I found this article on google scholars and it was published in 2001. What's interesting about it is that it talks about VR and how is is still developing but has successfully integrated  in multiple areas of medicine and psychology. VR was used in surgical training, treatment of phobias, PTSD and eating disorders. It is also used to distract patients from the pain of dental work, burn treatment and chemotherapy. They state that one "benefit of VR is that it allows users to forget that they are in a simulation".Additionally it provides a safe learning environment that minimizes risks from error.

One of their first "efforts" was creating a virtual classroom and the simulation was aimed at children with ADHD. They created a realistic setting that featured objects that you would normally find in a classroom. They adjusted the simulation based on the age of the child. They monitored the child's "reaction time" to the instruction that they were given in the simulation. "Behavioural factors" such as being distracted and hyperactivity were assessed.

Conclusion
I thought that this article focused more on what exactly AV technology is and how it was used in a way to study patients with mental disorders. It keeps the patient physically safe for them to analyze their behaviour in the simulation. However in this article it questioned the ethics behind it. It might be safe physically for the patient but what about mentally.
