The study investigated the psychometric properties of the Eysenck Personality Questionnaire-Revised (EPQ-R) Short Scale administered to two groups of Brunei trainee teachers of both genders taking psychology courses in English (117 students) and Malay (106 students). The extraversion scale had the most problematic items. Both administrations produced means and standard deviations comparable to the norms in the technical manual. All the scales, except P (psychoticism), had satisfactory levels of alpha reliability and validity (discriminant and construct) on both versions. In addition factor analysis correctly assigned some of the items to their respective scales on both versions. No statistically significant gender difference in performance on both scales was obtained. Findings suggest that the instrument was suitable for use with Brunei student teachers with tertiary-level education when technical terms were clarified and reasonable administration time was given.
