This study sought to examine the reliability and validity of the Japanese version of the Behavior Rating Inventory of Executive Function (J-BRIEF). In this study, BRIEF was administered to evaluate executive function in everyday life in 91 subjects with autism spectrum disorder (ASD; ages 12–15; 72 boys) and 2,230 community samples (CS; ages 12–15; 1,083 boys). For this purpose, we applied categorical confirmatory factor analysis, which revealed that the scale was composed of two factors and eight subscales of the high test-retest stability. Reliability was confirmed using an external criterion (ADHD-Rating scale: ADHD-RS). Receiver operating characteristic analysis revealed an optimal cut-off of 118.5 (sensitivity = 0.811, specificity = 0.828). This study confirmed the reliability and the validity of J-BRIEF.
