There is mounting research evidence that trends of increasing marital and family instability are negatively impacting children, adults, families, and communities. The research is clear: healthy relationships and healthy marriages, and resulting family stability, benefit the physical, social, and emotional well-being of adults and children as well as the community. The Cooperative Extension Service (CES) has a long history of addressing marital quality in educational programs; therefore Extension is a natural partner in this current effort. This collection of papers, authored by members of the National Extension Relationship and Marriage Education Network and originally peer-reviewed and presented during the 2006 Family Life Electronic Seminar on Relationship and Marriage Enrichment Education (Futris 2006), presents examples of theoretically and empirically informed implications for relationship and marriage education.
