disordered gambling

The Scientific Advisory Board of the National Center for Responsible Gaming (NCRG) is pleased to invite grant applications for research that explores the full spectrum of gambling behaviors from healthy to disordered. In addition, we are specifically interested in policy-relevant research. We invite applicants from a wide range of disciplines to apply, including economics, public health, cultural anthropology, neuroscience, psychology, psychiatry and public policy. This request for applications (RFA) is in effect for both Large Grant and Seed Grant applicants, Jan. 1, 2019 - Dec.

Although adolescents are particularly prone to environmental influences as they come into young adult age, few studies have looked at the effect that genetics versus environment has on gambling behaviors.  Serena King, PhD, a 2006 New Investigator grantee of the National Center for Responsible Gaming, built upon her prior work looking at personality, gender, and family history in the prediction of college gambling, with this 2017 longitudinal twin study.

After laying the foundation for his presentation by outlining the theoretical revolutions that have defined our understanding of gambling disorders, Dr. Howard Shaffer then proposed that the next revolution in understanding gambling disorders will come from the way online gambling behavior can now be studied. Until recently, information about people’s gambling behavior has come almost exclusively from self-report (asking a person questions about their past gambling behaviors). Self-report is considered to be acceptably accurate by the scientific community, but it relies on recollections of individuals that may be influenced by a variety of factors such as desire to please interviewers or to downplay losses. For years these problems with self-reported data have presented a challenge to researchers studying gambling disorders. However, Dr. Shaffer suggested that new innovations in research methods will decrease the role of self-report and allow researchers to look directly at the gambling behavior of online gamblers.

The people who work in casinos and other gaming venues are an important and under-researched group in the pathological gambling literature. Gaming employees constitute a unique group not only because they interact daily with customers in casinos, but because they are slightly more vulnerable to gambling disorders than the general population (Shaffer, Vander Bilt, & Hall, 1999). Because of these and other factors, most states and casino operators in the U.S. require gaming employees to go through training on the specifics of disordered gambling and responsible gaming.  However, there has been very little published research done on the effectiveness of employee training programs used by casinos. In fact, the first study of an employee training program by a U.S. research team was recently published in the Journal of Gambling Studies (Laplante, Gray, Labrie, Kleschinsky, & Shaffer, 2011). 

What affects the prevalence of gambling disorders in a given area? Is it access to gambling activities in general, access to a specific type of gambling activity, demographic characteristics, local norms, the presence of an underlying addictive syndrome, or some combination of these factors and others? These questions have been asked for many years and have inspired much debate in both political and academic circles. Studying a question like this requires competent and willing researchers, but also a favorable situation for research.

Unlike clinical trials, people cannot be randomly assigned to live within a certain distance of a casino, to prefer a particular gambling activity, or to have some particular demographic trait. This limitation can be overcome by taking advantage of “natural experiments,” times when some variable in a community changes and researchers can isolate the effect that variable has on the prevalence of gambling disorders in the community.

One such natural experiment will take place in Maryland over the next several years with the legalization of slot machines. The results of the first study measuring baseline disordered gambling in the state has just been released to the public, and further studies will be completed over the next several years to assess the effect (if any) of the addition of slot machines to existing gambling opportunities (Shinogle, Norris, et al., 2011).

Nathan Smith, program officer for the NCRG, sat down with Dr. Martens to discuss brief interventions for problem gambling and gives advice to campus health professionals on how to address gambling and gambling-related harms on campus.

To understand pathological gambling (PG) one must understand the disorders that co-occur with PG. A 2005 study of more than 43,000 representative Americans found that people with PG often have other mental health disorders at the same time (called comorbid disorders). Examples of these include alcohol use disorders (73 percent), drug use disorders (38 percent), mood disorders (49 percent), anxiety disorders (41 percent) and personality disorders (60 percent) (N. M. Petry, Stinson, & Grant, 2005). While it is reasonable to hypothesize that genetic and environmental factors are both responsible for these co-occurrences, more research is necessary to learn how the two variables work together. One study that addresses these questions was recently published in the Journal of Affective Disorders (Giddens, Xian, Scherrer, Eisen, & Potenza, 2011). The study used data from 7,869 male twins to examine the relationship between PG and two anxiety disorders, generalized anxiety disorder (GAD) and panic disorder (PD).     

The National Center for Responsible Gaming (NCRG) presented the first installment of the 2011 NCRG Webinar Series to more than 250 participants in March – one of the highest attended sessions for the NCRG. Led by Dr. Jon Grant, M.D., the webinar was titled “Gambling Disorders: What Addiction Professionals Need To Know” and cosponsored by NAADAC, the Association for Addiction Professionals.  Visit the NCRG website for an archived version of the presentation.

Have you ever been screened for a health problem? The answer is probably yes if you’ve ever been questioned by your doctor about symptoms or responded to a telephone survey about health. There are numerous screening instruments used by clinicians to determine if a client has a gambling problem, and some often appear in general population surveys to research the prevalence of the disorder. The Division of Addictions at Cambridge Health Alliance, a teaching affiliate of Harvard Medical School, recently released the Brief Biosocial Gambling Screen (BBGS) to help people decide on their own whether to seek a formal evaluation of their gambling behavior.  Development of the screen was funded by the NCRG.

Why do so many people relapse when they are trying to stop gambling? It has been estimated that 50 to 75 percent of gamblers resume gambling after attempting to quit (N. M. Petry et al., 2006), but what are the thoughts, feelings and situations that precede these events? Researchers who study alcohol and drug abuse – disorders with similarly high rates of relapse –  have developed a questionnaire designed to answer these questions for their audiences. A recent study published in the journal Experimental and Clinical Psychopharmacology attempts to validate this same type of questionnaire for people with gambling disorders (Nancy M Petry, Rash, & Blanco, 2010). The new study attempts to extend and validate Petry’s previous work adapting the Inventory of Drinking Situations for gambling situations (called the Inventory of Gambling Situations, IGS).
