Abstract

Edwards Personal Preference Schedule (EPPS) is a measurement tool that is quite popular in psychology, which is used to see individual personalities through non-projection or inventory techniques. There are 15 needs (needs) in the EPPS, one of which is aggression. In this study, a descriptive analysis related to psychometric analysis using the Rasch model was carried out, including validity, reliability, item difficulty level, and Differential Item Functioning (DIF). The results of this study indicate that the items that measure the need for aggression have good validity and reliability coefficients. There is one item with a high difficulty level and one with a low difficulty level. Then two items are detected to be biased by gender.
