The strategies used by 274 $4^{th}$ and $6^{th}$ graders for coping with stress were assessed by the Daily Hassles Coping Scale(Min & Yoo, 1998), and their behavior problems were assayed by their mothers with the Korean version of Achenbach's Child Behavior Check List(Oh, Lee, Hong, & Ha, 1997). Data were analyzed by descriptive statistics, 2-way ANOVA, and hierarchical regressions. Findings were that girls used more passive/avoidant coping strategies than boys; $6^{th}$ graders used more passive/avoidant coping strategies than $4^{th}$ graders; $6^{th}$ grade boys had more internalized behavior problems than $4^{th}$ grade boys; $4^{th}$ grade girls had more internalized behavior problems than $6^{th}$ grade girls; passive/avoidant strategies were positively related to internalized behavior; aggressive strategies were positively related to externalized behavior; strategies of seeking social support were negatively related to both internalized and externalized behavior problems.
