CAT-PD and MMPI-3 Validity Scales Detect Simulated Overreporting and Underreporting.

Individuals can sway legal, medical, employment, or other decisions by dishonestly self-reporting on psychological tests. Accordingly, the Comprehensive Assessment of Traits relevant to Personality Disorder (CAT-PD) and the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) include validity scales to detect overreporting and underreporting. Although many studies have empirically tested the validity scales of the MMPI-2 and the MMPI-2-RF, fewer have done so with the updated MMPI-3, and none with the CAT-PD.
