Multidimensional Characteristics of Anger in Childhood and Adolescence

本研究编制了多维度学校愤怒量表（MSAI）的日文版。MSAI旨在从多维角度评估学校环境中的愤怒，包括愤怒体验（情感成分），愤世嫉俗的态度（认知成分），破坏性表达和积极应对（行为成分）。 探索性和验证性因素分析发现，四个因素的结构的J-MSAI是相同的原始MSAI。量表的可靠性得到了子量表内部一致性和重测稳定性的支持。量表的结构效度得到了跨仪器相关的支持。此外，初中生和高中生在愤世嫉俗态度上的得分高于小学生，而发展水平对愤怒体验和破坏性表达的影响不大。

This study developed the Japanese version of the Multidimensional School Anger Inventory (MSAI). The MSAI was devised to assess anger in the school context from a multidimensional perspective, which includes Anger Experience (affective component), Cynical Attitude (cognitive component), Destructive Expression and Positive Coping (behavioral component). Exploratory and confirmatory factor analysis identified that the four-factor structure of the J-MSAI was the same as for the original MSAI. The reliability of the scale was supported by internal consistency and test-retest stability for the subscales. The construct validity of the scale was supported by cross-instrument correlations. Furthermore, the results showed that junior high and high school students had higher scores for Cynical Attitude than elementary school students, whereas developmental level had little effect on Anger Experience and Destructive Expression.
