An Overview of Internet Addiction By Elizabeth Hartney, PhD - Reviewed by a board-certified physician. Updated July 20, 2016 Internet addiction is a behavioral addiction in which a person becomes dependent on use of the Internet, or other online devices, as a maladaptive way of coping with life's stresses. Internet addiction is becoming widely recognized and acknowledged, particularly in countries where it is affecting large numbers of people, such as South Korea, where it has been declared a national health problem. Much of the current research on the subject of Internet addiction has been carried out in Asia. It is also a growing concern in developed nations in North America and Europe.Top 5 Things to Know About Internet AddictionInternet addiction is not yet an officially recognized mental disorder. Researchers have formulated diagnostic criteria for Internet addiction, but it is not included in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). However, Internet gaming disorder is included as a condition for further study, and Internet addiction is developing as a specialist area. List Five Types of Internet Abuse Used to Cyberbully Article What Is Shopping Addiction? At least three subtypes of Internet addiction have been identified: video game addiction, cybersex or online sex addiction, and online gambling addiction.Increasingly, addiction to mobile devices, such as cellphones and smartphones, and addiction to social networking sites, such as Facebook, are being investigated. There may be overlaps between each of these sub-types. For example, online gambling involves online games, and online games may have elements of pornography.Sexting, or sending sexually explicit texts, have landed many people in trouble. Some have been teens, who have found themselves in hot water with child pornography charges if they are underage. Treatment for Internet addiction is available, but only a few specialized Internet addiction services exist. However, a psychologist with knowledge of addiction treatment will probably be able to help.Symptoms of Internet AddictionAs Internet addiction is not formally recognized as an addictive disorder, it may be difficult to get a diagnosis. However, several leading experts in the field of behavioral addiction have contributed to the current knowledge of symptoms of Internet addiction. All types of Internet addiction contain the following four components:1. Excessive Use of the InternetDespite the agreement that excessive Internet use is a key symptom, no one seems able to define exactly how much computer time counts as excessive. While guidelines suggest no more than two hours of screen time per day, this is unrealistic for people who use computers for work or study. Some authors add the caveat “for non-essential use,” but for an Internet addict, all computer use can feel essential.

WithdrawalAlthough originally understood to be the basis of physical dependence on alcohol or drugs, withdrawal symptoms are now being recognized in behavioral addictions, including Internet addiction. Common Internet withdrawal symptoms include anger, tension, and depression when Internet access is not available. These symptoms may be perceived as boredom, joylessness, moodiness, nervousness, and irritability when you can’t go on the computer.3. ToleranceTolerance is another hallmark of alcohol and drug addiction and seems to be applicable to Internet addiction as well. This can be understood as wanting—and from the user's point of view, needing—more and more computer-related stimulation. It can take several forms.You might just want more time on the computer, so it gradually takes over everything you do. Or you might want more technology—bigger, better or the latest software, hardware or gadgets. Either way, the quest for more is a predominant theme in your thought processes and planning.4. Negative RepercussionsIf Internet addiction caused no harm, there would be no problem. But when excessive computer use becomes addictive, something starts to suffer. You may not have any real personal relationships, or the ones you do have may be neglected or suffer arguments over your Internet use. Online affairs can develop quickly and easily, sometimes without the person even believing online infidelity is cheating on their partner.You may see your grades and other achievements suffer from so much of your attention being devoted to Internet use. You may also have little energy for anything other than computer use—Internet addicts are often exhausted from staying up too late on the computer and becoming sleep deprived.

Finances can also suffer, particularly if your weakness is for online gambling, online shopping or cybersex.Internet Addiction in KidsInternet addiction is particularly concerning for kids and teens. Children lack the knowledge and awareness to properly manage their own computer use, and have no idea about the potential harms that the Internet can open them up to. The majority of kids have access to a computer, and it has become commonplace for kids and teens to carry cellphones.While this may reassure parents that they can have two-way contact with their child in an emergency, there are very real risks that this constant access to the Internet can expose them to. Children have become increasingly exposed to lengthy periods of time connected to the Internet, disconnecting them from the world around them. When online, they have increased risk of involvement in cyberbullying, both as a victim, and as a perpetrator. There is also increased risk that they will use their cellphone for cybersex, particularly through sexting, and accessing apps which could potentially increase the risk of sex addiction and online sexual harms, such as Tinder.Read: Cybersex Safety RisksIn addition, kids are increasingly exposed to peer pressure through their cellphones and may spend extended periods of time playing online games, making them vulnerable to developing video game addiction. This can be disruptive to the development of healthy social relationships and can lead to isolation and victimization. For these reasons, children and teens are advised to have no more than two hours of screen time per day.Next Steps to ConsiderIf you recognize the symptoms of Internet addiction in yourself or someone in your care, talk to your doctor about getting help. As well as being able to provide referrals to Internet addiction clinics, psychologists, and other therapists, your doctor can prescribe medications or therapy to treat an underlying problem if you have one, such as depression or social anxiety disorder.Internet addiction can also overlap with other behavioral addictions, such as work addiction, television addiction, and smartphone addiction.A Word From VerywellInternet addiction can have devastating effects on individuals, families, and particularly growing children and teens. Getting help may be challenging but can make a huge difference to your quality of life.Sources:American Psychiatric Association. Diagnostic and Statistical Manual of Mental Disorders, DSM-5.
