This brief describes the types of adaptation that are already underway in healthy marriage programs to address culturally diverse populations and provides examples. It identifies some of the key issues and challenges involved in making marriage education relevant for and accessible to culturally diverse and economically disadvantaged populations. It begins by explaining the marriage education field prior to 2000 and the rapid increase in the number of programs as a result of the advent of federal and State government funding. Changes in programs as they adapted to address the demographic diversity of participants are described and include adaptations to address differences in marital and family status, income and education, and cultural and ethnic differences. The need for adaptations at the instructional and organizational levels is discussed, as well as the adaptations needed to address domestic violence situations. Examples of how different programs have adapted are provided and include program and curriculum adaptations for serving African-Americans, Latinos, Native Americans, and refugees. Federal demonstrations and curriculum adaptations are highlighted, as well curricula developed independent of federal demonstrations. 6 boxes and 14 references.
