Current opinion in psychiatry
-
The present review focuses on the co-occurrence of substance use disorder and post-traumatic stress disorder, with special attention to measurement and the role of violence as a contributor to the comorbidity. ⋯ Lack of consistency in terms of substance use classification and measurement of post-traumatic stress disorder across studies continues to hinder comparisons of rates of comorbid substance use disorder and post-traumatic stress disorder. More attention to the role of violence as a contributor to the comorbidity and its impact on treatment outcomes is warranted.
