The detection of malingering and deception with A short form of the MMPI-2 based on the L, F, and K scales

This project examined the use of a short inventory based on the validity subscales from the MMPI‐2. In Study 1, 69 subjects responded to the extracted L, F, and K items and to those items when embedded in the complete MMPI‐2. Correlations between administrations were equivalent to the original test‐retest reliabilities for these scales. In Study 2, 60 subjects responded to the short‐form with instructions to be honest, fake good, or fake bad. The correct classification rate was 77% using the standard MMPI‐2 rules of L > 70T for faking good and F > 70T for faking bad. Taken together, these findings suggest that the short‐form may be useful alone or when combined with other questionnaires to identify potential problems in self‐report.
