Pre-Employment MMPI-2 Measures and Later Psychological Injury-Related Absenteeism among Police Officers

Abstract

Pre-employment screening to assess for psychological vulnerability is common in trauma-exposed occupations such as policing. However, the ability of such screening to predict those at increased risk of subsequent mental health problems has been questioned. The present study sought to investigate the ability of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) to predict absenteeism related to psychological injury in police officers. Pre-employment screening data from 1,399 sworn police officers was linked to organizational records. A total of 150 police officers who had taken at least 2 weeks’ sick leave with work-related mental health concerns were matched to 150 healthy controls. Conditional logistic regression was used to examine any association between MMPI-2 scales and psychological injury-related absenteeism. We found no evidence that elevations in the pre-employment MMPI-2 scores of police recruits were associated with an increased chance of future absenteeism as a result of psychological injury (P > 0.05). In addition, there was no evidence of an increased likelihood of psychological injury-related absenteeism among those with a higher number of positive pre-employment risk factors (P = 0.09). While the MMPI-2 may be able to predict different outcomes among police officers, it is important to note that based on these results, the MMPI-2, if used at pre-employment, is not able to predict later psychological injury-related absenteeism.
