Interracial marriage has been growing in South Korea for the past two decades and formed a new family type, so called multicultural family. The present research seeks to understand lived experiences of the first generation of immigrant mothers in multicultural family by collecting survey data investigating mothers’ acculturation and coping strategies, psychological, emotional, and behavioral health outcomes. In addition, communication between mother and child, during the process of mothers’ acculturation into Korean culture, will be also explored from a mother’s perspective.
