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

Abstract

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.
