Introduction. There is currently a scarcity of research examining the interconnections between the quality of young people's intra-family relationships and their value consciousness. We hypothesize that youth's level of satisfaction with the quality of relationships in their parental family (Relationship Quality Satisfaction, RQS) is associated with a specific set of structural and processual characteristics of family bonds, as well as with a complex of prosocial values. Methods. A survey involved 121 humanities students (psychology, economics) from Saint Petersburg, average age 19 years (30% male, 70% female). Assessment tools: "Family Relationships and Home" Questionnaire (Kunitsyna, Yumkina, 2015), "Value Orientations - 36" (Kunitsyna, 2010), PCRIF (Parent-Child Relationships in the Family) (Kunitsyna, 2015). Results. A definition of family relationship quality was formulated, and substantive criteria for its analysis were identified: structural (leadership and attachments); processual (family communication and activities); cognitive (collective family representations and values). Quality differences in intra-family relationships were revealed between young men and women with varying degrees of satisfaction with parental family relationships; the structure of youth value orientations and the place of RQS within it were demonstrated; 4 predictors of satisfaction with family relationships were identified: emotional attachments, mutual understanding, hospitality, and constructive conflict resolution. High satisfaction with parental family relationship quality mediates the significance of values related to trusting close relationships, creating an emotional foundation for confidence in building lasting bonds of love and friendship. Low satisfaction is associated with an increased youth focus on seeking pleasures, heightened attention to personal appearance and internal experiences. Discussion. The obtained results are consistent with Russian and international research indicating that mutual understanding and conflicts are the strongest predictors in models describing family relationship quality and factors enhancing the significance of family values. The inclusion of hospitality as a predictor in the model is practically promising, as it can be considered a resource for the family system.
