Objective: This study explored benefits of a relationship-focused intervention to enhance marriage communication designed for multicultural married couples and changes that occurred in the way the program’s participants communicated with one another. Method: The intervention program was implemented on six married multicultural couples (and six other couples as a control group), and their communication, conflict resolution, and adaptation before and after the intervention were examined. In addition, the researchers kept observation journals to understand the changes in the manner in which the married multicultural couples communicated with their spouse and examine their perception about participating in the program; further, we conducted post-program interviews with the participants after the completion of the program. Results: The results of this study are as follows: (1) the experiment group made more progress in improving couple communication, resolving marriage conflicts, and adapting as a married couple than the control group in a statistically significant manner in both preand post-program tests, and (2) the study confirmed through qualitative analysis that the program made positive contributions to improving the couples’ abilities to have conversations and resolve conflicts, as well as their intimacy. Conclusion: Based on these results, implications for further research and practices were discussed.
