Standardization of Modified Image for/about Personality Eysenck Scales Using Item Response Theory on Taiz University Students

Abstract

#The study aimed to obtain a modified image of Eysenk personal scale, and rearrange its four factors (Neuroticism, Psychoticism, Lying and Extraversion) separately, and then finding psychometric properties and Percentile and T standards. The study used the Eysenk scale of personality, which standardized by Abdul Khaliq (1991) on the Egyptian Environment and consisted of 91 items. The test was conducted on a sample of (510) male and female students from Taiz University using "SPSS" program version (13) and Winsteps Version(2.88) program for statistical treatment in accordance with Rasch Model. The study concluded (51) items to the four factors and showed the necessity of omitting one item of Neuroticism factor because it was not fitting the Rasch model. The rest items that were left were (50) items. Moreover, the study showed high correlation coefficients for the four factors ((Neuroticism, Psychoticism, Lying and Extraversion), While the correlation coefficient of Psychoticism factor was very low. Finally the researcher designed the Percentile and T standards for the rest three factors (Neuroticism, Lying and Extraversion) for male and female students.
