A Natural Helper Intervention to Address Disparities in Parent Child-Interaction Therapy: A Randomized Pilot Study

Parent-child interaction therapy (PCIT) is an effective intervention to address child externalizing behaviors. However, disparities in access and retention are pervasive, which relate to the availability of PCIT in low-income communities, inadequate workforces to provide culturally appropriate care, and distrust in services due to systemic discrimination. This study incorporated natural helpers who had been trained as community health workers into PCIT delivery to improve disparities in engagement and outcomes.

Families from three low-income, predominately Latino/a/x and Black neighborhoods in Miami qualified for services if they had a child aged 2-8 with clinically elevated externalizing behaviors. Families were randomly assigned into either Standard-PCIT group (N = 30 families; 80% boys, 57% Latino/a/x, 27% Black) or a PCIT plus Natural helper (PCIT+NH) group (N = 51 families; 66% boys, 76% Latino/a/x, 18% Black). Families in the PCIT+NH group received home visits and support addressing barriers to care from a natural helper. Path analyses within an intention-to-treat framework examined group-differences in treatment engagement, child behavior, and parenting skills and stress.

Families in both groups demonstrated large improvements in child externalizing behavior, caregiver stress, and parenting skills from pre-to-post-treatment. Externalizing behavior improved significantly more in the PCIT+NH group compared to the Standard-PCIT group. There were no significant group differences in parenting skills or caregiver stress. Though differences in engagement were not significant, the PCIT+NH group had a small effect on treatment retention.

Natural helpers may help to address structural barriers that systematically impact communities of color, apply treatment in naturalistic environments, and promote improved treatment outcomes.
