This thesis examined the co-occurrence of trauma-related symptoms, PTSD, and SUD using Perceived Causal Relations scaling in an online community sample (n = 513) and in persons who were or had recently attended treatment for SUDs (n = 12). In both samples, participants perceived trauma-related reexperiencing and avoidance as significant causes of substance use partly dependent on the gender of the respondent, and men reported that dissociative experiences were more of an effect than a cause of their substance use.
