Development of the Japanese version of the Peer Conflict Scale

The present study sought to develop a Japanese version of the Peer Conflict Scale for high school students and to examine its reliability and validity. According to the results of the confirmatory factor analysis, the Japanese version of the Peer Conflict Scale, unlike the original version, had a three-factor structure, with sufficient internal consistency and strong measurement invariance across genders. Furthermore, this study examined the validity of the scale based on correlations with variables associated with the forms and functional aspects of aggressive behavior and anxiety. Findings showed that the Japanese version of the Peer Conflict Scale had good validity and may be administered to high school students.
