This study investigated whether a pain sample and pain simulators could be distinguished on the Pain Patient Profile (P3). Forty patients with a pain condition completed the P3 under normal instructions, while 20 students responded under instructions to feign a pain disorder but to attempt to avoid detection. The simulators did not differ on the P3 Validity Sea le corn pared with the pain group, but scored significantly higher than the pain group on the P3 clinical scales (Depression. Anxiety. Somatization). The simulators were more likely to obtain an abnormal score ( T score > 55) on all of the clinical scales. The Depression scale had highest positive and negative predictive power and correctly classified 80% of the participants. The P3 may be a useful screening tool for assessing those feigning pain but requires further research. (C) 2001 John Wiley & Sons, Inc.
