As the number of North Koreans defectors entering South Korea with their family members increases, it becomes more important to explore the family characteristics that facilitate their adjustment. The data used in the present study was collected from a survey of 195 North Korean defectors. The aim of this study was to investigates how the structural and relational aspects of family influence the socio-cultural adjustment of North Korean defectors. The structural characteristics of family life included whether or not the defectors exited with their family members, whether they were living with family members, and whether they were living with family members under the age of 18. The relational characteristics included family cohesion and adaptability. The study results showed that living with young family members was negatively associated with the social activity restriction problems commonly perceived by North Korean defectors. Family cohesion was also negatively associated with the social activity restriction problems and positively associated with the social isolation problems. The results of this study also showed that family adaptability was not significantly associated with any socio-cultural adjustment problems.
