MMPI profiles of problem peace officers

The Minnesota Multiphasic Personality Inventory (MMPI) profiles of officers who had been involved in serious disciplinary actions were compared with those of a matched group of officers who had not been involved in such actions. A multivariate analysis of variance (MANOVA) found the profiles of the two groups to be significantly different, with Scales F, 5, 6, and 9 significantly higher and Scale L significantly lower for the problem group. In addition, subjects in the problem group were twice as likely to have a high-point elevation T-score greater than or equal to 70 as their nonproblem counterparts. Overall, these results indicate that any degree of psychopathology, as reflected by MMPI profile elevations, increases the likelihood of serious job performance problems. In addition, a presentation of self as conventional and moderately defended is associated with a lesser likelihood of job difficulty, whereas characteristics such as hypersensitivity, impulsivity, and poor frustration tolerance contribute to significant job problems.
