The purpose of this study was to measure the effectiveness of the Couple Communication Program(CCP) with Korean couples. The subjects were 25 married couples for pretest and posttest, and were 11 married couples for follow-up measure 6 weeks later. The couples were living in Seoul and Kyunggi-do province. The major results were as follows : CCP had a positive effect on marital communication behavior immediately after the program, but this effect partially diminished at follow-up. Especially the positive changes of wives` talking and couples` listening behavior were significantly decreased. CCP had also positive impacts on the improvement of couples` knowledge, attitude and thought, and on wives` self-esteem, husbands` depression and couples` marital relationship. These positive effects maintained at follow-up.
