Reliability and validity studies of Behavioral Rating Inventory Of Executive Function (BRIEF) in a Turkish normative sample

Abstract

The aim of this study was to conduct reliability and validity studies of parent and teacher forms of BRIEF in a Turkish normative sample. Data were obtained from the parents and counselors of 312 healthy children and adolescents (213 girls, 99 boys) between the age of 5 to 18. Internal consistency study indicated that both parent and teacher forms of BRIEF make consistent assessments. Moderate levels of consistency and acceptable levels of item validity were also found between two forms. Construct validity study showed that items
in both forms are appertaining to common neuropsychological constructs. Factor analysis yielded two factor solution. Findings indicated that Turkish forms of BRIEF were reliable and valid instruments to measure different dimensions of executive functions.
