title: Are Internet use and video-game-playing addictive behaviors? Biological, clinical and public health implications for youths and adults.
abstract: Internet use and video-game playing are experiencing rapid growth among both youth and adult populations. Research suggests that a minority of users experience symptoms traditionally associated with substance-related addictions. Mental health professionals, policy makers and the general public continue to debate the issue of Internet addiction (IA) and problematic video-game playing (PVG). This review identifies existing studies into the clinical and biological characteristics of these disorders that may help guide decisions as to whether or not IA and PVG should be grouped together with substance use disorders (SUDs).
