Optimism and social support moderate the indirect relationship between self-efficacy and happiness through mental health in the elderly.

We examined the role of self-efficacy, social support, optimism, and mental health in the prediction of happiness in the elderly. Moderated mediation analyses confirmed a full mediation in which self-efficacy, through perceived mental health and moderated by social support, predicts happiness moderated, in turn, by optimism. When an elder is self-efficacious, his or her mental well-being seems more likely to be improved and translated into enhanced happiness when social support and optimism are moderate to high. We provide preliminary results on the interplay of these psychosocial resources in improving subjective well-being that may help in designing tailored interventions for promoting happiness in late adulthood.
