The Administration for Children and Families (ACF), Office of Planning, Research, and Evaluation, part of the DHHS, in collaboration with the Health Resources and Services Administration, contracted with Mathematica Policy Research to conduct a systematic review of home visiting research. Mathematica conducted the review under the guidance of a DHHS interagency working group. This review, known as the Home Visiting Evidence of Effectiveness (HomVEE) project, determines which home visiting program models have sufficient evidence to meet the DHHS criteria for an "evidence-based early childhood home visiting service delivery model." The HomVEE review only includes program models that use home visiting as the primary mode of service delivery and aim to improve outcomes in at least one of the eight domains specified in the statute. These domains are (1) maternal health; (2) child health; (3) positive parenting practices; (4) child development and school readiness; (5) reductions in child maltreatment; (6) family economic self-sufficiency; (7) linkages and referrals to community resources and supports; and (8) reductions in juvenile delinquency, family violence, and crime. One component of the review focuses specifically on studies relevant to tribal communities. The review includes studies of home visiting program models implemented in tribal communities in the U.S., implemented in indigenous communities outside the U.S., or evaluated with AIAN or indigenous families and children.
