Relationships in the primary family are significantly associated with the psychosocial welfare of children. Children learn by observing the behaviour of their parents, so parental marital relationship will have a significant effect on the behavior of children in their own close relationships. The aim of this study was to examine the differences in the quality of close relationships among young people (relationship with parents, love partner and friends) with regard to the quality of parental relationships. The survey was conducted on a sample of 494 young people aged 18-29 from the Republic of Croatia and the following measuring instruments were applied: a Questionnaire on Quality of parental relationships and a questionnaire „The Network of relationships- Relationship Quality version“. Participants were divided into 3 groups: children of divorced parents (75 respondents), children of undivorced parents with higher quality relationship between parents (135) and children of undivorced parents with lower quality of parental relationship (284). The results showed statistically significant difference among the mentioned groups in the quality of their relationship with the parents, where it was shown that the children of undivorced parents with lower quality of parental relationships have the worst relationship with their mother and the children of divorced parents with their father, while there were not found statistically significant differences in their relationships with a love partner or a best friend.
