Abstract

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. Emotional processing was assessed in three groups [1) SUD (without PTSD); 2) PTSD (without SUD); and 3) co-morbid SUD-PTSD] using the Emotional Processing Scale (EPS-25) and the International Affective Picture System (IAPS). Each of the three groups reported evidence of emotional processing dysfunction relative to the normal population. Within the SUD-PTSD group there was significant evidence that the additional impact of trauma increased emotional processing dysfunction but less evidence to suggest that substance use increased emotional processing dysfunction further. These findings call into question current United Kingdom guidelines for the treatment of co-morbid SUD-PTSD, which recommend that the drug or alcohol problem should be treated first.
