This study investigated the psychometric properties of a Persian translation of the Behavior Rating Inventory of Executive Function(BRIEF2) in 253 children with ADHD in Iran (137 boys, 116 girls)ages 8 to 12 years old (M = 10.04; SD = 1.42). The parents of the children completed the Persian BRIEF2 and the Childhood Executive Functioning Inventory (CHEXI). The findings indicated that the Persian version of BRIEF2 had good reliability (internal and test-retest) and satisfactory to good validity (convergent and construct). With respect to its construct validity, confirmatory factor analysis revealed that a three-factor solution was the best model fit for the nine subscales of the BRIEF2, which supports the valid interpretation of the three BRIEF2 indexes in the Persian BRIEF2. These findings support the clinical relevance of the Persian BRIEF in Iranian children with ADHD, as well as the multidimensional nature of executive functions.
