Validation and normalization of the Japanese version of BRIEF among junior high school students

Abstract

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.
