PTSD often coexists with other psychiatric disorders, including SUD (Simpson, Rise, Browne, Lehavot, & Kaysen, 2019). This comorbidity often complicates the management of these disorders especially as the concurrent onset of one increases the severity of the other (Stewart, Pihl, Conrod, & Dongier, 1998). To date, the few studies examining EMDR in comorbid SUD/PTSD have demonstrated its effectiveness on post-traumatic symptoms but more rarely on addictive symptoms (Tapia, 2019). This article defends the idea that Jeffrey Young’s schema therapy (Young, 1994) would be highly indicated to treat patients with this comorbidity. The aim of this article is therefore to demonstrate the interest of using an integrative therapeutic protocol that would combine schema therapy and EMDR tools among patients with comorbid SUD/PTSD. While waiting for the emergence of validated therapeutic recommendations for this population, we attempted to propose some clinical practice recommendations based on existing scientific data.
