An important part of substance use treatment for many people is learning what triggers their substance use and urges, and how they can better manage those triggers. In this study, the investigators will generate a model for each individual that shows likely causal links between their substance use, urges, and comorbid symptoms (e.g., anxiety, depression, and PTSD), and the investigators will examine these models as a group to draw conclusions about common causes for substance use (and recovery) among Veterans with substance use disorders. The investigators will also test whether receiving a personal model and clinical feedback improves substance use disorder and comorbid symptom outcomes. Results will include both patient-reported and statistically-determined causes of substance use for individuals and groups, clinical impact of a personalized model and feedback session, and participant feedback about the relevance of this study and intervention.
