Rorschach Indicators of PTSD

Abstract

The complexity of posttraumatic stress disorder (PTSD) makes it difficult to assess and diagnose the syndrome. Most diagnostic tools are based on self-report questionnaires and are thus susceptible to both conscious and unconscious biases. Projective techniques, including the Rorschach inkblot test, might overcome these shortcomings. This retrospective study analyzed 187 Rorschach protocols, 4 or more years after the diagnosis (PTSD vs. non-PTSD) had been determined. The protocols were coded into the computer version of Exner’s Comprehensive System (RIAP5) (Exner, 2005) and then analyzed statistically, using linear regression. A 13-item model was found to significantly predict 36.6% of PTSD patients.
