Directionality of the relationship between social well-being and subjective well-being: evidence from a 20-year longitudinal study.

PURPOSE: Self-determination theory suggests that psycho-social well-being prospectively predicts subjective well-being. In contrast, the broaden-and-build theory of positive emotions suggests that subjective well-being has a positive impact on subsequent levels of psycho-social well-being. The present study sought to empirically disentangle the directionality of the relationship between subjective well-being and social well-being over time.

METHODS: The study used three waves of survey data, with intervals of 10 years, from the Midlife in the United States (MIDUS) project, a representative longitudinal panel study of American adults (N = 2732). Cross-lagged panel modeling was used for data analysis.

RESULTS: The results revealed that social well-being predicted increases in subsequent subjective well-being, whereas subjective well-being did not prospectively predict social well-being. Social well-being also demonstrated more stability over time than did subjective well-being.

CONCLUSION: These findings suggest that optimal social functioning is more likely to be an antecedent to subjective well-being, not the other way around. The results are consistent with predictions guided by self-determination theory.
