简要总结
Alcohol use disorder (AUD) is a burdensome clinical disorder with high relapse rates. Virtual Reality (VR)-based therapeutic and diagnostic approaches have received increasing attention in the treatment of AUD but evidence on the induction of craving via VR scenarios is still needed. Craving for alcohol is associated with psychological and physiological responses. This single-arm clinical study will be conducted including n=60 patients with AUD. Using a head-mounted display (HMD), patients will be confronted with three different VR scenarios (neutral vs. two target situations) while heart rate, heart rate variability (HRV), pupillometry and electrodermal activity (EDA) will be measured continuously. Subjective craving levels will be assessed pre-/during/post-exposure to each VR scenario.

结局指标
主要结局
change in psychophysiological craving levels (heart rate variability) elicited by alcohol-associated cues
时间窗: 20-30 min VR exposure
Changes in craving levels measured continuously by heart rate variability (ms) during VR-exposure to alcohol-associated cues compared to neutral cues.
change in subjective craving levels elicited by alcohol-associated cues
时间窗: 20-30 min VR exposure
Changes in craving levels measured by subjective parameters (visual analogue scale = VAS, scale 0-100) before, during and after VR-exposure to alcohol-associated cues compared to neutral cues
change in psychophysiological craving levels (heart rate) elicited by alcohol-associated cues
时间窗: 20-30 min VR exposure
Changes in craving levels measured continuously by heart rate (bpm = beats per minute) during VR-exposure to alcohol-associated cues compared to neutral cues.
change in psychophysiological craving levels (electrodermal activity) elicited by alcohol-associated cues
时间窗: 20-30 min VR exposure
Changes in craving levels measured continuously by electrodermal activity (micro-Siemens) during VR-exposure to alcohol-associated cues compared to neutral cues.
change in psychophysiological craving levels elicited by alcohol-associated cues
时间窗: 20-30 min VR exposure
Changes in craving levels measured continuously by pupillometry (pupil dilation in mm) during VR-exposure to alcohol-associated cues compared to neutral cues.
次要结局
- development of subjective craving levels post-exposure(3 hours after VR-exposure)
- context-related change in craving levels(20-30 minutes VR Exposure)
