Screening law enforcement cadets with the MMPI: An analysis of adverse impact

The MMPI was investigated for adverse impact against Blacks and Hispanics in a simulated employment selection procedure. Law enforcement academy cadets, who had received no preemployment psychological screening, took the MMPI on their first training day. The sample consisted of 184 males and 87 females with a mean age of 25.8 years. Twenty-five subjects were Black; 35 were Hispanic; and the remainder were white. Two clinical psychologists conducted a blind sort of the profiles, judging each as “acceptable” or “unacceptable” for employment as a law enforcement officer. Significant agreement was found for clinicians' judgments of suitablitity with no significant difference being found for either their overall acceptance rates or their acceptance rates for the different racial/ethnic groups. Also, there was no violation of the four-fifths rule. Analysis of variance found significant variability between groups on scales L and 6 (Pa) of the MMPI.
