Inter‐ and Intraindividual Relations Between Agentic, Communal Self‐Enhancement and Hedonic, Eudaimonic Well‐Being: Feedback and Mediation Mechanisms

INTRODUCTION: Researchers seldom consider the interplay between self-enhancement (SE) and well-being at both inter- and intraindividual levels. Previous studies have primarily focused on agentic SE and hedonic well-being, often neglecting communal SE and eudaimonic well-being. This study aims to address these gaps by examining the reciprocal relationship between both agentic and communal SE and both hedonic and eudaimonic well-being. Self-esteem is identified as a potential mediator in these relationships at both inter- and intraindividual levels. METHOD: = 24.25, 75% female) responded to smartphone prompts four times daily for 10 days, yielding 5925 observations. Data were analyzed with Dynamic Structural Equation Modeling. RESULTS: At the intraindividual level, stronger SE predicted increased hedonic and eudaimonic well-being within a short period (about 4 h). This enhanced well-being, in turn, was related to stronger SE, creating a positive feedback loop. At the interindividual level, higher agentic and communal SE correlated with greater well-being. Self-esteem mediated the reciprocal associations between SE and well-being at both levels. CONCLUSION: These findings offer new insights into the dynamics of SE and well-being, supporting the positive link between SE and well-being in everyday life, emphasizing the mediating role of self-esteem across different analysis levels.
