This study aimed to explore the factors that affect on their positive psychological well-being among older adults. Especially, it tried to examine how their volunteering work experiences affect their level of psychological well-being. The data of the Volunteerism among Older Adults between U.S. and South Korea by the Center for Excellence in Aging Services and Community Wellness (CEASCW) in 2010 were used for this purpose. 274 older volunteers in South Korea were adopted as the data of this study. This study conducted the descriptive analyses, correlation analysis and multiple regression analyses to explore the determinants of their psychological well-being. In the regression model, by adding socioeconomic characteristics, two antecedent factors-work assignment and personal efficacy were statistically significant. This result suggests that older volunteers with higher level of work assignment achieved and satisfaction with personal efficacy are more likely to present the higher status of well-being in later life. Therefore, volunteer agency should be took for older volunteers to consider the determinants of satisfaction in order to increase the retention rate of volunteering and improve psychological well-being in later life.
