Both delay discounting and depression are risk factors for cigarette smoking during adolescence. However, very little research has explored associations between these variables in adolescent smokers and non-smokers.
Eighty adolescents were recruited based on depression status (depressed and non-depressed) and smoking status (smokers and non-smokers) to form four groups (n=20 per group). All participants completed a computerized monetary delay discounting task and a measure of depression.
Delay discounting and depression were significantly correlated. Also, smokers (both depressed and non-depressed) and depressed non-smokers all discounted significantly more than non-smokers who were not depressed. Depressed non-smokers and both groups of smokers did not differ in rate of delay discounting.
Adolescent non-smokers who are depressed discount similarly to adolescents who smoke and more than non-smokers who are not depressed. Future research should explore the unique versus shared roles of delay discounting and depression as risk factors for smoking during adolescence.
延迟折扣和抑郁都是青少年吸烟的风险因素。然而，极少有研究探讨青少年吸烟者和非吸烟者中这些变量之间的关联。
根据抑郁状态（抑郁和非抑郁）和吸烟状态（吸烟者和非吸烟者）招募了80名青少年，形成四组（每组n = 20）。所有参与者都完成了一项计算机化货币延迟折扣任务和一项抑郁测量。
延迟折扣与抑郁显著相关。此外，吸烟者（抑郁和非抑郁）以及抑郁的非吸烟者的折扣都显著高于非抑郁的非吸烟者。抑郁的非吸烟者和两组吸烟者在延迟折扣率上没有差异。
抑郁的青少年非吸烟者的折扣与吸烟的青少年相似，且高于非抑郁的非吸烟者。未来的研究应探讨延迟折扣和抑郁作为青少年吸烟风险因素的独特作用与共同作用。
