The susceptibility of the Rorschach Inkblot Test to malingering of combat-related PTSD.
The ability of subjects to alter their responses on the Rorschach and self-report measures to fake the symptoms of combat-related Posttraumatic Stress Disorder (PTSD) was investigated. Subjects were 40 White male undergraduates, randomly assigned to either a control or role-informed malingerer group, and 20 White Vietnam veterans with PTSD. Subjects were administered the Rorschach, MMPI-2 validity scales, and Mississippi Scale for Combat-Related PTSD. Results indicated that malingerers were able to achieve scores similar to the PTSD patients on the Mississippi Scale and some Rorschach variables. However, they evidenced significant differences on the MMPI-2 validity scales and several important Rorschach variables. Malingerers typically gave responses that were overly dramatic and less complicated, less emotionally restrained, and indicated an exaggerated sense of impaired reality testing as compared to PTSD patients. Behavioral differences were also noted between the groups. Findings are discussed in the context of the study's limitations and the practical detection of malingered PTSD in clinical settings.
