The elucidation of individual differences in tobacco use motivation is of considerable interest. Accordingly, the present study tested the hypothesis that between-person variation in reinforcement smoking (RS)--a tendency to smoke to regulate affect--moderates the relationship between poor mood and urge to smoke. In this cross-sectional, correlational study, smokers (N = 212; > or =5 cig/day) completed measures of RS, positive affect (PA), negative affect (NA), and smoking urge. RS significantly moderated the relation between PA and urge (betas > .11, ps < .04), such that the inverse correlation between PA and urge was stronger among smokers higher in RS. NA was positively correlated with urge in the overall sample (rs = .34, ps < .0001), but RS did not moderate this relationship. The overall results were consistent across 2 measures of mood and adjusted models that controlled for demographics and smoking characteristics. Continued investigation of these moderational pathways could identify which smokers may benefit most from treatments that target mood during smoking cessation.
个体在吸烟动机上的差异是相当值得关注的。因此，本研究检验了一个假设，即个体在吸烟调节情绪（RS）上的差异——一种通过吸烟来调节情绪的倾向——是否会调节情绪不佳和吸烟冲动之间的关系。在这项横断相关研究中，吸烟者（N=212；>或=5 支/天）完成了 RS、正性情绪（PA）、负性情绪（NA）和吸烟冲动的测量。RS 显著调节了 PA 和冲动之间的关系（β>.11，p<.04），即在 RS 较高的吸烟者中，PA 和冲动之间的负相关更强。在整个样本中，NA 与冲动呈正相关（rs=.34，p<.0001），但 RS 并没有调节这种关系。在考虑到人口统计学和吸烟特征的调整模型中，两种情绪测量方法的结果都是一致的。进一步研究这些调节途径可以确定哪些吸烟者可能最受益于针对戒烟期间情绪的治疗方法。
