The purpose of this study was to investigate the effect of perceived parental behavior and children’s coping behaviors with parent-related problems on parent-related stress. The subjects were 234 children composed of 115 3rd-graders and 119 6th-graders elected from three elementary schools in Seoul(121 males and 113 females). Statistical techniques were means, Percentages, Scheffe test, ANOVA and Multiple Regressions. The major findings of this study were as follows : 1) There was a significant difference in parent-related stress with respect to perceived parental behavior and coping behaviors of childrens such as passive, avoidant, and aggressive coping. Perceived parental behavior and aggressive coping behavior showed significant interaction effects. When children perceived parental behavior as being less suppotive and children more aggressively coped with parent-related problems, parent-rotated stress increased in level. 2) Among perceived parental behavior and pasive, avoid, aggressive coping behavior, perceived parental behavior and passive coping behavior were significant predictors of parent-related stress. Perceived parental behavior was much more predictor of parent-related stress than the passive coping behavior.
