Abstract

Using the MMPIand the IPI, the present study examined the differences in psychometric defensiveness between two groups of law enforcement applicants: applicants identified as being deceptive and a comparison group of candidates for whom no deception was indicated. Significant differences were found on the traditional validity (minimization) scales for both instruments as well as several supplemental scales and indexes from the MMPI. A new index (Es-K) from the MMPI showed a highly significant difference between groups and good classification accuracy. The results suggest that deceptive applicants show more defensiveness on psychometric testing and that test results may assist in raising the index of suspicion for detecting deception in law enforcement applicants.
