Twinning: Genetic and Environmental Influences on Gambling Habits in Minnesota Twins

by: NCRG staff | Jul 19, 2017

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.

What is the aim of this review?

NCRG-Funded Researchers in the News

by: NCRG staff | Mar 5, 2015

Research by two NCRG-funded investigators has recently received broad media coverage. Marc Potenza, MD, PhD, principal investigator of the Yale Center of Excellence in Gambling Research, was the senior author of an article published in the high-impact journal JAMA Psychiatry in February 2015. This twin study sheds new light on the relationship between gambling disorder and obsessive-compulsive behaviors. The study finds that individuals with severe obsessive-compulsive behaviors — or those who demonstrate specific forms of the behavior, such as fear of germs or desire for order in the environment — are also more likely to meet diagnostic criteria for gambling disorder.

New Research Explores the Genetic Links Between Disordered Gambling and Anxiety Disorders

by: NCRG staff | May 10, 2011

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).

New Research on the Impact of Having a Parent with Gambling Problems

by: NCRG staff | May 19, 2010

The following is an excerpt from the article, “All in the Family: New Research on the Impact of Having a Parent with Gambling Problems,” which was originally published in the spring 2010 edition of Responsible Gaming Quarterly.

Scientists and clinicians have long speculated that gambling disorders are more prevalent in families with a history of problem gambling behavior. The role that heredity plays in the development of a gambling disorder is important to research focused on the causes of the disorder and to assessment and treatment. Research has started to unravel the genetic versus environmental factors. A University of Minnesota study, “Characteristics of Pathological Gamblers with a Problem Gambling Parent,” recently published in The American Journal on Addiction, is the first attempt to determine whether having a problem gambling parent is associated with any unique clinical features in adults with pathological gambling (PG) (Schreiber, Odlaug, Kim, & Grant, 2009).
