This study attempted to verify the effects of factors that influence the expectations of successful aging of Generation X(ages 45-55) who will be incorporated into the elderly generation within the next 10 years. To this end, a nationwide survey was conducted on 200 people in the 45-55 age group. The collected response data were analyzed through multiple and hierarchical regression analyses. The analysis results were as follows. First, it was found that Generation X's individualistic tendencies negatively affected the expected value of successful aging. On the other hand, Generation X's collectivist tendencies were a factor that positively influenced the expected value of successful aging. Second, the expected value factors of successful aging, which are most effective for Generation X, were found to be self-esteem, self-efficacy, and leisure commitment factors. Third, it was found that the level of use of the SOC strategy, known as a useful strategy for successful aging, harmed Generation X's perception of successful aging. Fourth, collectivism, self-esteem, self-efficacy, and leisure commitment, which appeared as factors that increase the expected value of successful aging of Generation X, were not mediated through SOC strategies but were found to have a direct effect. This result implies that it is necessary to establish a new successful aging strategy for Generation X.
