Abstract
Posttraumatic stress disorder (PTSD) has received considerable attention in the field of trauma studies. Yet trauma survivors suffer from other psychological and physical symptoms including somatic complaints, or somatization. The extent to which the same emotional processes that predict PTSD are implicated in somatization has remained relatively unexamined. We contend that emotion regulation difficulties and alexithymia are also implicated in somatization, and the way in which these factors interact differentially place one at risk for somatization or PTSD. Regression analyses revealed that emotion regulation difficulties were more highly correlated with somatization for individuals who also reported greater alexithymia. This interaction was not observed for PTSD symptoms where both alexithymia and emotion regulation difficulties uniquely predicted PTSD symptoms.
