渴望被认为是戒烟后复吸的主要因素之一。线索暴露疗法（CET）包括控制和重复暴露于药物相关刺激，以消除相关反应。本研究的主要目的是评估7个虚拟现实环境的有效性，吸烟者产生渴望，可以在CET范式内使用。46名吸烟者和44名从不吸烟者被暴露在7个复杂的虚拟环境中，这些环境具有与吸烟相关的线索，重现了人们吸烟的典型情况，并暴露在没有吸烟线索的中性虚拟环境中。自我报告的主观渴望和心理生理措施，记录在曝光。所有虚拟环境与吸烟相关的线索能够产生主观渴望吸烟者，而没有增加观察到的中性环境。最敏感的心理生理变量的渴望增加是心率。这些发现为虚拟现实模拟能够引发渴望的真实的情况的实用性提供了证据。我们还讨论了如何通过这些虚拟工具来改善戒烟的CET。(C)2012爱思唯尔有限公司保留所有权利。
Craving is considered one of the main factors responsible for relapse after smoking cessation. Cue exposure therapy (CET) consists of controlled and repeated exposure to drug-related stimuli in order to extinguish associated responses. The main objective of this study was to assess the validity of 7 virtual reality environments for producing craving in smokers that can be used within the CET paradigm. Forty-six smokers and 44 never-smokers were exposed to 7 complex virtual environments with smoking-related cues that reproduce typical situations in which people smoke, and to a neutral virtual environment without smoking cues. Self-reported subjective craving and psychophysiological measures were recorded during the exposure. All virtual environments with smoking-related cues were able to generate subjective craving in smokers, while no increase was observed for the neutral environment. The most sensitive psychophysiological variable to craving increases was heart rate. The findings provide evidence of the utility of virtual reality for simulating real situations capable of eliciting craving. We also discuss how CET for smoking cessation can be improved through these virtual tools. (C) 2012 Elsevier Ltd. All rights reserved.
