Federal policies are encouraging states to strengthen marital relationships among low income populations as a strategy for improving child well being. Conducted to inform the design of marriage programs, this study examined the environment, setting, interventions, and client characteristics of existing services for couples. Twenty-eight visits were made to public health agencies, mental health programs, community centers, social service agencies, and religious organizations. The report provides an overview of marriage programming and describes the structure of the programs studied. Benefits and challenges for implementation and expansion are highlighted. The analysis also outlines considerations for evaluation, including the diversity of environments, the context of other services, lack of knowledge about evaluation, the levels of practitioner experience, definitions of marriage interventions, and monitoring transient populations. The study recommends collaboration between experienced marriage service providers and agencies with knowledge of low-income families to develop new programs and expand exiting initiatives. 3 figures, 6 tables.
