Parent–Child Interaction Therapy is an evidence-based treatment for young children (aged 2.5–7 years) with externalizing behavior problems. Since its development, Parent–Child Interaction Therapy has been applied to a wide array of childhood problems and has a significant evidence base for families with histories of child physical abuse. The current study extended the existing literature by testing the effectiveness and feasibility of Parent–Child Interaction Therapy in an urban domestic violence shelter with community-based clinicians delivering the treatment. Seven clinicians implemented Parent–Child Interaction Therapy with parent–child dyads, which included 21 preschool (M = 4.57 years; SD = 1.50) children. Families completed assessments at baseline, mid-treatment, and post-treatment. Nine families completed Parent–Child Interaction Therapy (43 %). Completion of Parent–Child Interaction Therapy was associated with improved child behavior, parenting practices, and mental health symptoms. Considerations for treatment delivery and future directions are discussed.
