The Mediator Role of Subjective Vitality in the Relationship between Psychological Flexibility and Life Satisfaction in Adolescents

The purpose of this study was to examine the mediating role of subjective vitality in the relationship between psychological flexibility and life satisfaction in adolescents. Data were collected using the Satisfaction with Life Scale, Psychological Flexibility Scale, and Subjective Vitality Scale. A total of 392 high school students aged between 13 and 18 participated in the study. Of the participating students, 223 (56.9%) were female and 169 (43.1%) were male students. According to the results obtained in the study, there is a positive significant correlation between psychological flexibility and life satisfaction. The other result of this study is that there is a significant positive relationship between psychological flexibility and subjective vitality. In addition, the results of the study revealed that subjective vitality mediates the relationship between psychological flexibility and life satisfaction. This result suggests that both subjective vitality and psychological flexibility can be viewed as sources of high life satisfaction. In other words, psychological flexibility predicts subjective vitality, and consequently, increased subjective vitality predicts higher life satisfaction. These findings suggest that, similar to psychological flexibility, subjective vitality could significantly contribute to enhancing adolescents' life satisfaction. This result suggests that both subjective vitality and psychological flexibility can be viewed as sources of high life satisfaction. This study is important both because there is no other study on this subject in the literature and because it contributes to mental health professionals in developing intervention approaches for adolescents.
