Emotional Processing in Individuals with Substance Use Disorder and Posttraumatic Stress Disorder.

Previous research has shown that individuals with substance use disorder (SUD) and posttraumatic stress disorder (PTSD) have emotional processing difficulties. However, no studies have specifically investigated the role of emotional processing in those with co-morbid SUD-PTSD. This study investigated whether there are more emotional processing abnormalities among patients with SUD-PTSD, than those with either a single diagnosis of PTSD or SUD.
