<unk>  is a form of behavioral addiction that can be described as the excessive or compulsive use of the<unk> , which persists despite serious negative consequences for personal, social, or occupational function. Another clear conceptualization is made by Block, who stated that "Conceptually, the diagnosis is a compulsive-impulsive spectrum disorder that involves online and/or offline<unk>  usage and consists of at least three subtypes: excessive gaming, sexual preoccupations, and e-mail/text messaging".<unk>  is not currently included in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as an official disorder. The concept of<unk>  is broadly divided into two types, namely offline<unk> , and online<unk> . Offline<unk>  is normally used when speaking about excessive gaming behavior, which can be practiced both offline and online. Online<unk> , also known as Internet addiction, gets more attention in general from scientific research than offline<unk> , mainly because most cases of<unk>  are related to the excessive use of the Internet. Experts on Internet addiction have described this syndrome as an individual working intensely on the Internet, prolonged use of the Internet, uncontrollable use of the Internet, unable to use the Internet in an efficient, timely matter, not being interested in the outside world, not spending time with people from the outside world, and an increase in their loneliness and dejection.
