Adaptation, Validity and Reliability of the Behavior Rating Inventory of Executive Function in 6-16 Children Year Old with Visual Impairment

The Behavior Rating Inventory of Executive Functions (BRIEF) had been used to examine executive functions in everyday behaviors. Despite the interference of visual impairment on executive functions, this scale has not been specifically studied and adapted for individuals with visual impairment. The aim of this study was to adapt and evaluate its reliability and validity on children with visual impairment in Isfahan. The present study is a descriptive study that was performed on 50 children (6-16-year-old) with visual impairment. The instrument used was BRIEF-parent form and items related to visual sense were removed. Through Smart PLS software, structural, convergent and divergent methods were used to check validity, and Cronbach's alpha coefficient and composite reliability were used for reliability. Confirmatory factor analysis for construct validity of 8 subscales of executive functions including inhibition, shifting, emotional control, initiation, working memory, planning/rganizing, organization of materials and monitoring was approved with appropriate factor loads (<0.4). Convergent (<0.4) and divergent validity was obtained to the appropriate extent. The results of Cronbach's alpha coefficients (< 0.7) and composite reliability (< 0.7) were also obtained. According to the findings, it is suggested that BRIEF in people with visual impairment has good reliability and validity and therefore it can be used to measure executive functions in children with visual impairment.
