Abstract
Despite experiencing more negative life events, older adults often report better emotional well-being than younger adults, a phenomenon known as the well-being paradox. Although socioemotional selectivity theory suggests that age-related shifts toward present-moment goals may contribute to this pattern, the psychological factors underlying these age differences remain unclear. In particular, mindfulness and personality are both associated with emotional well-being and vary by age, yet their contributions have not been examined simultaneously. In this study, we examined whether dispositional mindfulness and the Big Five personality traits uniquely and statistically accounted for age differences in positive (subjective happiness, positive affect, satisfaction with life) and negative (negative affect, anxiety symptoms, depressive symptoms) emotional well-being. Using survey data from a lifespan sample of 129 adults (40 young, 42 middle-aged, 47 older adults), we conducted parallel mediation analyses. Older age was associated with greater positive emotional well-being and lower negative emotional well-being, which was partially mediated by lower levels of neuroticism. Additionally, greater dispositional mindfulness mediated the inverse association between age and negative—but not positive—emotional well-being. These findings suggest that personality, specifically neuroticism, and dispositional mindfulness may be unique contributors to the well-being paradox.
