The Community Healthy Marriage Initiative (CHMI) is a key component of the demonstration strategy of the Administration for Children and Families (ACF) to determine how public policies can best support healthy marriages. Two concepts underlie the CHMI strategy. One is that community coalitions can be an effective vehicle for developing a range of healthy marriage and healthy family activities, including classes that build relationship skills, but also partnerships with clergy and others, celebration days, and media messages about the value of marriage and healthy families. The second is that communities with a critical mass of such activities can exert positive family impacts on individuals and couples directly through their participation in classes and other services and indirectly through their interactions with friends, family, and others in the community who were themselves influenced by a local marriage-related activity sponsored by the local coalition. The goals of the 1115 healthy marriage initiatives are to achieve child support objectives through healthy marriage activities. This report focuses on the role of community coalitions in supporting healthy marriage activities and presents a description and analysis of the early implementation of the section 1115 child support waiver1 demonstration in Nampa, Idaho, a city of nearly 70,000 people. This report provides evidence that a local community coalition can leverage sufficient resources to stimulate a substantial amount of marriage-related and family relationship activities at a modest cost. This report does not address the question of impacts on marriage or child support outcomes of participants or others in the community. Healthy Families Nampa’s initial operations should be viewed as a pilot of community approaches to healthy marriage that, given time and available funding, could develop into a full-scale community healthy marriage initiative (CHMI). The Nampa community initiative, called the Healthy Marriage, Responsible Fatherhood Nampa Community Demonstration Initiative, was awarded a Child Support Enforcement Demonstration Section 1115 Federal waiver in May 2003 and began operations shortly thereafter. Healthy Families Nampa (HFN) is the coalition of faith-based and other community partners that is running the initiative. To examine how the Nampa community initiative became operational, how it formed and maintained community coalitions, and how it began operations, RTI/Urban Institute staff collected information from several sources, including a site visit in January 2005, monthly project status update calls, a focus group with recent recipients of local marriage- and parenting-education services, and data on individuals referred to HFN services (drawn from HFN’s Management Information System [MIS]). Because HFN is still at a relatively early stage of operation, and some of the report’s material is based on operations as of January 2005, readers should view this report as providing a snapshot of the constantly evolving and developing community initiative.
