We investigated the effects of maternal parenting behaviors, children`s emotional regulation, and stress coping strategies on gender-specific children`s behavioral problems. The participants were 191, 4th and 5th graders and their mothers from four elementary schools in Seoul and Kyung-gi province. Collected data were analyzed by descriptive statistics and hierarchical regressions. The major findings were summarized as follows: (1) Active coping strategies explained boys` aggressive behaviors, (2) mother`s warm-encouragement parenting behaviors and active coping strategies explained boys` delinquent behaviors, (3) mother`s warm-encouragement parenting behaviors explained boys` withdrawn behaviors, and (4) mother`s mediation-supervision parenting behaviors and negative emotionality explained girls` aggressive behaviors. In conclusion, maternal parenting behaviors, children`s emotional regulation and stress coping strategies have gender-specific influence on children`s behavioral problems.
