Schinka, Kinder, and Kremer developed "validity" scales for the Revised NEO Personality Inventory (NEO PI-R; Costa & McCrae) to detect underreporting—the Positive Presentation Management (PPM) Scale and overreporting—the Negative Presentation Management (NPM) Scale. In this investigation, the clinical utility of these scales was examined using the established validity scales from the Minnesota Multiphasic Personality Inventory–2 (MMPI-2; Butcher et al.) as the referent. The sample was composed of 370 psychiatric patients who completed the NEO PI-R and the MMPI-2 as part of a routine evaluation. Results indicated that response distortion compromised the utility of the NEO PI-R domain scales. Moreover, the PPM and NPM scales and an NPM–PPM index significantly differentiated invalid under-and overreporting groups from a valid responding group. The PPM and NPM–PPM index were adequate in classifying under- and overreporters, respectively.

Key Words: NEO PI-R • response bias • validity scales • overreporting • underreporting • MMPI-2
