The purpose of this study is to analyze four social interaction theories of a collaborative communication between a husband and a foreign immigrated wife. Marital conflict leads to positive and collaborative communication. The key factor of conflicts the foreign immigrant women experiences seems to be a absence of communication, misunderstanding of linguistic meanings, uncompromising position, and so on. In this study, we would like to examine how well collaborative communication in marriage life is formed based on the multicultural family couples' social interaction. Therefore, by conducting in-depth interviews with three couples, we enhanced the acceleration factor of collaborative communication in marital life, and analyze four theories of social interaction; conflict factor, competition, exchange, and cooperation. Immigrant woman and her spouse usually do not understand cultural differences and behaviors so that it brings marital conflict. (lnha University, Chung-Ang University)
