Relationship skills and strategies began to be taught in earnest in the early 1970s. By then, researchers had compiled enough concrete scientific evidence that couples could learn ways in which to safeguard their relationships and improve their mutual understanding and intimacy levels. Up until that point, the primary resource for couples was marriage therapy. Drs. Howard Markman and Scott Stanley, two of the primary founders of PREP, Inc., have conducted numerous research studies to determine what skills and strategies most benefit participants who seek to improve their relationships.

The articles below fall into the Basic Science Research category. These articles focus on the individual variables that impact relationship success; such as communication strategies, oxytocin levels, or co-habitation prior to marriage. This research is highly respected in the field of relationship education, and it is not uncommon to see the findings in these articles and the names Markman and Stanley cited in even our competitors' curricula.
