PREP curricula are scientifically based.

Overview of PREP findings

The strategies of PREP are based on a body of research on marital and family health. The PREP Approach is based on over 40 years of research in the field of relationship health and success, with much of the specific research conducted at the University of Denver as well as other universities, with a great deal of the research being funded by federal agencies such as branches of the National Institutes of Health and the Administration for Children and Families. 

PREP works to regularly refine our strategies and materials based on ongoing research being conducted by various social scientists around the world. As research reveals more about relationships, PREP incorporates the latest most useful findings into its curricula.

While some of the values underlying strong and healthy relationships are timeless (e.g., respect, commitment, forgiveness), there is always more to learn about helping couples and individuals to become more resilient. As well as providing cutting edge knowledge, PREP also refines its educational strategies for teaching adult learners.
