Abstract

The study aims to verify the psychometric properties of the Executive Functions Scale for students with intellectual disabilities. The initial version of the scale, before validation, consisted of (56) items distributed across five core dimensions: Emotional Control, Planning and Organization, Cognitive Flexibility, Working Memory, and Attention Control. The study sample comprised 156 students with intellectual disabilities from intellectual education schools in Cairo and Giza governorates in Egypt. The students' ages ranged from (9 to 11) years, with an average age of (10.06) years and a standard deviation of (0.747), The psychometric properties of the scale were verified as follows: the validity of the scale was assessed using criterion-related validity and factor validity (exploratory and confirmatory factor analysis), The reliability and internal consistency of the scale were also verified, The results indicated that the items of the scale loaded onto the five factors: Cognitive Flexibility (11 items), Working Memory (11 items), Attention Control (9 items), Planning and Organization (8 items), and Emotional Control (7 items). Consequently, the scale was revised to consist of 46 items. Confirmatory factor analysis was conducted, and the fit indices were within the acceptable range. The internal consistency of the scale was confirmed, with high and significant correlation coefficients at the (0.01) level, demonstrating the overall internal consistency of the scale. The reliability of the scale was further verified using Cronbach's alpha and split-half reliability, showing high reliability coefficients across all dimensions.
