Academic researchers from universities in the United Kingdom, Germany, China and Australia have released a new psychological test that allows gamers to determine whether they suffer from "gaming disorder," an addiction first recognized as a form of mental illness by the World Health Organization last year.
WHO does not classify playing video games as a disorder, even in large amounts. Rather, like other types of addiction, the organization classifies gaming disorder as the playing of games to the detriment of the rest of a person's life, typically in a span extending for longer than a year.
