Positive psychology constructs as predictors of depression in retirees

This study investigated whether five positive psychological constructs (self-efficacy, gratitude, grit, hope and optimism) had a combined effect on levels of depression. The co-occurrence of these psychological factors, defined as an example of covitality, was examined in relation to predicting lower levels of depression. Participants were 278 retirees living in Brisbane, Australia. Each participant completed either an online or hard-copy self-report, related to positive psychological functioning. A standard multiple regression found that self-efficacy, grit, optimism and hope were individually all significant predictors of depression (small effect sizes); however, the combinatorial relation of all these four factors with depression was substantial (R-2 = 0.34; large effect size). Gratitude was not a significant predictor. While no causality can be inferred from this cross-sectional study, having a combination of positive psychological factors might have an effect on levels of depression in retirement.
