成人期初期の日本人に対する実行機能行動評価尺度の信頼性・妥当性の検討

Executive functions are a broad category of cognitive processes that coordinate and control brain functions to achieve a goal. Several psychological symptoms, such as depression and attention-deficit/hyperactivity disorder (AD/HD), are known to be associated with executive dysfunctions. Thus, evaluating executive functions is becoming a core component of neuropsychological assessment, and rating scales for evaluating such functions in the everyday context are ecologically valid measures. The Behavior Rating Inventory of Executive Functioning (BRIEF) is a well-standardized and the most commonly used measure. This study explores the psychometric property of the adult version of the BRIEF (BRIEF-A) for a Japanese population. We conducted a questionnaire survey of 552 community-residing Japanese aged 20–29 years. The results of confirmatory factor analysis suggested a satisfactory fit for the proposed three-factor model, and internal consistency was sufficiently high. To investigate convergent and divergent validity, we examined correlations with two existing questionnaires and compared the scores between groups with more or less AD/HD-related symptoms. The findings indicate that BRIEF-A demonstrates sufficient reliability and validity in the Japanese sample during early adulthood.
