Looking back and looking ahead: Adult age differences in consistency of diachronous ratings of subjective well-being.

The goal of this study is to investigate the consistency of diachronous ratings of subjective well-being (SWB). A heterogeneous sample (25-74-year-olds; N=3,596) provided ratings of their present SWB, reconstructed their SWB of 10 years ago, and anticipated their SWB 10 years from now. Developmental tasks and self-evaluative principles were used to predict age differences in diachronous consistency. As predicted, in young adulthood, past SWB was rated lower and future SWB higher than present SWB. In contrast, in later adulthood, the past was rated higher and the future lower than present SWB. Analyses of rank-order consistency demonstrated that in later adulthood both future and past SWB were more strongly related to present SWB than in young adulthood. Results show how models of self-evaluation play out at different points in the life span. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
