Delay discounting and depressive symptomatology have strong connections with smoking. However, few studies have examined interactions across delay discounting, depressive symptoms, and smoking status. The primary goal of this secondary analysis was to assess the interrelations across these 3 variables among treatment-seeking smokers. Delay discounting and depressive symptoms were assessed in 95 smokers enrolled in a clinical trial for smoking cessation at intake and 6-month follow-up. Participants with and without depressive symptoms did not differ in their discounting rates neither at intake nor at 6-month follow-up. However, delay discounting was significantly lower among abstainers at 6-month follow-up, and changes in discounting associated with smoking status were more pronounced among participants with depressive symptoms. These results clarify the relationship between delay discounting and depressive symptoms among current and former smokers and suggest that the association between smoking abstinence and lower delay discounting is significantly greater among individuals with depressive symptoms versus those who do not have depressive symptomatology.
延迟折扣与抑郁症状学和吸烟有着密切的联系。然而，很少有研究考察延迟折扣、抑郁症状和吸烟状况之间的相互作用。这项二次分析的主要目的是评估寻求治疗的吸烟者中这三个变量之间的相互关系。在一项戒烟临床试验中，对95名吸烟者在入组时和6个月随访时进行了延迟折扣和抑郁症状评估。有抑郁症状和无抑郁症状的参与者在入组时和6个月随访时的折扣率没有差异。然而，在6个月随访时，戒烟者的延迟折扣显著较低，并且在有抑郁症状的参与者中，与吸烟状况相关的折扣变化更为明显。这些结果阐明了当前吸烟者和既往吸烟者中延迟折扣与抑郁症状之间的关系，并表明与没有抑郁症状的个体相比，抑郁症状个体中戒烟与较低延迟折扣之间的关联显著更大。
