This study aims to determine the relationship between authenticity and subjective vitality among university students in Turkey. The study was carried out with 284 university students (164 female, 120 male, M-age = 19.91 years, SD = 1.79, and age range: 17-30). Participants completed the Turkish version of the Authenticity Scale and Subjective Vitality Scale. To test the relationships between authenticity and subjective vitality, Pearson product-moment correlation and hierarchical regression analyses, as well as bootstrapping, were applied. In the correlation analysis, subjective vitality was negatively associated with the accepting external influences and self-alienation dimensions of authenticity and positively associated with the authentic living dimension of authenticity. The hierarchical regression analysis involved authentic living, self-alienation, and accepting external influence as predictors of subjective vitality and accounted for 31% of the variance in subjective vitality; results were discussed in related previous authenticity and subjective vitality literature.
