Validation of an Arabic Version of the Gifted Rating Scales–School Form

Abstract

The purpose of this study was to explore the psychometric properties of an Arabic translation of the Gifted Rating Scales–School Form (GRS-S) on a national sample of 907 students from Cycle 1 (Grades 1 to 4) and Cycle 2 (Grades 5 to 10) from five governorates in Oman (Muscat, Dhofar, Al-Batinah North, Al-Sharqiyah South, and Al-Dhahira). The replicability of the GRS-S factor structure was examined using the confirmatory factor analysis (CFA). The CFA results supported the six-factor solution of the original scale. Also, Cronbach’s alpha reliability coefficients of the GRS-S subscales ranged from .91 to .96. The criterion-related validity for the GRS-S scores was supported as statistically significant correlations were found between the GRS-S subscales and the Gifted and Talented Rating Scales–Second edition (GATES-2), students’ academic achievement, and the scores of the Profile of Creative Abilities (PCA) rating scale. The metric invariance results revealed that the six-factor structure of GRS-S was equally applicable across gender and grade levels.
