David F. Duncan

David F. Duncan, Dr. P.H. was Born in Kansas City, Missouri on June 26, 1947. He is President of Duncan & Associates, a firm providing consultation on research design and data collection for behavioral and policy studies. He is also Clinical Associate Professor in the Department of Community Health at Brown University School of Medicine. His education included a B.A. in psychology from the University of Missouri at Kansas City, and graduate work in criminology at Sam Houston State University. He earned the degree of Doctor of Public Health from the University of Texas at Houston with an interdisciplinary concentration in behavioural sciences, epidemiology, biostatistics, and program and policy evaluation. He later earned a postdoctoral diploma in alcoholism early intervention and treatment effectiveness research from Brown University.

Contributions
Dr. Duncan is best known for his contributions in the field of drug abuse, which have often been highly controversial. In 1974, he and Edward Khantzian of Harvard Medical School, in separate publications, proposed what has come to be known as the self-medication hypothesis of addiction. Both authors proposed that addiction arose out of the use of drugs to medicate a preexisting disorder or problem. Dr. Duncan's version of the hypothesis is distinguished by its identification of addiction with negative reinforcement. Dr. Duncan argued that all of the characteristics commonly cited as typical of addiction, such as persistence in the face of negative consequences and high probability of relapse, are all common in any negatively reinforced behaviours.

Dr. Duncan was also one of the pioneeers of the strategy of harm reduction. He has argued that harm reduction approaches to addictions, HIV or other public health concerns are instances of the traditional public health practice of tertiary prevention -- prevention of deaths or disability that might otherwise occur due to a health problem. Dr. Duncan first applied this approach in his work with adolescent drug abusers in Houston, Texas in the early 1970s and soon afterward with heroin addicts. In 1983 he and Dr. Robert S. Gold published an argument for this approach, which they then called "cultivating drug use", using the word cultivating in its sense of the elimination of weeds and promotion of healthy growth.

Dr. Duncan has also been a pioneer in the development of computer assisted learning and particularly computer based health education. His leadership in this field began at the State University of New York at Brockport, where he collaborated with Robert S. Gold in developing the first course on computers in health education offered at any college. In 1980, he and Dr. Gold published two papers that spurred interest in the use of computers in health education. One of these papers was the first publication to suggest that microprocessors, as personal computers were then known, could be preferable to mainframe terminals for use in computer assisted learning. A few years later, Dr. Duncan and Dr. Gold, then at Southern Illinois University, taught the nation’s first college-level course on PC-based methods in education. Three years later, Dr. Duncan argued for the value of portable computers, which were just being introduced, for educational and data collection applications. He also pioneered the use of roleplaying games on the PC and internet for use in both health education and data collection.

Career
Dr. Duncan was a consultant to President Clinton's White House Office of National Drug Control Policy during his tenure as Senior Study Director of the Substance Abuse Research Group of the Westat corporation. In this position he also provided consultation to the National Institute on Drug Abuse, Center for Substance Abuse Treatment, Center for Substance Abuse Prevention, National Academy of Science, New York City Housing Authority, and SPSS, Inc.. He served from 1996 to 1998 as Senior Public Health Epidemiologist in the Director's Office of the Rhode Island Department of Health where he was coordinator of health policy and Project Director of the state's Unified Needs Assessment Program for Substance Abuse Prevention and Treatment.

His varied career has included positions in both juvenile and adult corrections, as a deputy sheriff and a private detective. He has directed a halfway house for drug abusers, a comprehensive drug abuse treatment center, and a private school for emotionally disturbed children. He served as a research associate to the working group on substance abuse treatment for the President's Task Force on National Health Care Reform chaired by First Lady Hillary Clinton in 1993. He has held academic appointments as Associate Professor of Health Science at the State University of New York at Brockport, Professor of Health Education at Southern Illinois University, Professor of Biology at the Community College of Rhode Island, Professor of Health and Environmental Research at the University of Cologne in Germany, and Associate Professor of Community Health at Brown University. He has been a visiting lecturer at the University of Rochester, New York State School of Psychiatry, Columbia University's Teachers College and School of Public Health, New England Gerontology Academy, Trinity College (Dublin), Oxford University, German Academy of Public Health, University of Wurzburg, and Universidad Complutense de Madrid.

He is chair of the Council on Illicit Drugs and a member of the Board of Directors of the National Association for Public Health Policy. He chairs the Advisory Committee for the M.P.H. Program at Fort Valley State University. He is a member of the Corporation (governing body) of Butler Hospital, a psychiatric hospital in Providence, Rhode Island, and of the Board of Directors of the Bowling Green-Warren County Primary Care Center in Bowling Green, Kentucky. He is a past chairman of the Mental Health Section of the American Public Health Association, and has served on A.P.H.A.'s committees on Program, Membership, and Continuing Education.
