This study will examine the efficacy of a dyadic therapy intervention for mothers who have histories of adverse events (e.g., history of family violence, partner violence, family conflict, and/or childhood trauma, including abuse/neglect) and their very young children (ages 0-5 years), with the goal of demonstrating how an evidence supported, community-based and/or hospital-based therapeutic intervention may help reduce exposure to trauma and incidents of child maltreatment, improve parental stress and mental health, and secure parent-child attachment.
