Students’ emotional intelligence represents an important variable that is connected to students’ academic achievementand life success. One main challenge when measuring students’ emotional intelligence is to have a valid and reliablemeasure that captures this emotional construct. The current study aims to investigate the psychometric properties of theArabic version of Alsmadoni emotional intelligence scale (AEIS-25) using item response theory (IRT) models. Thestudy was applied among 3030 students in grades 7-10 in Oman.Data model fit was examined through evaluating IRT assumptions (i.e. unidimensional assumption and localindependence assumption) and goodness of fit (i.e. items fit and persons fit). It was found that item parameters wereacceptable and satisfactory, which indicates the appropriateness of AEIS to examine emotional intelligence amongadolescents. Findings from exploratory factor analysis for 2924 students and for the remaining 24 items indicated thepresence of a 2-factor model since the third factor was loaded by only one item. AEIS was considered as a reliable andpotentially valid measure of trait emotional intelligence.
