Laboratory exposure to alcoholic beverage cues has been demonstrated to elicit urges to drink. Less well examined is the possibility that imaginal cues also elicit such urges, providing a model of conditioned effects not dependent on the presence of physical stimuli associated with alcohol. Studies of possible cross-reactivity between smoking and drinking cues are also scarce. To that end, nicotine-dependent nonalcoholic smokers (n=54) were exposed to social drinking-relevant, and for comparison, neutral and smoking-relevant standardized script-guided imagery. Cravings were measured before and after each imaginal exposure. As hypothesized, the drinking script induced alcohol and cigarette cravings, providing support for both direct and cross-cue reactivity effects. Further validating the social-drinking script, craving reactions were significantly stronger among participants who reported frequent drinking in social situations. Finally, smoking imagery induced both cigarette and alcohol cravings, providing further support for the cross-cue-induced craving phenomenon. Results suggest that the present alcohol script may be a useful tool for eliciting craving responses under laboratory conditions, and provide an additional means for better understanding addiction.
实验室暴露于酒精饮料线索已被证明会引发饮酒冲动。想象线索是否也会引发此类冲动,从而提供一种不依赖于与酒精相关的物理刺激存在的条件作用模型,这方面的研究较少。关于吸烟和饮酒线索之间可能的交叉反应性的研究也很匮乏。为此,对54名尼古丁依赖的非酒精吸烟者进行了研究,让他们接触与社交饮酒相关的、作为对照的中性以及与吸烟相关的标准化脚本引导意象。在每次意象暴露前后测量渴望程度。正如所假设的,饮酒脚本引发了对酒精和香烟的渴望,这为直接和交叉线索反应效应提供了支持。进一步验证社交饮酒脚本的是,在社交场合频繁饮酒的参与者中,渴望反应明显更强。最后,吸烟意象引发了对香烟和酒精的渴望,为交叉线索引发的渴望现象提供了进一步支持。结果表明,目前的酒精脚本可能是在实验室条件下引发渴望反应的有用工具,并为更好地理解成瘾提供了额外手段。
