Introduction. The separation of an adult child from parents implies the process of changing the relationship with parents towards greater equality, parity and equal relations between parents and children. The effective completion of separation means that young people achieve personal autonomy. A disrupted or incomplete separation process results in difficulties in building one's own marital and child-parent relationships, the presence of anxiety and insecurity in marriage, and the inability to build sincere, trust-based relationships. The purpose of the study is to study the peculiarities of the interaction of young spouses with varying degrees of separation from the parental family. Materials and methods: the study involved 100 people, men (N=50) and women (N=50), aged 25 to 45 years with marital experience from 1 to 5 years. The following methods were used: the PEA questionnaire – understanding, emotional attraction, authority (developed by A.N. Volkova, modified by V.I. Slepkova); the questionnaire “The nature of interaction between spouses in conflict situations” (Yu.E. Aleshina, L.Ya. Gozman); a test to determine psychological and energy separation from parents (Bondarenko T.A.). The mathematical processing of the obtained data was carried out using the non-parametric mathematical Kruskall-Wallis method, using the SSPS statistical analysis program. Results: understanding, emotional attractiveness and authority (respect) prevail in the relationship between the spouses. Conflicts in married couples are most often associated with jealousy, differences in attitude towards money, and violation of role expectations. In a conflict situation, most spouses most often use a positively active type of reaction, about a third of spouses behave passively, slightly less than a third show negative activity. Most spouses have an average separation level, a third of the sample is high, and about a third is low. In the relationship of spouses with a high level of separation from the parental family, the following are more often observed: understanding, emotional attraction, authority. Spouses with a low level of separation from their parent family are characterized by problems and conflicts over relationships with relatives and friends, disagreements on parenting, a desire for autonomy, violation of role expectations, and a mismatch in ideas about norms of behavior. Spouses who have a low level of separation from their parents often face difficulties in building harmonious family relationships and are unable to respect each other's opinions. Conclusion. The hypothesis that the characteristics of interaction in a married couple differ among spouses with varying degrees of separation from the parent family.
