Relations between health-related quality of life and well-being: the gerontologist's new clothes?
Is the recent construct of health-related quality of life (HQL) distinct from what gerontologists have long referred to as "well-being" or "life satisfaction?" We addressed this question using data from men in the VA Normative Aging Study to examine relations among twelve scales assessing HQL and seven scales of well-being (WB). We hypothesized that these two constructs would be distinct factorially, and that the derived factors would have different correlates. Correlations between scales of HQL and WB were moderate. When the nineteen scales were factored, four factors were extracted with HQL and WB scales generally loading on separate factors. The factors had distinct patterns of relations with general quality of life, personality, and the presence of a health problem, controlling for sociodemographics. These results suggest that HQL is distinct from the older construct of well-being. Although the two constructs are conceptually related, there is only a moderate amount of statistical overlap between them. Gerontologists should readily adopt health-related quality of life, which maintains continuity with such classics as well-being. This new construct, although needing slight alterations to broaden its assessment of well-being and life satisfaction, holds promise as more than an accessory in the study of health and well-being among older persons.
