The NEO PI-R, Inwald Personality Inventory, and MMPI-2 in the Prediction of Police Academy Performance: A Case for Incremental Validity

Abstract
The utility of personality inventories for predicting successful police officer performance is an important issue in the law enforcement employment selection process. The purpose of the present study is to evaluate the incremental validity of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the Inwald Personality Inventory (IPI), and the Revised NEO Personality Inventory (NEO PI-R) for predicting police academy performance of 79 recruits. Results indicate that each inventory contributes significantly to prediction of academic performance in the academy, while only the NEO PI-R predicts physical performance. The addition of the NEO PI-R to selection process that already incorporate the MMPI-2 and IPI may be useful for enhancing prediction of police officer performance.
