ABSTRACT
INTRODUCTION:
Virtual reality (VR) has been shown to be effective in eliciting responses to nicotine cues in cigarette smokers. The primary aim of this study was to investigate whether cigarette-deprived smokers would exhibit increased craving and changes in heart rate when viewing cigarette related cues as compared to non-smoking cues in a VR environment, and the secondary aim was to assess the extent to which self-assessed measures of withdrawal and dependence correlated with VR craving.METHODS:
Nicotine-dependent cigarette smokers were recruited for a 2 day study. On Day 1, participants smoked as usual and on Day 2 were deprived from smoking overnight. On both days, participants completed self-assessment questionnaires on withdrawal, craving, and nicotine-dependence. Participants completed a VR session during the cigarette deprivation condition only (Day 2). During this session, they were exposed to active smoking and placebo (non-smoking) cues.RESULTS:
The data show that self-reported levels of "craving" (p < .01) and "thinking about cigarettes" (p < .0001) were significantly greater after exposure to the active cues versus non-smoking cues. Significant increases in heart rate were found for 3 of 4 active cues when compared to non-smoking cues (p < .05). Finally, significant positive correlations were found between self-reported craving prior to the VR session and craving induced by active VR cues (p < .01).CONCLUSIONS:
In this report, active VR cues elicited craving during cigarette deprivation. This is the first study to demonstrate that self-reported craving, withdrawal symptoms, and nicotine dependence severity predict cue-induced craving in the VR setting.
