Transdermal nicotine almost doubles tobacco cessation rates; however, little is known about what happens to smokers during the quit process when they are wearing the nicotine patch and are confronted with high-risk smoking triggers. This is particularly important for smokers with psychological disorders who disproportionately represent today's smokers and have more trouble quitting. Using a mixed between- and within-subjects design, smokers with anxiety disorders (n=61) and smokers without any current Axis I disorders (n=38) received transdermal nicotine (21 mg) or a placebo patch over two assessment days separated by 48 hr. Urge to smoke was evaluated during a 5-hr patch absorption period (reflecting general smoking deprivation) and during imaginal exposure to theoretically high-risk triggers containing smoking cues, anxiety cues, both, or neutral cues. No differences were observed between smokers with and without anxiety disorders. Significant Patch×Time and Patch×Cue Content interactions were found. Both patch conditions experienced an increase in urge during the deprivation period, but postabsorption urge was significantly higher in the placebo condition, suggesting that transdermal nicotine attenuated the degree to which urge to smoke increased over time. During the cue reactivity trials, when participants received the nicotine patch, they experienced significantly lower urge in response to both smoking-only and neutral cues, but not when anxiety cues were present (alone or in combination with smoking cues). These data suggest that transdermal nicotine alleviates urge only under certain circumstances and that adjunctive interventions are likely necessary to address smoking urges in response to spikes in distress among smokers trying to quit.
经皮尼古丁贴片几乎使戒烟率翻倍;然而,当吸烟者佩戴尼古丁贴片并面临高风险吸烟触发因素时,他们在戒烟过程中会发生什么,目前知之甚少。对于患有心理障碍的吸烟者来说,这一点尤其重要,因为他们在今天的吸烟者中不成比例地代表了这一群体,并且更难以戒烟。本研究采用混合被试内和被试间设计,61 名焦虑障碍吸烟者和 38 名无任何当前轴 I 障碍的吸烟者在两天的评估中分别接受了经皮尼古丁(21mg)贴片或安慰剂贴片,两次评估间隔 48 小时。在 5 小时的贴片吸收期(反映一般吸烟剥夺)和想象暴露于理论上的高风险触发因素(包含吸烟线索、焦虑线索、两者或中性线索)期间,评估吸烟欲望。在有和没有焦虑障碍的吸烟者之间没有观察到差异。发现了显著的贴片×时间和贴片×线索内容的相互作用。在剥夺期,两种贴片条件下的吸烟欲望都有所增加,但在安慰剂条件下,吸收后的吸烟欲望明显更高,这表明经皮尼古丁减轻了随着时间的推移吸烟欲望增加的程度。在线索反应性试验中,当参与者接受尼古丁贴片时,他们对吸烟相关线索和中性线索的反应明显降低,但当只有焦虑线索存在(单独存在或与吸烟相关线索一起存在时),则不会降低。这些数据表明,经皮尼古丁仅在某些情况下缓解吸烟欲望,并且可能需要辅助干预来解决试图戒烟的吸烟者在出现压力激增时的吸烟欲望。
