Each year, the HomVEE review team screens all new citations identified through the literature search for relevance. The team screens out studies for the following reasons:
- Home visiting was not the primary service delivery strategy.
- The study did not use an eligible design (randomized controlled trials, quasi-experimental designs, and implementation studies).
- The study of the program did not report results for an eligible target population: pregnant women or families with children from birth to kindergarten entry (that is, up through age 5) served in a developed-world context.
- The study did not examine any outcomes in the eight eligible outcome domains (maternal health; child health; child development and school readiness; reductions in child maltreatment; reductions in juvenile delinquency, family violence, and crime; positive parenting practices; family economic self-sufficiency; and linkages and referrals).
- The study did not examine a named home visiting program model.
- The study was not published in English.
- The study was published before 1989 for the initial search or 1979 for the focused search on prioritized program models.
