The detection of feigned uncoached and coached posttraumatic stress disorder with the MMPI-2 in a sample of workplace accident victims.
In this study research participants completed the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) under standard instructions and then were asked to fake posttraumatic stress disorder (PTSD) when completing the MMPI-2 for a 2nd time in 1 of 4 conditions with different instructions on how to fake PTSD: (a) uncoached, (b) coached about PTSD symptom information, (c) coached about MMPI-2 validity scales, or (d) coached about both symptoms and validity scales. These MMPI-2 protocols were then compared with protocols of claimants with workplace accident-related PTSD. Participants given information about the validity scales were the most successful in avoiding detection as faking. The family of F scales (i.e., F, FB, FP), particularly FP, produced consistently high rates of positive and negative predictive power.
