Cigarette craving is an important contributor to cigarette smoking, and clinical approaches that focus on regulation of craving are effective in reducing rates of relapse. However, a laboratory model that targets the use of cognitive strategies to regulate craving is lacking. To develop such a model, twenty heavy cigarette smokers (>12/day), twenty-two tobacco "chippers" (<6/day), and twenty non-smoking controls completed this outpatient study, during which they were presented with photographs of cigarettes and foods that have been previously shown to induce craving. During each trial, participants were instructed to think of the stimulus in one of two ways: by focusing either on the short-term consequences associated with consuming the item (e.g., it will taste good) or on the long-term consequences associated with regular consumption (e.g., I may get lung cancer). Participants reported significantly reduced food cravings when focusing on the long-term consequences associated with eating. For cigarette-smoking participants, cigarette craving was significantly reduced when focusing on the long-term consequences associated with smoking. This latter finding confirms clinical data and extends it by highlighting the importance of cognition in the modulation of craving. Future studies using this laboratory model could test the efficacy of different cognitive strategies and develop targeted interventions for smoking cessation based on the regulation of craving.
吸烟渴求(Cigarette craving)是导致吸烟的重要因素,针对该渴求进行调控的临床方法在降低复吸率方面是有效的。然而,目前缺乏针对使用认知策略来调控渴求的实验室模型。为了开发这样的模型,二十名重度吸烟者(>12 支/天)、二十二名烟草“浅尝者”(<6 支/天)和二十名不吸烟者完成了这项门诊研究,在此期间,他们被呈现了香烟和食物的照片,这些照片先前已被证明会引起渴求。在每次试验中,参与者被指示以两种方式之一思考刺激物:要么关注与消费该物品相关的短期后果(例如,它会很好吃),要么关注与经常消费相关的长期后果(例如,我可能会得肺癌)。参与者报告说,当专注于与进食相关的长期后果时,对食物的渴求明显减少。对于吸烟参与者,当专注于与吸烟相关的长期后果时,吸烟渴求明显减少。这一发现证实了临床数据,并通过强调认知在调节渴求中的重要性对其进行了扩展。未来使用这种实验室模型的研究可以测试不同认知策略的效果,并根据对渴求的调节为戒烟制定有针对性的干预措施。
