Positive emotion is associated with 6-year change in functional status in individuals aged 60 and older

Abstract

Analyses examined both positive emotion (PE) at baseline and change in PE from baseline to follow up as predictors of change in functional status (FS). Initial models examined baseline PE, and change in PE, as predictors of change in FS adjusted for baseline PE, negative emotion (NE), FS, and age and gender. Final models included additional adjustments for frequency of social contact, marital status, body mass index, smoking status, drinking behavior, and comorbidity at baseline. Baseline PE was a predictor of change in FS, adjusted for NE, age, and gender (p = 0.033). Additional covariates reduced the effect of baseline PE as a predictor of change in FS (p = 0.115). Change in PE was a significant predictor of change in FS – increases in ratings of PE over time were associated with less decline in FS (p = 0.001). The association for change in PE remained significant in the fully adjusted model (p = 0.004). Results replicate our prior findings.
