This study explored the moderating effects of self control and social support in terms of the relationship between stress and problem behaviors of children of divorced single parent families according to gender. A questionnaire was administered to elementary school-aged children (grades 3-6). 266 children from divorced single parent families were surveyed. The major findings were as follows : first, self control had a moderating role to play in the relationship between stress and problem behaviors for girls. Second, social support also had a moderating effect in the relationship between stress and problem behaviors for boys. Third, the variables having a moderating effect in the relationship between stress and problem behaviors of children also differed according to gender. Therefore differences in gender should be considered when seeking moderating the relationship between stress and problem behaviors of children.
