Annotation

This study examined whether there was any correlation between police candidates' k-scale elevations on the Minnesota Multiphasic Personality Inventory (MMPI) and subsequent job performance for 12 unselected police officers from a small suburban police force.

Abstract

All the active patrol officers who had been monitored on job performance using a standardized departmental procedure that focused on 10 job-performance areas. The most recent performance rating was compared with MMPI results obtained at the time of hiring. Two MMPI decision models (the Goldberg and Classification I methods) used in screening police applicants were also investigated. An unexpectedly high percentage of officers in the sample had high 'k's' on their MMPI's. The k and k addition MMPI scales had little correlation with job performance ratings; however, the decision rules correlated significantly with k added scales. There was no significant correlation between performance ratings and hiring decision rules. 2 data tables, appended study computations, and 5-item bibliography.
