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

The Maternal Infant Health Outreach Worker (MIHOW) Program targets economically disadvantaged and geographically and/or socially isolated families with children birth to age 3. The program is designed to improve health and child development among these families. MIHOW employs parents from the local community as home visitors and role models, who educate families about nutrition, child health, and development, and positive parenting practices. The home visitors also provide links to medical and social services. For more information, please read the Model Overview.
