According to a research paper published by problem gambling expert Howard J. Shaffer of Harvard University and his colleague Ryan Martin, the incidence of problem gambling has decreased from 0.7% to 0.6%. His recently published research paper titled “Disordered Gambling: Etiology Trajectory and Clinical Considerations,” published in the Annual Review of Clinical Psychology, also concluded that online gambling does not foster problem gambling.
Shaffer suggests that online gambling does not constitute a greater risk of creating problem gamblers. Shaffer, in an interview with the Chicago Tribune, said, “People gambling on the Internet change from gambling more to less in weeks. The extent of Internet gambling for most is astoundingly moderate.”
Shaffer also said that current available evidence suggests that the rate of pathological gambling has remained relatively stable during the past 35 years despite an unprecedented increase in opportunities and access to gambling.
