To evaluate and improve the effectiveness of programs for reducing drug abuse and related mental health as well as social problems. For many years, research staff at the IBR have given special attention to addictions and the evaluation of cognitive and behavioral interventions provided by community-based programs. Emphasis has been on the use of natural designs for studies in real-world settings and the use of advanced multivariate methodologies. Research interests in recent years have broadened to include related areas of significant public
concern—especially addiction treatments for criminal justice populations, and adolescents, as well as the spread of HIV and related infections among drug users. Other major areas of interest include organizational functioning and process research for improving field-based implementation strategies of science-based innovations.
