It has not been well understood how conscientiousness and neuroticism are associated with two related but distinct dimensions of perceived control (i.e., perceived mastery and constraints) among aging adults. The present study examined these associations and their change over time, while addressing whether they differ by age or gender. For respondents aged 50+ at baseline (N = 2,768) in the Midlife in the United States (MIDUS) study, multilevel modeling analyses were conducted to assess how conscientiousness and neuroticism predicted perceived mastery and constraints over 2 decades. As expected, higher conscientiousness and lower neuroticism (for both between- and within-person variability) predicted higher perceived mastery and lower perceived constraints overall. Nuanced findings emerged related to age, gender and change over time for different associations of conscientiousness and neuroticism with the outcomes. These findings can inform future research suggesting directions of further investigations for these complex associations.
Background and Objectives
Research suggests longitudinal and reciprocal relationships between perceived control over life circumstances and health for Western populations; yet, such associations have not been fully understood for non-Western populations. The present study addresses cultural differences in these associations for American and Japanese aging adults.
Research Design and Methods
For respondents aged 40+ at two waves (Time 1 [T1] and Time 2 [T2]) of Midlife in the United States (N=4,455) and Midlife in Japan (N=827), cross-lagged path models were analyzed for: T1 perceived control predicting change in each health measure (i.e., self-rated health, number of chronic health conditions, functional limitations) from T1 to T2; and, the matched T1 health measure predicting change in perceived control from T1 and T2. In these analyses, the effects of T1 age, T1 perceived control, and each T1 health measure were compared cross-nationally.
Results
A cross-national difference emerged in that T1 perceived control predicted change in chronic health conditions only for Americans. Similar tendencies were found between the two nationalities for T1 perceived control predicting changes in self-rated health and functional limitations. Reciprocal relationships between perceived control and health measures were found for Americans, but neither age nor any of T1 health measures predicted change in perceived control for the Japanese respondents.
Discussion and Implications
The findings suggest cultural differences and similarities between the two nationalities, which have implications for potential health benefits of enhancing perceived control among American and Japanese aging adults. Building on these findings, the present study also indicates future directions of research.
