Abstract:Cognitive behavioral therapy (CBT) with Exposure and Response Prevention (ERP) in virtual reality (VR) is a promising new approach to treat Obsessive-Compulsive Disorder (OCD) as it has potential to tackle the existing treatment gap. The efficiency of VR interventions is highly dependent on a mechanism commonly referred to as sense of presence. The aim of this study is to investigate factors influencing sense of presence in an ERP for VR intervention targeting OCD. 40 participants experiencing contamination or checking compulsion were screened for their sense of presence upon completion of an intervention which took place in two separate and customized virtual environments. We expected participants experiencing contamination compulsions to display a higher sense of presence than participants experiencing checking compulsions, as well as males to experience a higher sense of presence than females. Finally, we expected to see a negative relationship between cybersickness and sense of presence and for this relationship to be more pronounced in the older population. No significant group differences were found for the main hypotheses. Technical improvements such as advanced graphics and additional sensory cues might be needed to ensure an immersive experience for participants and allow appropriate group comparisons.
