"Social cognitive theory would warn that the high prevalence of interaction opportunities in the pro–eating disorder community has the potential to be extremely harmful if viewers are learning dangerous behaviors from one another, particularly if they are similar in age and gender. Other studies suggest that discussing techniques and perceived benefits may also have contagious effects on those not yet committed to the behaviors.5 The disclaimers included on pro–eating disorder Web sites may warn unsuspecting readers away from distressing content but also may entice vulnerable individuals to read further. Although there is no evidence as to the impact of warnings or disclaimers on pro–eating disorder sites, research on other media such as movies and video games with adult ratings suggests that labels might entice young viewers to want to see media that are not appropriate for them. Behavioral and communication theories, such as the social cognitive and cultivation theories mentioned earlier,8,9 would also suggest that the most deleterious components of these sites are the evocative images depicted coupled with constant social support encouraging extreme behaviors. On these Web sites, striving to be underweight is deemed not only as normative but as a signal of success. Only 13% of site maintainers offered an overt statement indicating that their own eating disorder was a problem. In addition, the Internet's easy accessibility allows users to tap into a site's features at any time of day or night. Social interaction is the most common reason young people use the Internet. This may be particularly relevant to the eating disorder online community, as research shows that individuals suffering from eating disorders have difficulty relating with same-age peers, attempt to hide their eating disorder behaviors, and often experience shame and isolation. Online venues for interaction with friends or strangers may seem like a safer and even appropriate place to disclose personal information. Furthermore, the Internet allows one to not only maintain relative anonymity but also easily retreat from criticism or uncomfortable situations."
