Derivation of the Psychometric Properties of "Rapid Automatized Naming and Rapid Alternating Stimulus (RAN/RAS) Tests" in Arabic

Abstract

This study examined the psychometric proprieties of the Arabic version of the "Rapid Automatized Naming and Rapid Alternating Stimulus (RAN/RAS) Tests" for Jordanian students. A sample of 286 students (five to seventeen years old) was recruited from four public and four private schools in Jordan. Results indicated that the RAN/RAS Tests had high reliability and validity indicators. For example, RAN/RAS Tests had strong correlations with Letter Word Identification Test from the Arabic Woodcock Johnson Battery. In addition, there were significant relationships in all tests and the development of performance with the age or grade of the examinees. Furthermore, positive relationships among all RAN/RAS Tests confirm their consistency, strength, and reliability in measuring the required tasks. In general, results suggest that RAN/RAS Tests may be applicable to evaluating naming speed abilities and for distinguishing between students with and without reading disabilities in Arabic.
