The purpose of this study was to examine children's self-regulation and their problem behavior according to family interaction types. The subjects were 227 children and their mothers, and 14 teachers in Jeonbuk. To obtain family interaction types, self-questionnaires of FACES III are given to mothers. Also, self-questionnaires of children's self-regulation and problem behavior were given to teachers. The data were analyzed by computing t-test, ANOVA, Duncan post test, and multiple liner regression. The results were as follows. First, There was a difference in the children's self regulation and problem behavior, but not in family cohesion and adaptability, according to the children's sex, age, and family variables. Second, it was found that there was a difference in self-regulation and problem behavior according to family interaction types. It showed that self-regulation was higher and problem behavior was lower in the most 'enmeshed' families in cohesion and the most 'chaotic' families in adaptability. Third, considering the relative strength of each variable on children's problem behavior, it was shown that children's sex and age had the greatest influence on problem behavior, followed by self-regulation and family's cohesion. In conclusion, it is suggested that the efforts to improve family cohesion as a psychological environment should be made in order to increase the children's self regulation and to decrease the children's problem behavior.
