This research aims at empirically examining the linkage between the acknowledgement of a family subsystems' functional status and tendencies in adult university student children. It focuses on the status of family functions, particularly those of family subsystems. In doing so, the study also identifies similarities in the recognition of family functions and the functional status of family subsystems. The result shows that the functions acknowledged within the family as a whole and in the family subsystem are different. In other words, while the recognition of family functions and status were common among parents, these aspects were not recognized in adult children. In addition, the study elucidates the relationship between the recognition of rules and lack of self-control in parent-child relationships. Moreover, it suggests a connection between a sense of self-condemnation and father-child relationships. Thus, the characteristics of relationships observed in family functions and the tendencies of adult children differ depending on the level of recognition within a family system or subsystem.
