This study tested young adults’ feelings of being caught between their parents as mediators of co-parental communication (i.e., supportive and antagonistic communication) and young adults’ mental health and relational satisfaction with parents. Participants included 493 young adult children from intact and divorced families. For participants from intact families, feeling caught mediated indirect effects for both supportive and antagonistic co-parental communication on satisfaction with mothers and mental health symptoms, though direct effects for supportive co-parental communication on all three outcomes remained. For participants from divorced families, however, feeling caught emerged as a mediator only of antagonistic co-parental communication and mental health symptoms. Collectively, the results suggest that feeling caught may function as a mechanism linking co-parental communication to children’s adjustment.
