Validation study evaluates a single-item health measure in elderly individuals, indicating nuanced limitations despite satisfactory psychometric properties.
Researchers concluded that Item 2 of the Short-form General Health Survey of the Medical Outcomes Study can be used as a single-item measure of health-related quality of life. This conclusion is tested again on a random sample of elderly people in the Netherlands. Although it can be concluded that the psychometric properties of the short form are satisfactory, the use of the single item as a measure of health-related quality of life is discussed.
