This study examined the potential mediating roles of coparenting and parenting practices on the relationship between marital status and young adult adjustment in intact and divorced or separated families. Participants were 340 undergraduate students from intact and divorced or separated families who completed questionnaires that tapped a range of adjustment factors (mental health, fear of intimacy, work ethic, self-esteem, delinquency) along with coparenting and parenting practices. Data were analyzed via structural equation modeling. Results suggest that coparenting and parenting practices, including parental hostility, parental cooperation, mothering, and fathering, are important partial mediators of the relationship between marital status and young adult adjustment. Intervention and legal implications are discussed.
