Executive function assessment requires reliable tools for providing targeted support in daily activities. This study evaluated the psychometric properties of the Japanese Behavior Rating Inventory of Executive Function-Adult Version (J-BRIEF-A), examining reliability, validity, and demographic variations in Japanese adults. Using cross-sectional design, data were collected from 1,378 adults aged 18-89 years (689 men) across Japan. Confirmatory factor analysis supported the nine subscales and three-factor model (CFI = .98; RMSEA = .094). High internal consistency and test-retest reliability were confirmed, with convergent validity established through significant correlations with the Dysexecutive Questionnaire (DEX). Graded response model analyses revealed excellent item discrimination parameters (range: 1.31-3.78) with appropriate difficulty thresholds across all subscales, indicating strong measurement precision. Full scalar invariance was established across gender, enabling meaningful comparisons between men and women. Across age groups, scalar invariance was confirmed for eight of nine subscales, with Plan/Organize showing inadequate fit requiring interpretive caution. Age-related patterns emerged, with younger participants scoring higher on individual items while overall executive function scores decreased with advancing age. Gender differences were observed across subscales. These findings confirm the reliability and validity of the J-BRIEF-A for assessing executive function in Japanese adults. Results have particular relevance given Japan's demanding work culture, where executive function challenges may be elevated among working-age populations requiring sustained attention and self-control. The comprehensively validated J-BRIEF-A provides clinicians and researchers with a culturally appropriate, psychometrically robust tool for identifying executive function difficulties and developing targeted interventions in Japanese clinical and community settings.
