Evidence of Program Model Effectiveness

This program model meets the criteria established by the Department of Health and Human Services (DHHS) for an “evidence-based early childhood home visiting service delivery model” for the general population, but does not meet the criteria for tribal populations.

Program Model Description

Early Start is a voluntary home visiting program designed to improve child health, reduce child abuse, improve parenting skills, support parental physical and mental health, encourage family economic well-being, and encourage stable, positive partner relationships. Early Start was designed to be a mainstream program, targeting at-risk families with newborns and children up to age 5. However, the developers took steps to ensure that the model would also be culturally responsive to the Māori, an indigenous population of New Zealand. Home visitors deliver services at varying levels of intensity depending on the family’s needs. Families with the highest needs receive up to three hours of home visits and indirect contact per week (level 1), families with moderate needs receive up to three hours of home visiting every two weeks (level 2), and families with lower needs receive up to one hour of home visiting monthly (level 3). The fourth and final level of services includes up to one hour of contact every three months. Home visitors in consultation with their supervisors determine when a family is ready to progress to the next level. For more information, please read the Program Model Overview.

*Note: DHHS has decided to report all findings from high and moderate rated studies that focus on a tribal population. Typically, HomVEE reports subgroup findings if such findings are replicated in the same outcome domain in at least two studies using different analytic samples.

Please read Describing Effects for more information on these categories. Only results from studies that meet the standards for the high or moderate ratings are included above.

Criteria Established by the Department of Health and Human Services

 Early Start (New Zealand) - Full SampleEarly Start (New Zealand) – Māori subgroup
Information Based on Comprehensive Review of All High- and Moderate-Impact Studies for this Model
High- or moderate-quality impact study? YesYes
Across high- or moderate-quality studies, favorable impacts in…
 
   at least two outcome domains within one sample
 
   OR
 
   the same domain for at least two non-overlapping samples?
YesYes
Favorable impacts on full sample? YesYes
Any favorable impacts on outcome measures sustained at least 12 months after program enrollment?a YesYes
One or more favorable, statistically significant impact reported in a peer-reviewed journal?a YesNo

aThis information is reported for all program models, but the requirements for sustained findings and inclusion in a peer-reviewed journal only apply to models for which all findings are from randomized controlled trials.
