The Japanese term “kireru” refers to an inability to control oneself and a tendency to exhibit violent rage. Kireru behaviors among young people have been increasing at home and at school; predicting these behaviors and solving the problem has become a social issue. The goal of this study was to develop a scale to predict kireru tendencies. A questionnaire consisting of 21 items measuring expressions of anger in three personal situations (friends, teachers, and family) was administered to 825 junior high school students (416 boys and 409 girls). Factor analysis revealed three dimensions: “extroversion of anger,” “introversion of anger,” and “control of anger.” Answers to the questionnaire revealed the following: (1) children expressed their anger toward family members most easily, whereas they suppressed anger toward teachers; (2) children tended to try harder to control their anger toward friends more than they did toward teachers or family; and (3) gender differences were observed in “extroversion of anger” (girls>boys) and “introversion of anger” (girls>boys).
