Cigarette craving has been linked to elevated negative and positive moods, but a connection to deficient positive affect has not been studied. We tested whether a low hedonic capacity predicts a heightened urge to smoke after acute nicotine deprivation, and whether such an effect is mediated by decreased positive mood or increased negative mood. A total of 35 smokers characterized for individual differences in hedonic capacity were deprived of nicotine for 48 hr. Using mixed-effects regression modeling, we found that lower hedonic capacity predicted greater increases in craving 24 hr after nicotine withdrawal, t(29)=-2.33, p=.03. The effect of hedonic capacity on increased 24-hr postquit craving to smoke was fully mediated by decreased positive affect. Findings suggest that in early nicotine withdrawal, smokers with diminished capacity to experience pleasure have heightened susceptibility to cigarette cravings that arises because of decreased positive mood rather than increased negative mood.
对香烟的渴望与消极和积极情绪的升高有关,但与积极情感缺陷的联系尚未得到研究。我们测试了低享乐能力是否预示着急性尼古丁剥夺后吸烟冲动的增强,以及这种影响是否由积极情绪降低或消极情绪增加介导。共有35名具有享乐能力个体差异特征的吸烟者被剥夺尼古丁48小时。使用混合效应回归模型,我们发现享乐能力较低预示着尼古丁戒断24小时后渴望的更大增加,t(29)= -2.33,p = .03。享乐能力对戒烟后24小时吸烟渴望增加的影响完全由积极情感的降低介导。研究结果表明,在早期尼古丁戒断时,体验愉悦能力减弱的吸烟者对因积极情绪降低而非消极情绪增加而产生的香烟渴望更敏感。
