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…

Adolescent/Early Adult Antisocial Behavior and Drug Abuse

From Longitudinal Epidemiology comes evidence for a plausible pathway:

Deviant peer association

— Support for theory and development of

practical and useful interventions.

From Prevention: comes tests of the theory and tests of a plausible

intervention strategy:

Thus, all three branches of DESPR

contribute to a unified story about

pathways to drug use and how to

intervene in these pathways.

DESPR: 20062006 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.

Type 1 Type 2

Translational Research is NOT Unidirectional: There are Feedback Loops

• 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?

• Developmental differences must be considered in designing prevention strategies.

–Can frontal lobe functioning be strengthened?

Implications:

Translating Sensation Seeking Research into Clinical Study: Communications Research

Sensation-Seeking Targeting(Palmgreen et al., 2001)

• Used Activation model of information exposure to design messages for target audiences

• RESULTS: All 3 targeted television campaigns reversed upward trends in 30-day marijuana use among high SS
