This study examined longitudinally the relationships between school and home stressors (school work,friends,teachers,and parents) and stress responses (irritated-angry emotion,depressive-anxious emotion,cognition-thought of helplessness,and physical response). The participants were 124 sixth-year elementary school students,288 first-year junior high school students,a nd 242 first-year high school students. The surveys were carried out at the beginning,the middle,and the end of a school year. School work stressor was significantly and consistently correlated with cognition-thought of helplessness. Teacher stressor was also significantly and consistently related to irritated-angry emotion. Moreover,friend stressor was significantly and consistently correlated with depressive-anxious emotion.
