Identifying Internet addiction disorder is empirically difficult. Various screening instruments have been employed to detect Internet addiction disorder.
Initial indicators A study conducted by Lori C. Soule, L. Wayne Shell, and Betty A. Kleen (2003) titled "Exploring Internet Addiction: Demographic Characteristics and Stereotypes of Heavy Internet Users" found that heavy internet users were more likely to be male and younger than non-heavy users. The study also found that heavy internet users were more likely to use the internet for gaming and entertainment purposes, rather than for work or
education. It also went on further to suggest that heavy internet use may be related to certain personality traits, such as sensation-seeking and
impulsivity, and highlight the need for further research to better understand the
psychological factors that contribute to internet addiction. The study also highlights the need for interventions that target specific groups, such as young males who are heavy internet users, and that address the underlying factors that contribute to problematic internet use behaviors. A few obstacles are present in creating an applicable diagnostic method for Internet addiction disorder. •
Wide and extensive use of the Internet: Diagnosing Internet addiction is often more complex than substance addiction as internet use has largely evolved into being an integral or necessary part of human lives. The addictive or problematic use of the internet is thus easily masked or justified. Also, the Internet is largely a pro-social, interactive, and information-driven medium, while other established addiction behaviors such as gambling are often seen as a single, antisocial behavior that has very little socially redeeming value. Many so-called Internet addicts do not experience the same damage to health and relationships that are common to established addictions. •
High comorbidity: Internet addiction is often accompanied by other
psychiatric disorders such as personality disorder and intellectual disability. It is found that Internet addiction is accompanied by another
DSM-IV diagnosis 86% of the time. In one study conducted in South Korea, 30% of the identified Internet addicts have accompanying symptoms such as anxiety or depression and another 30% have a second disorder such as
attention deficit hyperactivity disorder (ADHD). Another study in South Korea found an average of 1.5 other diagnoses among adolescent internet addicts. It generally remains unclear from existing literature whether other psychiatric disorders is the cause or manifest of Internet addiction. Despite the advocacy of categorizing Internet addiction as an established illness, neither
DSM-IV (1995) nor
DSM-5 (2013) considers Internet addiction as a mental disorder. A subcategory of IAD,
Internet gaming disorder is listed in DSM-5 as a condition that requires more research in order to be considered as a full disorder in May 2013. The
WHO's
International Classification of Diseases (ICD-11) recognizes
gaming disorder as an illness category.
Screening instruments DSM-based instruments Most of the criteria utilized by research are adaptations of listed mental disorders (e.g., pathological gambling) in the
Diagnostic and Statistical Manual of Mental Disorders (DSM) handbook. • Preoccupation with the Internet; • A need for increased time spent online to achieve the same amount of satisfaction; • Repeated efforts to curtail Internet use; • Irritability, depression, or mood liability when Internet use is limited; • Staying online longer than anticipated; • Putting a job or relationship in jeopardy to use the Internet; • Lying to others about how much time is spent online; and • Using the Internet as a means of regulating mood. While Young's YDQ assessment for IA has the advantage of simplicity and ease of use, Keith W. Beard and Eve M. Wolf in 2001 further asserted that all of the first five and at least one of the final three criteria (in the order above) be met to delineate Internet addiction in order for a more appropriate and objective assessment. Young further extended her eight-question YDQ assessment to the now most widely used Internet Addiction Test (IAT), which consists of 20 items with each on a five-point
Likert scale. Questions included on the IAT expand upon Young's earlier eight-question assessment in greater detail and include questions such as "Do you become defensive or secretive when anyone asks you what you do online?" and "Do you find yourself anticipating when you go online again?". A complete list of questions can be found in Dr. Kimberly S. Young's 1998 book
Caught in the Net: How to Recognize the Signs of Internet Addiction and A Winning Strategy for Recovery and Laura Widyanto and Mary McMurran's 2004 article titled
The Psychometric Properties of the Internet Addiction Test. The Test score ranges from 20 to 100 and a higher value indicates a more problematic use of the Internet: • 20–39 = average Internet users, • 40–69 = potentially problematic Internet users, and • 70–100 = problematic Internet users. Over time, a considerable number of screening instruments have been developed to diagnose Internet addiction, including the Internet Addiction Test (IAT), the Chinese Internet Addiction Inventory (CIAI), the Korean Internet Addiction Self-Assessment Scale (KS Scale), the Compulsive Internet Use Scale (CIUS), the Generalized Problematic Internet Use Scale (GPIUS), the Internet Consequences Scale (ICONS), and the Problematic Internet Use Scale (PIUS). Among others, the Internet Addiction Test (IAT) by Young (1998) exhibits good internal reliability and validity and has been used and validated worldwide as a screening instrument. •
Excessive use: compulsive Internet use and excessive online time-use; •
Withdrawal symptoms: withdrawal symptoms including feelings such as depression and anger, given restricted Internet use; •
Tolerance: the need for better equipment, increased internet use, and more applications/software; •
Negative repercussions: Internet use caused negative consequences in various aspects, including problematic performance in social, academic, or work domains. More recently, researchers
Mark D. Griffiths in 2000 and Jason C. Northrup and colleagues in 2015 claim that Internet per se is simply the medium and that the people are in effect addicted to processes facilitated by the Internet. Based on Young's Internet Addiction Test (IAT), As a consequence of studies being conducted in divergent contexts, studies constantly modify scales for their own purposes, thereby imposing a further challenge to the standardization in assessing Internet addiction disorder. The extent to which Internet use can cause negative health consequences is, however, not clear from such a measure.
Neuroimaging studies revealed that IAD contributes to structural and functional abnormalities in the human brain, similar to other behavioral and substance additions. Therefore, objective non-invasive neuroimaging can contribute to the preliminary diagnosis and treatment of IAD.
Electroencephalography-based diagnosis Using
electroencephalography (EEG) readings allows identifying abnormalities in the electrical activity of the human brain caused by IAD. Studies revealed that individuals with IAD predominantly demonstrate increased activity in the
theta and
gamma band and decreased
delta,
alpha, and
beta activity. Following these findings, studies identified a correlation between the differences in the EEG readings and the severity of IAD, as well as the extent of
impulsivity and inattention. A 1999 study asserts that Internet addiction is a broad term which can be decomposed into several subtypes of behavior and impulse control problems, namely, •
Cybersexual addiction: compulsive use of adult websites for cybersex and cyberporn (see
Internet sex addiction) •
Cyber-relationship addiction: Over-involvement in online relationships •
Net compulsions: Obsessive
online gambling, shopping or
day-trading •
Information overload: Compulsive web surfing or database searches •
Computer addiction: Obsessive computer game playing (see
Video game addiction) For a more detailed description of related disorders please refer to the related disorders section above.
Public concern Internet addiction has raised great public concern in Asia and some countries consider Internet addiction as one of the major issues that threatens public health, in particular among adolescents. Internet addiction has been seen as a growing concern among adolescents, with many spending a significant amount of time online and exhibiting problematic use behaviors such as compulsive internet use and withdrawal symptoms when offline. Certain demographic factors, such as gender and socioeconomic status, may be associated with higher rates of internet addiction. Various factors may contribute to the development of Internet addiction, including individual factors such as depression, anxiety, and poor self-regulation, as well as environmental factors such as
parental monitoring and peer influence. Poor academic performance, disrupted sleep patterns, and social isolation were found to be potential negative consequences of Internet addiction. ==Treatment==
