Substance use disorders (SUD) affect millions of Americans each year and present as one of the most pressing health policy issues of the modern era. While efficacious interventions and services are available for the treatment and long-term recovery support of SUDs, novel approaches are now available through the use of technology to further enhance accessibility and availability of such supports. These technologies, broadly considered digital recovery support services (D-RSS), are largely unstudied in the field, but present a potential opportunity to mitigate the societal and individual costs associated with SUD. The current dissertation examines D-RSS through a systematic review of the literature and two empirical investigations into the lifetime engagement of specific D-RSS among a representative sample of U.S. adults in recovery from alcohol use and other SUDs, and the characterization of the users and recovery-related outcomes of a D-RSS smartphone application. The health policy implications are then discussed related to the rationale for investing in D-RSS and the potential impact on substance use and recovery-related health policy in the United States.
