The study investigated the relationship between personal autonomy and subjective well-being. Also we hypothesized that there are some gender-related and age-related differences in level of these indicators. The sample: 59 young adults (29 third-year students and 30 graduates). Methods: «The general causality orientation scale» by D.A.Leontyev, O.E.Dergachyov, «Sovereignty of psychological space» by S.K.Nartova-Bochaver; Biographical questionnaire by V.R.Manukyan, N.D.Ruzaeva, «Positive and Negative Affect Schedule» by E.N.Osin, «Happiness Measures» by M.Fordyce and author’s form (modification of the DemboRubinstein scale). Results confirmed the hypothesis that there are significant positive relationships between autonomy and wellbeing. The results of regression analysis indicate the influence of personal autonomy on variables of subjective well-being. Also we found some age-related difference in results of biographical questionnaire that means that graduates are more autonomous than third-year students in everyday life. There was no significant difference between groups of males and females.
