This study compared four treatment approaches to cigarette smoking: (1) a nicotine fading procedure, in which subjects changed their cigarette brands each week to ones containing progressively less nicotine and tar; (2) a self-monitoring procedure in which subjects plotted their daily intake of nicotine and tar; (3) a combined nicotine fading/self-monitoring procedure; and (4) a slightly modified American Cancer Society Stop Smoking Program. Thirty-eight habitual smokers were assigned to one of the treatment groups. The study had two goals: (1) to achieve a clinically significant percentage of abstinence, and (2) to reduce the nonabstainers' smoking to a "safer" level by having them smoke low tar and nicotine cigarettes. The 18-month followup results showed that the nicotine fading/self-monitoring group was the most successful: 40% were abstinent and all who had not quit were smoking cigarettes lower in tar and nicotine than their baseline brands. Half the nonabstainers had decreased their rate of smoking relative to baseline while the other half had increased. Furthermore, the fading/self-monitoring group achieved the largest reductions from baseline in daily nicotine and tar intake (61% and 70% respectively). The results suggest that the study's goals were achieved and that the nonaversive combined procedure could be used to treat not only habitual smokers but also smokers with severe cardiovascular and respiratory problems, because it does not have some of the inherent limitations of the successful aversive smoking cessation procedures.
(1)尼古丁递减程序,即受试者每周将其香烟品牌换成尼古丁和焦油含量逐渐降低的香烟;(2)自我监测程序,即受试者记录其每日尼古丁和焦油摄入量;(3)尼古丁递减/自我监测联合程序;以及(4)略有修改的美国癌症协会戒烟计划。38名习惯性吸烟者被分配到其中一个治疗组。该研究有两个目标:(1)实现具有临床意义的戒烟率,(2)通过让未戒烟者吸低焦油和低尼古丁香烟,将他们的吸烟量降低到“更安全”的水平。18个月的随访结果表明,尼古丁递减/自我监测组最为成功:40%的人戒烟,所有未戒烟者吸的香烟焦油和尼古丁含量均低于其基线品牌。一半的未戒烟者相对于基线降低了吸烟率,而另一半则有所增加。此外,递减/自我监测组的每日尼古丁和焦油摄入量相对于基线的降幅最大(分别为61%和70%)。结果表明该研究的目标得以实现,且这种无厌恶感的联合程序不仅可用于治疗习惯性吸烟者,还可用于治疗患有严重心血管和呼吸系统疾病的吸烟者,因为它没有一些成功的厌恶疗法戒烟程序所固有的局限性。
