Delay discounting refers to one process by which an individual devalues delayed outcomes. Typical discounting tasks provide no information about events during delays to larger-later rewards. Imposing opportunity costs during the delay increases how steeply delayed rewards are discounted (P. S. Johnson, Herrmann, & Johnson, 2015). The present research evaluated whether distress tolerance (i.e., one's ability to tolerate distressing emotions and events) is related to discounting rates when opportunity costs are low, high, or unspecified. In a sample of predominantly female college students, we partially replicated that delay discounting was related to distress tolerance when opportunity costs were unspecified (significant relations confined to particular facets of distress tolerance), but distress tolerance was not related to delay discounting when opportunity costs were specified as low or high. The nature of the relation between distress tolerance and discounting when opportunity costs were unspecified was clarified by a significant interaction between alcohol use and distress tolerance; distress tolerance was unrelated to delay discounting except among participants with problematic alcohol use. Further research is needed to characterize relations between alcohol use, distress tolerance, and delay discounting and inform prevention and treatment efforts in at-risk populations.

延迟折扣是指个体对延迟结果进行贬值的一种过程。典型的折扣任务不会提供关于延迟至更大后期奖励期间事件的任何信息。在延迟期间施加机会成本会增加延迟奖励被折扣的陡峭程度(P.S. 约翰逊、赫尔曼和约翰逊,2015年)。本研究评估了痛苦耐受性(即一个人容忍痛苦情绪和事件的能力)在机会成本低、高或未明确时是否与折扣率相关。在一个以女性为主的大学生样本中,我们部分重复了在机会成本未明确时延迟折扣与痛苦耐受性相关的结果(显著关系仅限于痛苦耐受性的特定方面),但当机会成本被指定为低或高时,痛苦耐受性与延迟折扣无关。酒精使用与痛苦耐受性之间的显著交互作用阐明了机会成本未明确时痛苦耐受性与折扣之间关系的性质;除了有酒精使用问题的参与者外,痛苦耐受性与延迟折扣无关。需要进一步的研究来描述酒精使用、痛苦耐受性和延迟折扣之间的关系,并为高危人群的预防和治疗工作提供信息。(PsycINFO数据库记录)
