This report summarizes the results of a qualitative interview-based sub-study conducted among a sample of 74 program group mothers who received home visiting from evidence-based programs that were part of MIHOPE. It builds upon earlier reports published from MIHOPE, particularly the implementation research report, which presented findings from qualitative interviews with home visitors about how they describe their work and relationships with mothers. The overarching goal of the in-depth interviews with mothers was to shed light on why and how families engage for the time they do, including the role of the home visitor-parent relationship in a family’s engagement.  (author abstract)
