The prevalence was found to be 5.06% among a high-school student population from Sri Lanka, suggesting an increasing trend in low- and middle-income countries as well. A longer time spent on video games predicts a tendency towards pathological gaming in the future. The studies, however, used various methodologies and definitions, which renders consensus difficult to achieve and may explain the wide range of prevalence. Research
Debates on the classification
A meta-analytic review of pathological gaming studies concluded that about 3% of gamers may experience some symptoms of pathological gaming. The report noted problems in the field with defining and measuring pathological gaming and concluded that pathological gaming behaviors were more likely the product of underlying mental health problems rather than the inverse.Barnett and Coulson expressed concern that much of the debate on the issue of addiction may be a knee jerk response stimulated by poor understanding of games and game players. Such issues may lead both society and scholars to exaggerate the prevalence and nature of problematic gaming, and over-focus on games specifically, while ignoring underlying mental health issues. However, Problem gamblers have a higher chance for getting mental illness as well.Other scholars have cautioned that comparing the symptoms of problematic gaming with problematic gambling is flawed, and that such comparisons may introduce research artifacts and artificially inflate prevalence estimates. For instance, Richard Wood has observed that behaviors which are problematic in regards to gambling may not be as problematic when put into the context of other behaviors that are rewarding such as gaming.
However, the clinical trials of potential treatments remain of low quality, except for cognitive-behavioral therapies, which shows efficacy to reduce gaming disorder and depressive symptoms but not total time spent. Although there is a scientific consensus that cognitive-behavioral therapy is preferable to pharmacological treatment, it remains difficult to make definitive statements about its benefits and efficiency due to methodological inconsistencies and lack of follow-up. Since efficacious treatments have not been well established, prevention of video gaming disorder is crucial. Some evidence suggest that up to 50% of people affected by the internet gaming disorder may recover naturally.Some countries, such as South Korea, China, the Netherlands, Canada, and the United States, have responded to the perceived threat of video game addiction by opening treatment centres. China
China was the first country to treat "internet addiction" clinically in 2008. The Chinese government operates several clinics to treat those who overuse online games, chatting and web surfing. Treatment for the patients, most of whom have been forced to attend by parents or government officials, includes various forms of pain including shock therapy. In August 2009, Deng Sanshan was reportedly beaten to death in a correctional facility for video game and Web addiction. Most of the addiction "boot camps" in China are actually extralegal militaristically managed centers, but have remained popular despite growing controversy over their practices.In 2019, China set up a curfew, banning minors from playing between certain hours.
