Using the MMPI to Assess Reported Cognitive Disturbances and Somatization as a Core Feature of Complex PTSD

Abstract

Minnesota Multiphasic Personality Inventory (MMPI) clinical scales as well as 4 sets of MMPI items known to be sensitive to neurological dysfunction (closed head injury, cerebrovascular disorder) were administered to survivors of childhood physical and/or sexual abuse and to non-abused adults. As predicted, relative to the comparison group of psychiatric patients, the abused participants scored significantly higher on Scale 8 (Schizophrenia) and on all 4 sets of items associated with neurological dysfunction. The results suggest that early abuse/trauma is associated with cognitive disturbances and somatization. Findings appear to support the conceptualization of these psychophysical experiences as a central part of what is often called “complex posttraumatic stress disorder.” Limitations and suggestions for further study are discussed.
