In this study we examined the association between social discounting and smoking status in a cohort of pregnant cigarette smokers (n=91), quitters (n=27), or never-smokers (n=30). The smokers and quitters were participants in clinical trials on smoking cessation and relapse prevention, while the never-smokers were controls in a study on nicotine withdrawal during pregnancy. Social discounting was assessed using a paper and pencil task that assesses the amount of hypothetical money a person is willing to forgo in order to share with individuals in their social network ranging from the person who is emotionally closest to them to a mere acquaintance. The amount that women were willing to forgo in order to share decreased hyperbolically as a function of social distance, with smokers exhibiting steeper discounting functions (i.e., less generosity) than quitters or never-smokers; discounting functions of quitters and never-smokers did not differ significantly. In multivariate analyses controlling for potential sociodemographic and other confounds, social discounting remained a significant predictor of smoking status among smokers versus quitters. Overall, these results suggest that individual differences in social discounting may be a factor influencing the choices that women make about quitting smoking upon learning of a pregnancy.

社会折扣和怀孕期间吸烟

在这项研究中，我们在一组怀孕的吸烟者 (n=91)、戒烟者 (n=27) 或从不吸烟者 (n=30) 中检查了社会折扣与吸烟状况之间的关联。吸烟者和戒烟者是戒烟和预防复吸临床试验的参与者，而从不吸烟者是怀孕期间尼古丁戒断研究的对照组。社会折扣是使用纸笔任务评估的，该任务评估一个人愿意放弃的假设金钱数量，以便与他们社交网络中的个人分享，从情感上最接近他们的人到仅仅是熟人。女性为了分享而愿意放弃的数量作为社交距离的函数呈双曲线下降，吸烟者表现出更陡峭的贴现函数（即，不那么慷慨）比戒烟者或从不吸烟者；戒烟者和从不吸烟者的折扣功能没有显着差异。在控制潜在社会人口统计学和其他混杂因素的多变量分析中，社会折扣仍然是吸烟者与戒烟者吸烟状况的重要预测因素。总体而言，这些结果表明，社会折扣的个体差异可能是影响女性在得知怀孕后做出戒烟选择的一个因素。
