The MMPI-2 and statisfactory police academy performance: Differences and correlations

The Minnesota Multiphasic Personality Inventory (MMPI) and its later revision (MMPI-2) have been the most frequently employed psychological instrument in the selection of law enforcement officers (Bartol, 1996). In this study, state police trooper cadets were given a broad number of measures including the MMPI-2 prior to academy admission. Their performance at the police academy was then analyzed and related to their performance on the MMPI-2. Using step-wise multiple linear regression. Hy3 and Sc4 scores produced significant negative correlation's with academy final grade point average. Student's unpaired 1-tests between successful and unsuccessful cadets revealed differences between the groups for several MMPI-2 subscales including, but not limited to, K, MA, and SI, Lastly, logistic regression revealed no single subscale, or combination of subscales, which significantly predicted classification of the cadets as either successful or unsuccessful based on their MMPI-2 scores alone. © 1999 Society for Police and Criminal Psychology.
