CPP is an intervention model for children aged 0-6 who have experienced at least one traumatic event and/or are experiencing mental health, attachment, and/or behavioral problems, including posttraumatic stress disorder. The treatment is based in attachment theory but also integrates psychodynamic, developmental, trauma, social learning, and cognitive behavioral theories. Therapeutic sessions include the child and parent or primary caregiver. The primary goal of CPP is to support and strengthen the relationship between a child and his or her caregiver as a vehicle for restoring the child's cognitive, behavioral, and social functioning. Treatment also focuses on contextual factors that may affect the caregiver-child relationship.
