Marriage and relationship education (MRE) and responsible fatherhood (RF) programs share the goal of improving the lives of children by strengthening the interpersonal skills of their parents. The origins of these program areas are distinct: MRE began primarily as a way to prepare couples for marriage whereas RF was originally designed to prepare unmarried fathers to reconnect with their children and families. However, a common purpose has emerged between the two fields. According to the U.S. Census, more than 2.5 million children are raised in families without their biological father. This statistic confirms the need for fatherhood-specific and relationship education programs. Such programs help families communicate effectively and understand the importance of father involvement and healthy co-parental relationships, regardless of relationship status. Responsible fatherhood and MRE programs both address the diverse needs of fathers and their families in effort to improve child well-being. Recent research indicates that these programs, when working collaboratively, can have a positive impact on fathers, children, and their families. This Tip Sheet highlights the commonalities and strengths of each program area and suggests strategies for practitioners interested in bridging the two fields. (Author abstract)
