Investigating the sources of happiness dates back to ancient times and has an important share in today's mental health research. Subjective well-being is included in the scientific definitions of happiness. Although there are many studies on subjective well-being, studies examining this concept in a developmental context are still limited. This study aims to examine the role of personality, values, and social relationships in explaining subjective well-being in adolescents and emerging adults. Research data related to the independent variables of the research Five Factor Personality Inventory, Portrait Values Questionnaire, Network of Relationships Inventory Short Form; data on dependent variables were collected using the Satisfaction with Life Scale and the Positive-Negative Affect Scale. The sample of the study is convenient sampling and data were collected from total of 716 participants, consisting of adolescents (n=372) and emerging adults (n=344). The collection of data was based on a voluntary basis. After testing the data for normal distrubition and there was no multicollinearity between variables, the main analysises were run. Pearson Product-Moment Correlation Coefficient and Hierarchical Multiple Regression Analysis were performed. When the subjective well-being literature is examined, it is seen that the subjective well-being levels of individuals may differ according to gender; therefore, gender was assigned as the control variable in this study. Findings showed that neuroticism in both adolescents and emerging adults, conservatism in adolescents, self-enhancement in emerging adults, and positive relationship with mother both in adolescents and emerging adults contributed to subjective well-being. In this study, social relations are limited to mother and closest relations. It is thought that the inclusion of relationships with different people in the social networks of individuals in future studies is important for a better understanding of the social determinants of subjective well-being.
