Abstract |
Although evidence suggests that risk-taking among individuals with co-occurring posttraumatic stress disorder (PTSD) and substance use disorder (SUD) may be precipitated by trauma-related emotional distress, studies have yet to examine moderators of this effect. One moderator worth investigating is recurrent major depressive disorder (MDD), given its influence on emotional responding and subsequent behavior. This study examined the moderating role of recurrent MDD in the relation of PTSD to risk-taking propensity following neutral and trauma scripts among SUD patients. Participants were 193 patients with and without current PTSD and/or recurrent MDD in residential SUD treatment. Risk-taking propensity, as assessed through the Balloon Analogue Risk Task (BART), was evaluated following a neutral script and a personalized trauma script. A significant script by PTSD by recurrent MDD interaction was found. Participants with PTSD and recurrent MDD exhibited significantly lower risk-taking following the trauma script relative to participants with PTSD but no recurrent MDD. Moreover, participants with PTSD and recurrent MDD exhibited a significantly smaller increase in risk-taking following the trauma script (relative to the neutral script) than participants with PTSD but no recurrent MDD. Participants with PTSD and recurrent MDD did not differ significantly from participants without PTSD. Language: en |
