In order to better understand why those higher in impulsivity experience more difficulties during smoking abstinence, the current study examined the possible mechanisms contributing to cigarette smoking relapse. Fifty dependent cigarette smokers completed measures designed to assess craving, tobacco withdrawal severity, and negative affect during 48 hours of nicotine abstinence. Using a series of multilevel models (SAS Proc Mixed Procedure), significant impulsivity x time analyses revealed differences in craving, F(2, 96) = 3.74, p<.05, and anxiety, F(2, 96) = 3.23, p<.05. Simple slopes analyses indicated that heightened trait-impulsivity predicted greater increases in craving and anxiety during a 48-hour abstinence period. These findings suggest that smokers with higher levels of impulsivity may lack the ability to find an accessible and comparable substitute for cigarette smoking during a cessation attempt. This study also highlights the importance of considering individual differences when treating those who wish to quit smoking.
为了更好地理解为什么冲动性较高的人在戒烟过程中会遇到更多困难，本研究探讨了导致吸烟复发的可能机制。五十名依赖香烟的吸烟者完成了旨在评估在48小时尼古丁戒断期间的渴望、烟草戒断严重程度和负面影响的测量。使用一系列多水平模型（SAS混合程序），显著的冲动性×时间分析显示在渴望方面存在差异，F(2, 96) = 3.74，p<.05，在焦虑方面也存在差异，F(2, 96) = 3.23，p<.05。简单斜率分析表明，特质冲动性增强预示着在48小时戒断期内渴望和焦虑的更大增加。这些发现表明，冲动性较高的吸烟者在戒烟尝试期间可能缺乏找到可及且可比的吸烟替代品的能力。本研究还强调了在治疗希望戒烟的人时考虑个体差异的重要性。
