Introduction
A portion of the federal funds that support home visiting for mothers and families with young children are designated specifically for supporting home visiting in tribal communities. Therefore, policymakers and program administrators need to know what research has learned about home visiting in these communities. To assess the evidence of effectiveness of models that have been implemented in tribal communities, the Home Visiting Evidence of Effectiveness (HomVEE) review conducted a targeted systematic review. The review included studies of home visiting models implemented in tribal communities. Part 2 of this report describes key lessons learned from home visiting models implemented in tribal communities, including gaps in the research literature that create challenges for assessing effectiveness and suggestions for strengthening future research in this area. The review was originally released in February 2011; the updated version includes results from studies released through the end of 2015 or received through the HomVEE call for studies that closed in early January 2016.
