Psychometric Properties of the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF2) in Students aged 13 to 18 years

Performance-based measures have shown some limitations in the assessment of executive functions (EF) and rating scales have been proposed as an alternative. This study examined the psychometric properties of the Persian version of the Behavior Rating Inventory of Executive Function, Second Edition, BRIEF-2 parent - form in students aged 13 to 18 years. Participants were 300 students, 148-girl (49.3%) and 152-boy (51.7%) between 13 and 18 years old (M = 9.15; SD = 1.92). Samples were selected from regions (north, south, east, west and center) in Tehran city. The analysis of the internal structure using confirmatory factor analysis reveals that the model with three indexes (Behavioral, Emotional and Cognitive) and nine scales (Inhibit, Shift, Self-Monitor, Emotional Control, Initiate, Working Memory, Plan/Organize, Organization of Materials and Task-Monitor) showed good fit to the sample. The Cronbach's alpha values for the index scores ranged from.91 to.93, with alpha for the individual scales ranging from.87 to.92. Results showed that Persian version of the BRIEF-2 parent Form demonstrated high internal consistency and test–retest reliability. Convergent validity was obtained for BRI (AVE = 0.52), ERI (AVE = 0.54) and CRI (AVE = 0.58). In addition, composite reliability (CR) was reported for BRI (CR = 0.85), ERI (CR = 0.87) and CRI (CR = 0.83). According to the findings, it can be said that the Persian version of the BRIEF2 scale has the necessary convergent validity and composite reliability. The findings support the factorial validity of the BRIEF-2 scores, suggesting that it is an adequate instrument to evaluate executive functioning reported by parents and caregivers. According to the findings, it can be said that the Iranian version of the BRIEF-2 has good psychometric properties and can be a good tool for use in clinical and research situations.
