The pursuit of goals and desires can be meant as the pursuit of happiness or a sense of psychological wellbeing. The pursuing of those goals and desires is influenced by the characteristics of the environment or groups of society. This research aims to examine the differences of psychological wellbeing in three different conditions: monogamy, polygamy, and divorced family. The participants in this study were adolescents and young adults that came from three different types of the family. There were 96 participants involved in this study. Psychological wellbeing was measured by questionnaires derived from Ryff’s Psychological Wellbeing-Revisited (PWB-R) scale (1995). The data was analysed by two-way ANOVA. The results show that there was no significant main effect of sex difference (F(1, 90) = 0.57, p>0.05). There was a significant main effect of family type (F(2, 90) = 42.00, p<0.001). Such that adolescents and young adults of monogamy scored the highest in psychological wellbeing and adolescents and young adults of divorced family scored the lowest in psychological wellbeing. Adolescents and young adults of polygamy scored higher in psychological wellbeing than those of divorced family. There was no significant interaction of sex difference and family type (F(2, 90) = 0.195, p>0.05).
