CPP helps to change maladaptive behaviors, support developmentally appropriate interactions, and guide the child and mother in creating a narrative of the trauma together while working towards resolution.

Unique/Innovative Characteristics
  • Focus on prenatal trauma and impact of trauma on infants and young children
  • Focus on child-parent relationship as focus of treatment
  • Adaptations of CPP include Perinatal CPP and a co-parenting model that involves fathers

Population Adaptations:

Age range of children:

Prenatal through 5 years old

Parent/adult caregiver included in intervention:

Child-parent psychotherapy includes the parent in the treatment; in most cases, the non-offending parent. Offending parents are included in the intervention if an initial assessment shows that treatment can be offered safely and is likely to be effective.

Ethnic/racial and other groups served:

All ethnic/racial groups depending on linguistic capacity. In one randomized control trial, all children were Latinos; in two trials the majority of mothers were African American. The program has linguistic expertise in Spanish and Portuguese and a high proportion of the children and families served are monolingual Spanish speakers.

Specific cultural adaptations:

The program cultivates cultural competence by becoming informed about values, childrearing practices, gender and role expectations, religious and spiritual beliefs, and other culturally specific dimensions influencing the functioning of the families.

Languages available:

English, Spanish, Portuguese, French


Theoretical basis:

Integrative approach rooted in psychodynamic and attachment theory that also incorporates premises and practices from trauma clinical research, developmental psychopathology, cognitive-behavioral therapy, and social learning theory.

Evaluation Studies:

In a randomized controlled trial, 75 multiethnic (38.7% mixed ethnicity, 28% Latino, 14.7% African American, 9.3% white, 6.7% Asian) preschool-age child-mother dyads were randomized to CPP or case management plus community referral for individual treatment. The child-mother dyads randomized to CPP attended 60-minute sessions for 50 weeks (mean number of sessions attended was 32.09).

Six months after the one-year treatment period ended, children who participated in CPP had significantly fewer behavior problems and their mothers had significant improvement in severity of psychiatric symptoms compared to children and mothers who received case management and community referrals (control group).

Results for the randomized controlled trial described above at the end of the one-year intervention were:

  • Children who received CPP had fewer total behavior problems, decreased traumatic stress symptoms, and were less likely to be diagnosed with traumatic stress symptoms compared to children in the control group
  • Mothers receiving CPP showed fewer posttraumatic stress avoidance symptoms compared to mothers in the control group
