Optimism and well-being in older adults: the mediating role of social support and perceived control.

To investigate how psychosocial resources may improve well-being for older adults, this study explored the relationship among questionnaire measures of optimism, social support and perceptions of control in predicting subjective well-being (measured with the positive affect subscale of the Affect Balance Scale) (Bradburn, 1969) and psychological well-being (measured with the purpose in life scale of the Ryff Psychological Well-being scales) (Ryff, Lee, Essex, & Schmutte, 1994) among older adults. The potential mediating roles of perceived social support and perception of control were also explored. Participants were 225 adults aged from 65 to 94 years. Optimism was found to be a predictor of both subjective and psychological well-being, and perceived social support was found to mediate the relationship between optimism and subjective well-being, but not psychological well-being. In contrast, perception of control was found to mediate the relationship between optimism and psychological well-being, but not subjective wellbeing. Longitudinal research is needed to confirm these pathways.
