Intergenerational Transmission of Trauma: The Mediating Role of Parenting Styles on Toddlers' DSM-Related Symptoms

Although the intergenerational transmission of trauma has been well documented, the pathways by which trauma symptoms are passed between parents and children remain unclear. This study examined the mediating role of parenting styles in the transmission of maternal trauma to children. Participants were a sample of 105 mothers of toddlers (18–30 months old). Mothers who had experienced interpersonal trauma were more likely to have an authoritarian parenting style, including verbal hostility, physical coercion, and low nurturance. Verbal hostility especially predicted more prevalent and increasing toddler symptoms associated with affective, hyperactive, and oppositional defiant disorders. Thus, the verbal hostility component of authoritarian parenting could serve as a major intergenerational pathway between maternal trauma and early child symptoms.
