Psychometric properties of the Behavior Rating Inventory of Executive Function, second edition (BRIEF2) self-report form in Iranian adolescents.

Background: This study investigated the psychometric properties of a Persian translation of the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF2) Self-Report form.

Method: Participants were 589 typically developing adolescents (336 girls and 253 boys), ages 11-18 years old (M = 15.16; SD = 2.04), in Iran. They completed the Persian version of the BRIEF2 Self-Report form and Teenage Executive Functioning Inventory (TEXI). The Persian translated BRIEF2 psychometric properties were examined via internal consistency, test-retest reliability, convergent validity via associations with TEXI scores, and internal structure using structural equation modeling (SEM) to evaluate fit of the three-factor structure from the original English version BRIEF2.

Results: Findings indicated the Persian version of BRIEF2 Self-Report form yielded scores with robust reliability, with internal consistency ranging from .87 to .93 and test-retest correlations ranging from .89 to .96, and adequate convergent validity, with correlations with the TEXI ranging from .48 to .79. SEM revealed that a three-factor solution was the best fitting model for the seven subscales of the Persian BRIEF2.

Conclusion: These findings support the clinical use of the Persian BRIEF2 in Iranian adolescents, including the interpretation of the BRIEF2 three-factor structure, as well as the multidimensional nature of executive functions.
