NIDA's Public Health Division aims to improve public health by promoting integrated approaches to understanding and addressing drug use-related problems. This includes epidemiological research, prevention strategies, and service delivery. Discover the link between childhood and adult antisocial behavior and drug use, as well as the benefits of early interventions and reducing aggressive behaviors. Learn about the cost-effectiveness of prevention programs and the importance of using scientific knowledge in practice.

DESPR Organization and Vision EPIDEMIOLOGY RESEARCH BRANCH PREVENTION RESEARCH BRANCH SERVICES RESEARCH BRANCH DESPR seeks to improve the nation’s 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.
First, a story exemplifying linkages of Epidemiology, Prevention and Services…
Epidemiological Finding: Childhood and Adult Antisocial Behavior Strongly Associated with Drug Use/Disorders Odds Ratios for Lifetime Antisocial Personality Disorder by Specific Drug Disorders, Reference group is persons without the drug disorder (NESARC Study, Compton 2004)
From Longitudinal Epidemiology comes evidence for a plausible pathway: Poor academic achievement Early Aggression Deviant peer association Adolescent/Early Adult Antisocial Behavior and Drug Abuse
From Prevention: comes tests of the theory and tests of a plausible intervention strategy: — Support for theory and development of practical and useful interventions.
Control:33%, reference • CC:25%, aRR 0.61 (0.37-1.00) • FSP: 25%, aRR 0.70 (0.50-0.98) ESTIMATED CUMULATIVE RISK CC=Classroom Centered FSP=Family-School Partnership 7 8 9 10 11 12 13 AGE OF FIRST TOBACCO USE From Prevention: Reducing Early Aggressive Behaviors Reduces Drug Use Modified from: Storr, et al., Drug and Alcohol Dependence, 66:51-60, 2002.
From Prevention: Enhancing Social Bonding Reduces Violence Hawkins, et al., Arch Pediatr Adolesc Med 1999
From Services: Early Interventions Can Be Cost-Effective Cost per Taxpayer Participant and Crime Victims Net Benefit Nurse Home Visiting Program $ 7,733 $15,981 Seattle Social Development Project $ 4,355 $14,169 Big Brothers/Sisters Mentoring $ 1,054 $ 4,524 Aos, et al., The Comparative Costs and Benefits of Programs to Reduce Crime, Washington State Institute for Public Policy, 2001
Ongoing Problem: To Reap Any Benefits From Scientific Knowledge It Needs To Be Used In Practice
From Services: Few Schools Use Effective Prevention Programs Ringwalt, et al. (2002), Prevention Science
Thus, all three branches of DESPR contribute to a unified story about pathways to drug use and how to intervene in these pathways.

Summary: Drug Abuse Research Needs a Systems Approach social DRUGS OF ABUSE behavior neuronal circuits protein expression genome
DESPR: 2006 Major Research Questions • What new theoretical approaches can inform our research? • What intrapersonal and environmental factors interact with each other and with genetic factors? • 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 FeedbackLoops 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?
