Use of virtual reality in forensic psychiatry

Abstract

For more than 20 years virtual realities (VR) have been successfully used in the assessment and treatment of psychiatric disorders. The most important advantages of VR are the high ecological validity of virtual environments, the entire controllability of virtual stimuli in the virtual environment and the capability to induce the sensation of being in the virtual environment instead of the physical environment. VRs provide the opportunity to face the user with stimuli and situations which are not available or too risky in reality. Despite these advantages VR-based applications have not yet been applied in forensic psychiatry. On the basis of an overview of the recent state-of-the-art in VR-based applications in general psychiatry, the article demonstrates the advantages and possibilities of VR-based applications in forensic psychiatry. Up to now only preliminary studies regarding the VR-based assessment of pedophilic interests exist. These studies demonstrate the potential of ecologically valid VR-based applications for the assessment of forensically relevant disorders. One of the most important advantages is the possibility of VR to assess the behavior of forensic inpatients in crime-related situations without endangering others. This provides completely new possibilities not only regarding the assessment but also for the treatment of forensic inpatients. Before utilizing these possibilities in the clinical practice exhaustive research and development will be necessary. Given the high potential of VR-based applications, this effort would be worth it.
