A child's perception of conflict between parents is crucial for a child's emotional and social development because it can shape his self-esteem, sense of security and ability to establish healthy relationships in the future. During adolescence, which is marked by numerous life changes and an increased risk of stress and mental problems, conflicts between parents can have an extremely negative impact on the psychological adjustment of children and young people. Therefore, the goal of this final paper is to examine the relationship between the perception of conflict between parents, attachment to family members, and self-esteem in a sample of young adults whose parents divorced while they were in adolescence. Differences between the perceived levels of parental conflict with regard to the presence/absence of economic difficulties after parental divorce will also be examined on this sample. The research sample consisted of 90 students (64 women and 26 men), and the following instruments were used: Scale of Children's Perception of Inter-parental Conflict (Macuka and Burić, 2013), Modified Brennan Inventory of Experiences in Close Relationships - assessment of attachment to family members (Kamenov and Jelić). , 2003) and Rosenberg's self-esteem scale (Rosenberg, 1965). A statistically significant positive correlation was found between anxiety and avoidance as a dimension of attachment on all three subscales of parental conflict - features of conflict, self-blame and threats. Individuals who perceive higher levels of parental conflict across all assessed dimensions achieve higher scores in the dimensions of anxious and avoidant attachment. A negative correlation has been established between the examined aspects of parental conflict and self-esteem; individuals who perceive higher levels of parental conflict on all assessed dimensions also have lower self-esteem. A negative correlation has been found between anxiety and avoidance as dimensions of attachment towards family members and self-esteem; higher levels of anxiety and avoidance are present in individuals with reduced self-esteem. A statistically significant difference has been established between groups that experienced and those that did not experience economic difficulties after parental divorce on the subscale of self-blame. Individuals who experienced economic difficulties, on average, achieved higher scores on the self-blame subscale compared to the group that did not experience economic difficulties after parental divorce. Therapeutic interventions could focus on strengthening the self-esteem of children from conflictual families to mitigate long-term effects on mental health.
