Recent work at Gemini Research has focused on improving methods for identifying problem gamblers in population research and clinical settings.

Gemini Research offers an unparalleled depth of experience as well as up-to-date knowledge of methodological and theoretical developments in the field of gambling research. Staff at Gemini Research have extensive experience with survey development, questionnaire design and sampling methods as well as statistical analysis and interpretation of survey results. Staff are intimately familiar with the instruments used to assess problem and pathological gambling in clinical settings as well as in surveys, with the procedures necessary to obtain the highest quality data for these surveys, and with the challenges sometimes associated with disseminating information from these studies to multiple audiences. Gemini Research houses one of the largest existing databases on gambling and problem gambling in the general population as well as an extensive library of published and unpublished research in this area.

Dr. Rachel A. Volberg

Dr. Rachel A. Volberg, President of Gemini Research, is widely regarded as the most experienced problem gambling epidemiologist in the world. Dr. Volberg has been involved in research on gambling and problem gambling since 1985. In North America, Dr. Volberg has directed baseline and replication prevalence surveys among adults in more than 25 states and provinces. In addition to sub-national studies in the United States, Canada and Australia, Dr. Volberg has directed or consulted on national problem gambling prevalence surveys in Britain, New Zealand, Norway, Sweden and the United States. Dr. Volberg has also directed problem gambling prevalence surveys among specialized populations, including adolescents, Native Americans and older adults.

In 1988, Dr. Volberg was the first investigator to receive funding from the (US) National Institutes of Health to study the prevalence of problem gambling in the general population. Since then, Dr. Volberg has been a prinicpal investigator, co-investigator or consultant on several NIH-funded studies of pathological gambling. Dr. Volberg is presently involved in projects funded by government agencies in Australia, Canada and Sweden to improve methods for assessing at-risk and problem gambling in clinical and community studies. She is also a consultant on longitudinal studies in Australia and Sweden, tracking individuals over time to determine the predictors of transitions into and out of problem gambling.

Alone and with colleagues, Dr. Volberg has completed numerous literature reviews on a range of topics related to gambling and problem gambling. Reviews on problem gambling measurement and problem gambling epidemiology as well as translational reviews--using problem gambling survey results to guide the development of prevention and treatment programs--have been completed for government agencies in Arizona, California, Britain and New Zealand. Other research activities at Gemini Research include secondary analysis of existing data sets to extract additional value.

Dr. Volberg established Gemini Research, Ltd. in 1992. In addition to her own business, Dr. Volberg holds professorial appointments at the University of Massachusetts, Amherst and the National Institute of Public Health and Mental Health Research at the Auckland University of Technology in New Zealand. She also holds an appointment as a Senior Research Scientist at the National Opinion Research Center at the University of Chicago (NORC).

Dr. Volberg sits on the Editorial Boards of the Journal of Gambling Studies, International Gambling Studies and the electronic Journal of Gambling Issues. She is a longtime member of the American Sociological Association and the National Council on Problem Gambling (NCPG).  From 2003 to 2006, Dr. Volberg served as President of this national advocacy organization.  She is a recipient of the NCPG Herman Goldman Foundation Award as well as the NCPG Distinguished Service Award for Research.

Dr. Volberg has published extensively; her works include numerous government reports, scholarly articles and book chapters as well as the book, When the Chips Are Down: Problem Gambling in America (New York, NY: Century Foundation, 2001). Dr. Volberg has presented papers at national and international conferences, testified before legislative bodies at the federal as well as state and provincial levels, and has been an invited participant at several international forums on problem gambling.
