LINEとTwitter（X）を介した攻撃行動を測定する尺度の作成

抄録

This research focuses on developing and validating self-report measures to assess aggressive behaviors via LINE and Twitter (X) platforms. The authors developed item pools for evaluating aggressive behaviors via LINE and Twitter based on existing scales or items assessing behaviors on the internet. Undergraduate students (N = 350) responded to these item pools, and measures of internet trolling, aggressive behaviors in real life, sadistic tendencies, and Big Five personality traits. Based on the results of exploratory factor analysis, the authors developed the Aggressive Behaviors via LINE Scale and the Aggressive Behaviors via Twitter Scale, each with a one-factor structure and high internal consistency. Further, correlations between the scales’ scores and validity measures indicated acceptable construct validity of the scales. These scales could be valuable tools for future research examining the determinants of aggressive behaviors via LINE and Twitter.
