+ Introduction For most of us, Internet usage has no harmful effects, while for others poorly controlled and excessive preoccupations with the Internet lead to significant distress. The research on this particular topic is thriving, with fascinating findings being published worldwide.
+ Cross-Cultural Prevalence Statistics (See end of Research Map for full reference list) 1.2 million South Korean high school students are believed to be at risk for Internet addiction (Kim, 2007). A survey of British students revealed 18.3% were considered pathological users of the Internet (Niemz, Griffiths & Banyard, 2005). 3% of the German population (an estimated 1.5 million) are believed to be at risk of Internet addiction (Woefling, Buhler, Lemenager, Mairsen, & Mann, 2009). Of 17,251 survey respondents in the US, 6% fulfilled the Internet addiction criteria (Greenfield, 1999).
+ Diagnosing Problematic Internet Usage Internet Addiction is not currently listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), and so there are no widely accepted diagnostic criteria. However, it is proposed to be included in the future DSM-V (May 2013). In the meantime, experts have suggested the components essential to the diagnosis: 1. Excessive Internet use, associated with loss of time; 2. Withdrawal effects: tension, depression, anger; 3. Intense need for more hours of use and more computer equipment; 4. Adverse effects of Internet use: fatigue and social isolation for instance. See this article published in the American Journal of Psychiatry for more details on diagnosis criteria.
+ How to Measure Internet Addiction The Internet Addiction Scale is the most commonly used questionnaire for diagnosis and has been validated in Korea, Finland, the States and the UK, with a cut-off point score of 70 or above (Weinstein & Lejoyeux, 2010). Other popular questionnaires include: The Problematic Internet Use Questionnaire (PIUQ; validated in Hungary; Demetrovics, Szeredi, & Razsa, 2008). The Compulsive Internet Use Scale (CIUS; validated in Holland; Meerkerk, Van Den Eijnden, Vermulst, & Garretsen, 2009).
+ Internet Addiction and Sleep A study of high school Korean students with Internet addiction identified a 37.7% prevalence of excessive day time sleepiness (Choi et al., 2009). A high co-morbidity between Internet addiction and insomnia has also been reported (Cheung & Wong, 2011).
+ Internet Addiction, IQ and Social Effects In a study comparing Internet-addicted students (n=59) with non- addicted students (n=43), it was discovered that the former group scored significantly lower on the comprehension items of an IQ test. These comprehension items reflected reality testing and ethical judgement, thus indicating possible links between Internet addiction and weak social intelligence (Park et al., 2011).
+ Internet Addiction and its Association with other Disorders Interestingly, numerous studies have shown that Internet Addiction does not necessarily occur alone. Rather, other well-recognised disorders co-occur (co-morbidity), or predict the occurrence of problematic Internet usage.
+ Internet Addiction and its Association with other Disorders A prospective study on a sample of adolescents found Depression, Attention Deficit Hyperactivity Disorder (ADHD) and social phobia to predict Internet addiction at the follow-up data collection phase two years later (Ko, Yen, Chen, Yeh, & Yen, 2009). Davis (2001) found that the existence of a depressive disorder is one of the most significant predictors of excessive Internet use, while Fergusson, Boden, & Horwood (2009) found the reverse relationship: depressive symptoms are a consequence of excessive Internet use. Other studies suggest Internet addiction is associated with impulse control disorders and various chemical dependencies (e.g., Caplan, 2003; Shapira, Goldsmith, Keck, Kholsa, & McElroy, 2000).
+ Treating Internet Addiction Cognitive behavioural therapy (CBT) has been suggested as a suitable treatment. In particular, cognitive behavioural therapy- Internet addiction (CBT-IA): a three phase approach has been proposed: Phase 1) Behaviour modification is applied to gradually decrease the time the individual spends on the Internet. Phase 2) Cognitive therapy is applied to focus on the denial often experienced by the addicts with regards to their excessive online use. Phase 3) Harm reduction therapy (HRT) is applied to identify/ treat other issues present in the development of problematic Internet use. For anyone interested in this area, check out ‘CBT-IA: The First Treatment Model for Internet Addiction’ published in the Journal of Cognitive Psychotherapy: An International Quarterly (2011), by Dr Kimberly Young.
