Self-reported scales that adequately measure tonic irritability and provide international comparability are lacking in Japan. Therefore, the present study aimed to examine the reliability, validity, and cross-cultural adaptation of both self- and parent-reported versions of the Japanese version of the Affective Reactivity Index.
We used 2019 data from the Hirosaki City School Cohort Study, which is a part of the Assessment of Preschool to Adolescence-Longitudinal Epidemiological Study. To evaluate the construct validity of the Affective Reactivity Index, we examined the association between depressive symptoms and emotional and conduct problems. We applied item response theory to evaluate the psychometric properties of the Affective Reactivity Index and assess various latent traits.
Our findings confirmed the reliability and construct validity of both the self- and parent-reported versions of the Affective Reactivity Index ( = 0.86 and 0.82, respectively). The item response theory analysis confirmed the psychometric properties of these measures in a Japanese context.
This study comprehensively examined the reliability, validity, and cross-cultural adaptation of the Japanese version of the Affective Reactivity Index for both self- and parent-reports. These findings mark a crucial step in developing culturally adapted tools for assessing irritability in Japanese adolescents, contributing to both research and clinical settings.
在日本，缺乏能够充分测量紧张性易激惹且具有国际可比性的自我报告量表。因此，本研究旨在检验日本版情感反应指数自我报告版和家长报告版的信度、效度及跨文化适应性。
我们使用了弘前市学校队列研究2019年的数据，该研究是学龄前至青少年纵向流行病学研究评估的一部分。为了评估情感反应指数的结构效度，我们研究了抑郁症状与情绪和行为问题之间的关联。我们应用项目反应理论来评估情感反应指数的心理测量特性并评估各种潜在特质。
我们的研究结果证实了情感反应指数自我报告版和家长报告版的信度和结构效度（分别为0.86和0.82）。项目反应理论分析证实了这些测量方法在日本背景下的心理测量特性。
本研究全面检验了日本版情感反应指数自我报告版和家长报告版的信度、效度及跨文化适应性。这些发现标志着在开发适用于评估日本青少年易激惹性的文化适应性工具方面迈出了关键一步，对研究和临床环境均有帮助。
