This collection of papers offers theoretically and empirically informed recommendations for developing and implementing effective relationships and marriage education programs. Following an introductory chapter that discusses the role of the Cooperative Extension Service in addressing marital quality in educational programs, Chapter 2 explains the impact of couple functioning on individual, family, and community well-being, articulates the rationale for addressing couple relationships in family life education, and describes appropriate goals and approaches for relationships/marriage education. The next chapter presents a framework to develop and modify programs using existing research, as well as techniques to evaluate existing marriage education programs. Chapter 4 explains principles and strategies for designing relationships and marriage education programs and common challenges that may arise while planning and implementing these programs. The next series of chapters outline the needs of diverse audiences and programmatic strategies for serving them. Chapter 5 reviews aspects of adolescent relationships, proposes goals and objectives of relationships and marriage education targeting youth, and offers an example of an existing youth-focused relationships education curriculum. Chapter 6 summarizes the unique needs of stepcouples in marriage education, reviews appropriate theoretical approaches, offers specific content and learning objectives, and presents ideas to consider when working with stepcouples. Strategies for relationship and marriage education programs targeting low-resource and culturally diverse audiences are discussed in Chapter 7. The final chapter reviews the importance of building community collaborations, the advantages and challenges of doing so, and effective strategies for developing sustainable community collaborations that support healthy relationships and marriages.
