Since 1985, she has directed and consulted on adult prevalence surveys in seven countries and 25 states and provinces, in the United States, Canada, Australia, Britain, New Zealand, Norway, and Sweden. She has assessed the prevalence of gambling problems among vulnerable populations, including women, adolescents, Native Americans and older adults. 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.

In addition to assessing prevalence, Dr. Volberg has examined the social and economic impacts of gambling in several U.S. states as well as at the national level in Britain and the United States, working with international, multi-disciplinary teams. In Canada she is assessing the impacts of the legalization of online gambling in Ontario.

Dr. Volberg is a member of multi-disciplinary research teams in Australia, New Zealand, and Sweden conducting large-scale longitudinal panel studies to identify predictors of transitions into and out of gambling and problem gambling.

Dr. Volberg has completed literature reviews and translational reviews – using problem gambling research results to guide the development of prevention and treatment programs – for government agencies in Arizona, California, Britain and New Zealand. Dr. Volberg has testified before legislative bodies at the federal, state and provincial levels; presented papers at national and international conferences; and been an invited participant at several international forums on problem gambling.

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).
