You may request a re-review if you think the HHS criteria has been misapplied, information is missing, or there are errors on the HomVEE website. These concerns should be described in detail and submitted to: hvee@mathematica-mpr.com. If HHS approves the request, a re-review team made up of members external to the original contractor who were not involved in the original review will conduct a new, independent review. For more information on the re-review process, see Requests for Reconsideration of Evidence Determinations.

In addition to the main HomVEE review, the HomVEE team conducted a review of models that were implemented in tribal communities or included substantial proportions of American Indian Alaska Native families in the study samples. The results of this review are presented in a separate reports entitled, “Assessing the Research on Home Visiting Program Models Implemented in Tribal Communities Part 1: Evidence of Effectiveness“ and “Assessing the Research on Home Visiting Program Models Implemented in Tribal Communities Part 2: Lessons Learned about Implementation and Evaluation.“ These reports can be accessed on the Publications tab.

Although study samples included in the HomVEE review are quite diverse, most of the high- and moderate-quality impact studies aggregate the results across racial/ethnic groups. Thus, the available evidence does not indicate whether these models are more or less effective with one group or another. Further, sample sizes of most studies do not provide sufficient statistical power to detect effects for specific racial/ethnic groups. In other words, even if there are sizeable effects of the intervention for a particular racial/ethnic group, these may not be detected because of small sample sizes for that group. HomVEE only reported subgroup results for findings that were replicated in two different analytic samples; replication provides greater confidence that findings were not observed by chance. None of the models reviewed by HomVEE had subgroup findings for specific racial/ethnic groups that were replicated in two different samples. More information on study characteristics can be found for each model report accessed through the Research tab.

Several of the models that meet the HHS criteria for an “evidence-based early childhood home visiting service delivery model” have been studied with families from a mix of urban and rural communities. Results for families from rural and urban areas were aggregated across groups. Thus, the available evidence does not indicate whether these models are more or less effective with families from rural or urban communities. More information on study characteristics can be found for each model report accessed through the Research tab.

Overall, the high- and moderate-quality impact studies included in the HomVEE review have diverse study samples that include families from a range of racial/ethnic groups and families with low incomes. The majority includes families from multiple racial/ethnic groups and all of the samples include low-income families. More information on study characteristics can be found for each model report accessed through the Research tab.

No. The HomVEE project does not have consistent information about research underway on home visiting models. States seeking information about research in process on specific models should contact the model developer or purveyor directly.

Yes. Detailed information about preterm birth, low birth weight, and newborn outcomes that were measured can be found in the Child Health section of the Effects Shown in Research section of each model report. The reports can be accessed through the Research tab. All outcomes in the Child Health domain combined across models can be accessed through the Outcomes tab.
