instruments ranging in length from one to several hundred items. A small sample of 35 chronically ill adults self-administered the Short-form General Health Survey of the Medical Outcomes Study, a 20-item health-related quality-of-life measure with established reliability and validity. One specific item on the MOS questionnaire can serve as a single-item measure of health-related quality of life. This one item correlated positively and significantly with the over-all score for health-related quality of life. The results of this analysis support the use of this single-item measure of health-related quality of life when multiple-item instruments are not suitable due to limitations of resources or sample size.
