This study sought to examine the association between parental behavior indicative of overinvolvement and control and young adult child self-identity, namely self-efficacy and psychological entitlement. Participants in this study were 339 parent-young adult child dyads who completed survey measures of family environment, parenting, family communication, and family satisfaction. Young adults also completed measures of self-efficacy and entitlement. Results showed that balanced family adaptability and cohesion, open family communication, and authoritative rather than authoritarian parenting, were positively associated with parents’ and young adults’ family satisfaction. Parental behavior that emphasized control over the child was associated with diminished self-efficacy and exaggerated psychological entitlement in young adult children. The relationship between these two classes of variables was amplified by open parent-child communication.
