Were maternal/infant home visiting models, not just early childhood, included in the review?
Yes. Several models enroll women during pregnancy and aim to improve maternal health, infant health, and birth outcomes. Detailed information about each model’s theoretical model, target population, and target outcomes can be found on the model overview page of the implementation profile. Profiles can be accessed through the Implementation tab. Detailed information about maternal and child health outcomes can be found in the Effects Shown in Research tab in each model report. The reports can be accessed through the Research tab. That tab also has a search function that allows the user to filter the models by target population.
Is there any consideration given to those models that may not demonstrate a large impact due to the sample being difficult to treat (parents with severe mental illness, etc.)?
The HHS criteria do not consider the magnitude of impacts in determining whether a model has evidence of effectiveness.
Even though magnitude was not considered in the HHS criteria, HomVEE reported standard effect sizes on the website when they were available in the studies or the HomVEE team had sufficient information to calculate them. Effect sizes can be found in the Effects Shown in Research section of each model report. The reports can be accessed through the Research tab.
