Evidence of Model Effectiveness

This model does not meet the criteria established by the Department of Health and Human Services (HHS) for an “evidence-based early childhood home visiting service delivery model” for the general population or for tribal populations.


Model Description

Implemented in Australia, Mothers’ Advocates in the Community (MOSAIC) aimed to reduce intimate partner violence (IPV) and depression and improve mothers’ health, well-being, and attachment to their children. It targeted women who were pregnant or had a child age 5 or younger and reported experiencing IPV or psychosocial distress. The program included 12 months of weekly home visits and regular telephone calls with nonprofessional peer mothers, known as mentor mothers. Mentor mothers provided safety and self-care strategies, parenting support, and information and referrals for community resources (including family violence services). For more information, please read the Model Overview.
