Introduction

Executive functions are a set of high-level cognitive abilities that are related to the educational problems of children.

Aim

This research aimed to investigate psychometric properties of the Persian version of the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF-2) and compare its indices among children with different types of specific learning disabilities (SLD).

Method

This study was descriptive psychometric and causal-comparative research. The statistical population consisted of the 6-12-year-old-girls and boys with SLD, Isfahan city, in 2020-2021. A total of 346 students were selected using a convenience sampling method. The achievement tests were then taken, and BRIEF-2 was completed by their parents. The data were analyzed using confirmatory factor analysis, differentiation analysis, Cronbach's alpha coefficient, split-half reliability coefficient, and multivariate analysis of variance (MANOVA) via SPSS.23.0 and AMOS.24.0 software.

Results

Confirmatory factor analysis results showed that this scale has acceptable fit indices values (RMSEA=0.072), and construct validity and discriminant validity are confirmed (P<0.001). In addition, the results of Cronbach's alpha coefficient (0.896) and split-half reliability coefficient (0.814) showed that the questionnaire has good reliability. Furthermore, MANOVA results indicated a significant difference between the indices of the BRIEF-2 and the type of learning disabilities (P<0.05).

Conclusion

The BRIEF-2 has good psychometric properties to evaluate the executive functions in 6-12-year-old children with SLD. Considering the significant relationship between the indices of the BRIEF-2 and the type of learning disabilities, the weakness in the indices of executive functions may be probably associated with children' learning problems.
