According to theoretical knowledge and previous research findings on the relationship between the quality of family relationships and the understanding and expectations in romantic relationships, this paper seeks to determine whether the dynamics of parental conflicts in childhood contribute to the formation of beliefs and types of attachment in these relationships. 162 respondents participated in the research, who voluntarily and anonymously filled in the survey questionnaire. It contained The Scale of Children's Perception of Interparental Conflict (Grych et al., 1992; Burić & Macuka, 2013) and the Questionnaire of Experiences in Close Relationships (Brennan et al, 2000). The relationship between the dimensions of parental conflict and the prevalence of anxious attachment styles of young adults in romantic partnerships was examined. Of the nine dimensions of conflict, resolution, triangulation, and perceived threat proved to be the most statistically significant. Resolution and perceived threat are significant predictors of anxiety-resistance attachment, and resolution and triangulation are predictors of anxiety-avoidance attachment. Frequency and intensity, usually the expected dimensions in terms of significance in conflict, did not statistically stand out as predictors of anxiety attachment styles. Also, the results obtained by t-test of independent samples showed that in both sexes the anxiety-resisting attachment style is represented to the same extent, but that male participants are more prone to anxiety-avoidance attachment style than female participants.
