Longitudinal examination of the functional status of older adults: Successful aging within a representative Canadian sample

Palmore, Nowlin, and Wang (1985) posit a theoretical framework in which to predict the health status of older adults over time as a function of social, economic, physical and mental health variables. The current study provides the first independent, empirical test of this model based upon longitudinal data derived from a representative sample of older British Columbians. The results of this study support the basic structure of the Palmore model; however, various revisions were required to improve the fit of data. Findings indicate that demographic and socio-economic variables have a direct effect upon functional status at baseline. Results further suggest significant consistency in the functional status of older adults over a two-year interval. Directions for future research as well as limitations of the current study are discussed.
