Subjective well-being in later life: Issues concerning measurement and prediction

This paper reviews the research on the measurement and prediction of subjective well-being in later life. Psychometric data on several gerontological scales are presented in detail. Structural analyses of a variety of measures of subjective well-being are discussed and evidence for a one factor structural solution to subjective well-being is presented. Objective predictors of subjective well-being are discussed with respect to the strength of their relationships to subjective well-being. It is concluded that subjective well-being is the best predictor of itself. Evidence of temporal stability and corss-situational consistency, combined with the evidence of a one factor structural solution, suggests that subjective well-being has trait-like characteristics. Suggestions for future research are presented.
