Disputed disorder: DSM[edit]
Internet addiction disorder is not listed in the latest DSM manual (DSM-5, 2013),[16] which is commonly used by psychiatrists. Gambling disorder is the only behavioural (non-substance related) addiction included in DSM-5. However internet gaming disorder is listed in an appendix as a disorder requiring further study.[16]
Jerald J. Block, M.D. has argued that internet addiction should be included as a disorder in the DSM-5. However, Block observed that diagnosis was complicated because 86% of study subjects showing symptoms also exhibited other diagnosable mental health disorders.[17]
