You may request a re-review if you think that (1) in applying the criteria to determine whether a particular model is evidence based, HomVEE made one or more errors; and (2) if these errors were addressed, the model would be evidence based. Specifically, you may request reconsideration of the evidence-based determination based on misapplication of the HHS criteria, missing information, or errors on the HomVEE website. These concerns should be described in detail and submitted to: HomVEE@acf.hhs.gov. Pending approval from HHS, an independent re-review team will conduct a new review of the manuscript(s) in question. Re-reviews are conducted using the procedures and standards in place at the time of the original review. For more information on the re-review process, see Chapter 2 of the Version 2 Handbook of Procedures and Evidence Standards on the Methods and Standards section of the website.

In addition to the main HomVEE review, HomVEE periodically updates 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 two-volume report and related research briefs. These reports can be accessed on the Tribal Home Visiting page.

Although study samples included in the HomVEE review are quite diverse, most of the manuscripts about high- and moderate-quality impact studies aggregate the results across racial/ethnic groups. Thus, the available evidence generally does not reveal whether these models are more or less effective with one group or another.

Further, the sample sizes of most studies may not provide sufficient statistical power to detect effects for specific racial/ethnic subgroups. 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 subgroup.

Because HomVEE’s mission is to identify evidence-based models, and HHS’ criteria require replication before subgroup research can be part of the evidence base, the annual review only reports findings from impact research on replicated subgroups. Replication provides more confidence that findings were not observed by chance. HomVEE uses the same set of standards to rate the quality of research for all findings on a replicated subgroup. For example, if the subgroup replication straddled the timing of an update to HomVEE standards, HomVEE would review both sets of subgroup findings using the newest standards (even if other, full-sample findings from the older manuscript were reviewed using older HomVEE standards).

HomVEE recognizes that the effects of models for different populations is of interest to the home visiting field. Although HomVEE only reports findings for replicated subgroups, HomVEE lists the subgroups examined in each manuscript beginning with its 2021 annual review. HomVEE does not report details on the findings or the quality of the study design until the subgroup is replicated.

More information on study characteristics, including the race/ethnicity of a study sample, can be found for each manuscript about high- or moderate-rated study on a model via the Information about research reviewed tab in any Model Effectiveness Research Report. If a model has been tested with a replicated subgroup, HomVEE summarizes the subgroup findings as part of that model’s effectiveness research report.

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 in a mix of urban and rural communities. Results for families from rural and urban areas are generally aggregated across groups. More information on study characteristics, including the setting, can be found for each manuscript about high- or moderate-rated study on a model via the Information about research reviewed tab in any Model Effectiveness Research Report.

Overall, the manuscripts about 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 of manuscripts include families from multiple racial/ethnic groups and most of the samples include families with low incomes. More information on study characteristics can be found for each high- and moderate-rated manuscript about a model, via the Information about research reviewed tab in any Model Effectiveness Research Report.

No. HomVEE does not have consistent information about research underway on home visiting models. Stakeholders seeking information about research in progress on specific models should contact the model developer directly.

Information on implementation of models is available in the implementation profiles. The implementation profiles give an overview of the model and information about developers’ input on the following: prerequisites for implementation, training, materials and forms, program costs, and model contact information. These profiles can be accessed on the Model Implementation Summary Report page.
