This paper reports a randomized controlled trial to investigate the effects of a Marital-relationship enhancement program(MREP) for marital couples.

Volunteer couples from several well-being centers in Seoul were randomly assigned either to a treatment group (n=36), participating in a MREP based on Gottman's “sound marital house” theory, or to a control group (n=35) receiving no treatment. The content of the MREP was provided to the control group after the research was completed. Data was collected from December 2003 to May 2004 using modified versions of the inventories developed by Gottman on marital satisfaction, positive affect, conflict regulation, and communication barriers.

Participants in the experimental group showed significant improvements in marital satisfaction, positive affects, conflict regulation, and communication-barrier scores compared to the control group.

The present program for marital-relationship enhancement is helpful in enhancing marital relationships and regulating conflict between marital couples and, ultimately, may be useful to prevent divorce.
