| Abstract: | Introduction: This study aimed to determine the role of perceived realism in the relationship between state anxiety and craving in virtual reality (VR) cue exposure therapy (CET) for individuals diagnosed with alcohol use disorder (AUD). Preliminary research already identified relationships between anxiety, craving and presence in VR-CET, whereas results are inconsistent. Moreover, the working mechanism of realism in the relationship between state anxiety and VR craving has not been examined. The objectives of this study were to (1) determine the role of perceived realism of VR environments and (2) investigate the role of perceived realism of VR beverages in the relationship between state anxiety and VR craving in VR CET. Methods: Twenty-one patients participated in this study. Their state anxiety was measured before a VR exposure and VR craving was measured during the exposure to different VR beverages. Further, the patients had to rate their perceived realism of (1) VR environments and (2) VR beverages. To analyse the role of the perceived realisms two mediation analyses were carried out. Results: Neither the perceived realism of VR environments nor the perceived realism of VR beverages were found to mediate the relationship between state anxiety and craving. Our data indicated a relationship between perceived realism VR beverages and VR craving. Conclusions: Results suggest that particularly VR realism beverages is relevant to generate VR craving. Although our data did not show an effect from state anxiety on the perceived realism, and from state anxiety on VR craving, relationships are still assumed based on a broad existing literature base. Verifying the given results in a controlled study with a larger sample size is warranted. |
