The importance of online social spaces is growing. New Web 2.0 resources allow the creation of social networks by any netizen with minimal technical skills. These communities can be extremely narrowly focussed. In this paper, I identify two potential costs of membership in narrowly focussed virtual communities. First, that narrowly focussed communities can polarise attitudes and prejudices leading to increased social cleavage and division. Second, that they can lead sick individuals to revel in their illness, deliberately indulging in their disease (...) and denying the edicts of the medical profession. I specifically examine illness communities centred on the now defunct Multiple Personality Disorder. I highlight these potential problems and point to some technologies that may help combat them.

The Internet is rapidly developing into an important medium of communication in modem society, and both psychological research and therapeutic interventions are being increasingly conducted using this new communication medium. As therapeutic interventions using the Internet are becoming more prevalent, it is becoming increasingly important to conduct research on psychotherapeutic Internet interventions to assist in the development of an appropriate standard of practice regarding interventions using this new medium. In this article, we examine the Internet and the current psychological uses (...) which are being initiated using this medium. Ethical concerns related to the psychological use of the Internet are discussed, and guidelines are proposed for the conduct of Internet intervention research. (shrink)
