title: Age differences in psychosocial predictors of positive and negative affect: a longitudinal investigation of young, midlife, and older adults.
abstract: Research has consistently shown that despite aging-related losses, older adults have high levels of emotional well-being relative to those in young and midlife adults. We aimed to contribute to knowledge around the factors that predict emotional well-being over the life course by examining age group differences in associations of positive and negative social exchanges and mastery beliefs with positive and negative affect in a sample of 7,472 young, midlife, and older adults assessed on 2 measurement occasions, 4 years apart. Results from structural equation models indicated lower levels of negative affect with advancing age. Mastery was consistently related to higher well-being, with the strongest associations evident for young adults. Older adults reported the most frequent positive and least frequent negative social exchanges; however, associations of social relations with affect tended to be stronger among young and midlife adults relative to older adults. Results are discussed in the context of life course perspectives on goal orientations and self-regulatory processes.
