In order to screen out potentially problematic individuals, psychological evaluations in preemployment screenings of police officer candidates are standard practice for most departments. However, the utility of these evaluations is compromised by underreporting response styles, which means evaluators are not aware of the need to evaluate substantive scale scores more cautiously. One potential problem is that it is generally assumed that underreporting captured by validity scale scores on one measure generalizes to other measures given near the same time. Previous research has supported this assumption, but not in a sample of police officer candidates. Thus, the goal of the current study is to investigate in a sample of police officer candidates if score suppression found across MMPI-2-RF Restructured Clinical scale scores generalizes to substantive scale scores on the CPI. To achieve this goal, police candidates will be placed in either a within-normal limits group (WNL) or a suspected underreporting group (UR), based on T-score cut offs as outlined by best practices in this setting. Mean differences between these groups on MMPI-2-RF Restructured Clinical scale scores and CPI substantive scale scores will be examined. I hypothesize that the UR group will score significantly lower than the WNL group on MMPI-2-RF and CPI substantive scale scores. If this hypothesis is supported, this study has implications for psychological assessment practices in the police preemployment screening process.
