Meta-analytic evidence has shown that personality is one of the strongest correlates of global and domain-specific satisfaction. The main goal of the present study was to examine whether the associations between personality traits and satisfaction differ across the adult lifespan. We used bivariate latent growth curve models and local structural equation modeling to study correlations between levels and change of Big Five personality traits and satisfaction with life, satisfaction with work, and satisfaction with social contacts. Data came from a large representative longitudinal Dutch sample (N = 9,110; age range 16-95). Across age, emotional stability showed the strongest associations with both global and domain-specific satisfaction. After emotional stability, conscientiousness was the strongest correlate of work satisfaction (WS), and extraversion and agreeableness were the strongest correlates of social satisfaction (SS). Longitudinal changes in personality and satisfaction across the 11 years covered in this study were moderately correlated, suggesting codevelopment between these constructs. Most correlational patterns were stable across the lifespan, indicating that personality traits are similarly relevant for satisfaction across different phases in adult life. We discuss the theoretical implications for the foundations that may underlie the link between personality and satisfaction in various life phases.
