Why a Computerized Decision System does not always lead to the Correct DSM-Classification
According to Lars Bergman there are several reasons that keep computerized systems from producing the correct DSM-classification. The most important point might be that diagnosis in psychiatry is just to complex for a fully structured system to reach a good level of validity. Dynamic systems and appropriate statistics might be necessary. According to Dreyfus the intuition of the expert is an important part of the diagnostic process. This would also mean that the (paper version of the) SCID does not yield the expected validity. Other reasons are related to methodological problems of the study at hand: Most physicians used the computer version of the SCID for the first time. They also received only limited training and thus the computerized process might have interfered with their normal skills. Also the rule-following and logical step-by-step procedures designed for non-experts might have influenced validity.
Three Recent Applications of Virtual Reality in Psychotherapy Training
http://www.vrphobia.com (which turned up as #1 in Google) is an organization that is called Virtual Reality Medical Center. They treat all kinds of anxiety related disorders, but seem to focus mainly on specific phobias. After the intake session the client is taught skills to suppress automatic fear reactions. In the following sessions the client is gradually exposed to the feared stimulus. In other words: VR desensitisation.

Obesity and addiction have some common properties. This research seeks to integrate some findings of addiction research into eating disorder therapy. In that light they make use of VR for distinct goals: Help the client to experience the own body in situations that are normally avoided. This experience is supposed to have influence on body perception and also empower the client. In the VR patients came “face to screen” with their personal risk situations (supermarket, gym, etc…) and could train emotion regulation and problem-solving skills in a save environment. The randomized clinical trial seems to indicate that the ECT group did indeed better than standard CBT.
As http://www.cybertherapy.info/cybertherapy/8_Optale.pdf shows also psycho-dynamic therapists start to see the merits in using new technology. Erection dysfunction and premature ejaculation are treated in a virtual environment (the porn industry will love that application) together with standard psychotherapy. The possibility to enact the new strategies in a save and private environment is supposed to speed up the therapeutic process. First clinical trials seem to indicate that this might indeed work for some clients, also it is not clear for whom exactly. Sample size is not adequate in study 1, power is much stronger in study 2. Results are not telling a clear story (yet?).
By the way:
http://www.cybertherapy.info/ is the most comprehensive and excellent source for material about VR in psychotherapy that I could find on the net. Especially have a look at the free books, like http://www.cybertherapy.info/pages/book2.htm or http://www.cybertherapy.info/pages/book3.htm. The articles are downloadable as PDF (just scroll down). Especially look at book 3 session 2 that comprises some clinical controlled trials with cybertherapy (which seems to be the keyword I was desperately looking for).
