DESPR seeks to improve the nations public health by promoting integrated approaches to understand and address interactions between individuals and environments that contribute to the continuum of problems related to drug use. Our goal is to develop scientific knowledge with clear application to practice and public policy. PREVENTION RESEARCH BRANCH SERVICES RESEARCH BRANCH First, a story exemplifying linkages of Epidemiology, Prevention and Services Epidemiological Finding: Childhood and Adult Antisocial Behavior Strongly Associated with Drug Use/Disorders 20

Adolescent/Early Adult Antisocial Behavior and Drug Abuse Poor academic achievement Deviant peer association From Prevention: comes tests of the theory and tests of a plausible intervention strategy: Support for theory and development of practical and useful interventions. ESTIMATED CUMULATIVE RISK From Prevention: Reducing Early Aggressive Behaviors Reduces Drug Use Control: 33%, reference

neuronal circuits protein expression genome DESPR: 2006 Major Research Questions 1. What new theoretical approaches can inform our research? 2. What intrapersonal and environmental factors interact with each other and with genetic factors? 3. How can we blend science and services to measurably impact public health outcomes? Prevention 2006 Key Research Goal Develop and maximize use of high quality preventive interventions in real world settings through research on Individual factors Relationship of drug abuse prevention to HIV prevention
Environmental strategies Community-based participatory research What are we doing to develop and promote these themes? Workgroups, Meetings, Publications, etc. Translational Research is NOT Unidirectional: There are Feedback Loops Type 1 Type 2 Bi-Directional Influences Basic science laboratories prevention:
Sensation Seeking Neurobehavioral disinhibition Early-onset antisocial behavior Psychiatric co-morbidity Stress reactivity Prevention basic neuroscience laboratories: What are the biological mechanisms that explain the emergence of drug abuse during adolescence? What specific vulnerabilities are familial? What are the biological mediators of social interactions?
