This study explored the parental belief types of mothers who had defected from North Korea and found out its relationship to the mother's child-rearing behaviors and socio-demographical variables and the child's age. 89 mothers who had defected from North Korea with the youngest child being under 20 years old, responded to the questionnaire. The data were statistically analyzed by cluster analysis, MANOVA, and X2- test. The results showed that the parental beliefs were clustered into 3 types:'high child- and parent-centered & low cultural transformation'(cluster 1)(37.08%), 'low child- and parent-centered & middle cultural transformation'(cluster 2)(46.03%), and 'high child- and parent-centered & high cultural transformation'(cluster 3)(16.85%). The differences among the clusters were found in the warmth․acceptance and rejection․restriction dimensions of the mother's child-rearing behaviors. The frequencies of each cluster were meaningfully different depending on the mother's age, educational level, length of residence in South Korea, and their child's age. Based on these findings, the implications and suggestions were discussed.
