Understanding the Dynamics of Hedonic and Eudaimonic Motives on Daily Well-Being: Insights from Experience Sampling Data

Previous studies have consistently found that hedonic and eudaimonic motives positively predict subjective well-being. In this study, we emphasized the importance of considering curvilinear effects alongside main effects and interactions to fully understand these relationships. Using polynomial regression models, we examined the relationships between hedonic motives, eudaimonic motives, and subjective well-being. To examine both trait-level and momentary-level relations with well-being, we used experience sampling methodology to collect real-time data from 161 participants over a 7-day period. Our findings suggested that engaging in activities towards fulfilling both motives was associated with positive experiences, and individuals with high levels of hedonic and eudaimonic motives in their daily lives generally reported higher subjective well-being. Nevertheless, we also identified negative interaction effects between both motives on subjective well-being, which imply that there may be a limit to the positive contributions of combinations of both motives to subjective well-being. We discuss the implications of our findings for understanding the nuanced relationships between hedonic and eudaimonic motives and subjective well-being.
