Several forms of treatment for nicotine dependence that combine the classical smoking cessation strategies with new Virtual Reality (VR) exposure techniques to smoking-related cues are in development. In this line, the main goal of our study was to develop a virtual platform in order to induce cravings in smokers. Sixty undergraduate students were randomly assigned to two different virtual environments (high-arousal cues and low-arousal cues). Both environments were based on a three-room apartment with commercial music playing and virtual characters interacting in a social event. The assessment was carried out before and after exposure through psychophysiological activation and self-report data for craving and nicotine dependence levels. No statistical differences were observed between smokers and non-smokers in psychophysiological activation. As far as self-report data is concerned, smokers revealed a significant increase in craving after the VR exposure to high arousal environments. Overall results were in line with previous studies suggesting the use of virtual environments as a tool for the existing smoking cessation programs.
几种将传统戒烟策略与针对吸烟相关线索的新型虚拟现实（VR）暴露技术相结合的尼古丁依赖治疗方法正在研发中。在此背景下，我们研究的主要目标是开发一个虚拟平台，以诱发吸烟者的烟瘾。60名本科生被随机分配到两种不同的虚拟环境（高唤醒线索和低唤醒线索）中。两种环境均基于一套三居室公寓，里面播放着商业音乐，虚拟角色在社交活动中互动。通过心理生理激活以及关于烟瘾和尼古丁依赖水平的自我报告数据，在暴露前后进行了评估。在心理生理激活方面，吸烟者和非吸烟者之间未观察到统计学差异。就自我报告数据而言，吸烟者在VR暴露于高唤醒环境后，烟瘾显著增加。总体结果与之前的研究一致，表明使用虚拟环境作为现有戒烟项目的一种工具。
