A multidimensional model of the quality of life in older age.

The broad aim of the research presented here was to define the constituents and indicators of quality of life (QoL) in older age, in order to offer a more multidimensional and useful model of quality of life, based on the perspectives of older people themselves. This paper focuses on the extent to which self-evaluations of global QoL are influenced by health, psychological and social variables, and social circumstances. It reports the results of a national survey of the quality of life in people aged 65 and over, living at home in Britain. Multiple regression analysis with the self-evaluation of quality of life rating as the dependent variable showed that the overall model (Model 9) of QoL indicators explained 26.7% of the variance in quality of life ratings. This is sizeable given the amorphous nature of this concept. The main independent predictors of self-rated global quality of life were: social comparisons and expectations, personality and psychological characteristics (optimism-pessimism), health and functional status and personal and neighbourhood social capital. These variables explained the highest proportion of the variance between groups in their quality of life ratings. Socio-economic indicators contributed relatively little to the model.
