Relationship satisfaction is defined in the context of social exchange theory. The quality of parenthood and social support are, like the potential predictors of satisfaction, defined in the context of self-determination theory and theory of social support. A main cause of this research was to examine the potential determinants of satisfaction in a close relationship. A survey was conducted on a convenience sample of 88 participants from 19 to 29 years old from Croatia who have a partner. Sample was formed by extracting participants who have a partner from a larger sample formed in the purpose of a pilot research for a project “HR.3.2.01-0266 Educational outcomes and careers of young people who grew up in poverty”. Also, the questionnaire for this research was made of the particular parts of instrument created for this project. Results of correlation analysis showed that significant positive correlation between quality of relationship between parents and satisfaction in a close relationship exists. The comparation of means between groups using t-test showed that no significant gender differences among relationship satisfaction exist. Third problem aimed to examine whether a quality of parenthood, quality of relationship between parents and social support during growing up, and particular characteristics of a participant, his/her partner and their relationship are significant predictors of their satisfaction in a close relationship, using the method of hierarchical regression in 5 steps. Not one of these predictors showed as a significant determinant of a satisfaction in close relationship. Taking such a results in account, the implications for future researches suggest including in research a bigger probabilistic sample, focusing on one of the types of close relationships, using one of the multidimensional measures of marital or relationship satisfaction, including different set of a potencial predictors and measures of chosen predictors.
