Does comorbid anxiety or depression affect clinical outcomes in patients with post-traumatic stress disorder and alcohol use disorders?

Post-traumatic stress disorder (PTSD) is commonly comorbid with other psychiatric disorders, including substance use disorders. In spite of this, pharmacologic treatment trials for PTSD often exclude individuals with significant psychiatric comorbidity. This study is a post hoc analysis of a 12-week double-blind placebo-controlled trial investigating sertraline in the treatment of patients with comorbid PTSD and an alcohol use disorder.
