Brief Report Differential Relationships of Hedonic and Eudaimonic Well-Being with Self-Control and Long-Term Orientation 1 MOHSEN JOSHANLOO * Keimyung University VELJKO JOVANOVI  C University of Novi Sad JOONHA PARK Graduate School of Management, NUCB Business School Abstract: This study sought to explore differential relations between the hedonic (life satisfaction, negative affect, and positive affect) and eudaimonic (psychological well- being and social well-being) components of well-being and five criterion variables: long-term planning, self-control, sensation-seeking, grit, and intellectualism. The study used a sample of 1,310 Korean adults (M age = 40.024 years, SD age = 10.922 years). It was predicted and found that the criterion variables of the study had stronger associa- tions with eudaimonic well-being than hedonic well-being. The results indicate that eudaimonic well-being is more consistent than hedonic well-being with a long-term emphasis on skill-building and striving for future goals (as opposed to immediate gratification). Key words: well-being, self-control, sensation-seeking, grit, intellectualism. Hedonic well-being is defined by pleasure or affective experience and is often operatio- nalized as the presence of positive emotions and life satisfaction, and the absence of negative emotions (Diener, Lucas, & Oishi, 2018). Eudaimonic well-being is defined as the pres- ence of personal and social skills and abilities (e.g., meaning in life, a sense of continued per- sonal growth, and social contribution) that con- tribute to optimal psychosocial functioning (Ryff, 2018). Hedonic and eudaimonic well- being are theoretically distinguishable and are based on different philosophical traditions (Delle Fave, 2014). Moreover, factor analytic studies suggest that hedonic and eudaimonic well-being are related yet distinct factors (for reviews, see Joshanloo, 2019a). Although some philosophers have argued that life satisfaction can also be considered as a component of eudaimonia (see Feldman, 2008), empirical findings have consistently demonstrated that life satisfaction is a hedonistic component (for a review, see Joshanloo & Weijers, 2019). Not much is known about these concepts’ dif- ferential nomological networks. Yet, the weight of existing evidence, although admittedly lim- ited, does suggest that the two concepts have differential relationships with external criteria *Correspondence concerning this article should be sent to: Mohsen Joshanloo, Department of Psychology, Keimyung University, 1095 Dalgubeol Boulevard, Dalseo-Gu, Daegu 42601, South Korea.
