Book excerpt: State trooper job performance, as measured by supervisor ratings and patrol activity collected for a twelve-month period after all subject finished probation, was used to assess the predictive validity of the Big Five Personality Factors, as defined by various Minnesota Multiphasic Personality Inventory (MMPI) clinical scales, and Inwald Personality Inventory (IPI) scales. The MMPI and IPI were administered to a total 314 recruits from four resident State Police Basic Academy classes the first night at the academy. Inventory scores were not used for selection purposes. Data from 301 recruits were subjected to analysis. Confirmatory factor analysis was used to assess different Big Five-factor definitions, assembled using MMPI and IPI scales. Results show that the MMPI and IPI scales each provide a measure of one Big Five-factor personality domain. Neuroticism was measured by the MMPI, while Agreeableness was measured by the IPI. Neuroticism and Agreeableness were found to be parallel measures suggesting that a third personality domain, Hostility, was the primary determinant. Correcting for attenuation, subjects with elevated Hostility scores had lower job performance ratings (r = -.43), lower levels of patrol activity (r = -.18), lower Academy GPAs (r = -.30), and were more prone to leave the state police (r = -.24). It is suggested that Hostility may be a reliable and useful predictor for police officer selection.
