Abstract
The Psychopathic Deviate (Pd) Scale of the MMPI is often used by police departments in police selection. Unfortunately very little research data exists to substantiate the power of the Pd scale in police selection. In this study, self-ratings of satisfaction and performance of police officers were assessed using the Zytowski Personal Data Questionnaire. The Pd scale showed promise but the correlation between Pd and rated satisfaction was non-significant. When the scale was divided into Pd Obvious and Pd Subtle and correlated with satisfaction, a significant correlation between Pd Subtle and rated satisfaction emerged. When male officers alone were assessed, the results were even more significant. Included in the Pd Subtle are less transparent items which is a partial explanation of the results. For males, the Pd2 Authority Problems scale correlated significantly with both satisfaction and performance. The promise of the Pd Subtle as well as the Pd2 scales need to be investigated further.
