Modeling Internet Addiction

Most of us use the internet regularly. It has replaced earlier forms of communication like writing letters, reading news or magazines, phoning, or visiting. Many would agree that it is easier and more convenient than more traditional forms of communication. I also think that the stimulation of using the internet is far more rewarding than other formats offer. I can’t back that up with evidence, but I do know I look forward to checking my email, text messages, etc in much the same way that once a day checking of my mailbox offered (at least until adulthood when bills were often the most frequent arrivals!). Remember the wonderful surprise of finding a letter from a friend addressed to you! We currently have all kinds of places to ‘check’ for stimulation and reward on our computers or other electronic devices.

I am sometimes amazed at myself and others when I see the interest involved in electronic devices… including laptops, ipads, ipods, iphones, androids, and handheld electronic games (like the Nintendo DS). Our internet service was out for a few days this week and we were frustrated and annoyed that we were limited and could not interact with or easily check our devices as usual. It is interesting to reflect on how much we do rely on various forms of electronic communication.

An interesting study was done by Kwon & Chung (2011) studying the use of internet games by adolescents. They applied Baumeister’s escape from self theory (1991) to the phenomenon of pathologic use of internet games. Baumeister’s model has been used to understand other self-destructive behaviors including suicide and addictions to both substances and gambling. This model brings together many of the factors that prior research identifies as associated with internet game addiction, for example depressive symptoms, differences between real and idealized perceptions of self, escape from self, and interpersonal problems involving family and friends.

This model does not directly investigate the role of impulsivity and sensation seeking in internet game addiction. Kwon & Chung (2011) find that differences between real and idealized self perception are associated with depressive mood, which is associated with escape from self and also associated with internet game addiction. The study uses structural equation modeling to identify the strength and type of associations. However this form of modeling does not really offer a cause and effect analysis of events, it is based on cross sectional data which means all factors were present at the same time in participants. But it does establish that these relationships are important in the addiction behavior.

The authors identify that in Korean adolescents, use of internet games begins quite early. I suspect this is also true in other locations. I wonder about the changes that might be taking place in our brains and our children’s brains as we feed ourselves the stimulation readily available from electronic devices today. It is quite different from growing up with TV and radio – which was less satisfying given that you could not find material at any time of day that was personally satisfying and stimulating like we can today. The major factor missing in the study by Kwon is that there is no accounting for potential physiologic effects of electronic stimulation. The immediacy of gratification and plethora of forms of stimuli are so different than for prior experience and generations.

I think I will spend some free time exploring the internet for information about physiologic effects :) (who’s addicted?!) and perhaps I will see if I can buy an electronic version of Baumeister’s book on escape theory! If you know of work that has been done on the physiology let me know- send me a link or do tell about it in the comments!
