Social ecology moderates the association between self-esteem and happiness

Previous research has found cross-cultural differences in the strength of the association between self-esteem and happiness. We propose that this difference can be explained by relational mobility, or the degree to which options exist in the given socio-ecological context for relationship formation and dissolution. In Study 1, we found that the association between self-esteem and happiness was stronger among American participants than among Japanese participants. As predicted, this cultural difference was explained by the difference in relational mobility. In Study 2, we found that the association between self-esteem and happiness was stronger among Japanese living in relationally mobile regions than among Japanese living in less mobile regions. In Study 3, we manipulated relational mobility and demonstrated that the thought of living in a relationally mobile society caused individuals to base their life satisfaction judgments on self-esteem. Overall, our research demonstrates the utility of examining cultural differences from a socio-ecological perspective.

► We attempt to explain the differences in the determinants of happiness between cultures.
► We hypothesize that structure of social ecology affects determinants of happiness.
► High relational mobility strengthens the link between self-esteem and happiness.
► Three multi-method studies confirmed this hypothesis.
