An investigation of malingering posttraumatic stress disorder on the Personality Assessment Inventory.
J Pers Assess. 1998 Dec; 71(3):322-36.JP

Abstract

Utilizing the Personality Assessment Inventory (PAI; Morey, 1991), this study aimed to isolate a pattern of responding that is indicative of an attempt to malinger posttraumatic stress disorder (PTSD). The PAI profiles of 116 male participants were examined. Profiles of a group of 29 alcohol-abusing veterans with a primary Axis I (American Psychiatric Association, 1994) diagnosis of PTSD and a group of 30 alcohol-abusing veterans with no other diagnoses were compared to those of 27 undergraduate men instructed to feign PTSD. Control data were obtained from another group of 30 undergraduates. The student malingerers produced PAI profiles that were significantly different from the veterans with PTSD. Seven scales distinguished the malingerers from the veterans with an actual diagnosis of PTSD. Malingerers tended to overexaggerate pathology, inflating their scores on many clinical scales greater than the mean of the PTSD sample. Malingerers also scored higher on Morey's (1993) 8-item Malingering Index than either group of veterans and the controls. Only 2 scales reliably differentiated alcohol-abusing veterans with PTSD from those without the disorder. The implications of these findings in the diagnosis of PTSD are discussed.
