The vast majority of those with opioid dependence do not receive treatment. This may be due to the limited availability of existing treatment programs and to a range of societal and individual-level barriers, including the stigma associated with identifying oneself as a substance user and difficulty attending a treatment program on a regular basis. Technology-based interventions have potential to help address these barriers and to expand access to evidence-based psychosocial treatment. Automated, computer-based interventions have found high user acceptance and utilization and shown promise in treating substance use disorders. The current study will evaluate a text-message-based psychosocial program called PIER1 (Preventing and Interrupting Early Relapse 1) when delivered to treatment-seeking opioid-dependent emergency department (ED) patients. PIER1 is an interactive program based on the Relapse Prevention Model. It is also informed by cognitive behavioral therapy and motivational interviewing.
