Application of Japanese Short Form Multidimensional School Anger Inventory to middle elementary school students

要旨

The Multidimensional School Anger Scale is a multidimensional evaluation scale for school anger, and its shortened Japanese version (JS-MSAI) has been developed in Japan. The target population is the 5th grade elementary school students to 2nd grade high school students. Considering that the number of violent acts in elementary schools is increasing year by year, it is necessary to understand the characteristics of feelings of anger in younger children as well. The purpose of this study is to examine the reliability and validity of a shortened version of the multidimensional scale of school anger in middle grades (3 and 4), and to examine the characteristics of their anger by comparing it with those in upper grades (5 and 6). A questionnaire survey was administered to 582 3rd and 4th graders and 525 5th and 6th graders in seven public elementary schools in Japan, and the reliability and validity of the JS-MSAI were examined. The analysis showed that the JS-MSAI has a certain degree of reliability and validity, although the alpha coefficient for “positive coping” is lower than the other subscales.
