A concise alternative for researching health‐related quality of life in older people

Abstract

Researchers have a wide range of tools for health assessments to choose from, some of which can be lengthy and time consuming. The purpose of this paper is to examine a potentially shorter alternative, the EQ‐5D instrument, with a community dwelling population sample of older people. Data was obtained using trained interviewers from a randomly sampled crosssectional survey of community dwelling older people. 423 people aged 70‐99 were interviewed. Information was obtained relating to activities of daily living, the EQ‐5D, the EQ‐VAS, the SF‐36, use of health and social care services and the presence or absence of a limiting illness, disability or infirmity. In terms of construct validity, the EQ‐5D was able to distinguish between hypoThesised differences in the sample that could be expected to reflect differences in health‐related quality of life. The EQ‐5D items correlated well with conceptually similar items. Completion rates for the EQ‐5D items were good, ranging from 98.3‐98.8%. Completion rates for the EQ‐VAS were 98.1%. The results suggest that the EQ‐ 5D may provide a valid measure of health‐related quality of life in a cross‐sectional population sample of older adults, although the emphasis of the scale is very much on physical health and functioning. The results for the depression/anxiety item suggest that additional information may be needed if mental health is of concern.
