Research on delay discounting (DD) is mixed on whether DD is a domain-specific component related to specific behaviors or a domain-general process that cuts across various behaviors. A pivotal group to test the associations between DD and unhealthy behaviors is individuals in recovery from substance use disorders (SUD), as they are moving away from a disorder toward a healthier state.
Individuals in SUD recovery (n = 317) completed the Temptation Scale, the Health Behaviors Questionnaire, and an Adjusting Delay Discounting Task. An exhaustive model space search was performed using linear regression to examine associations between DD with temptation, engagement in unhealthy behaviors, and the total number of unhealthy behaviors participants engage in. We also tested whether remission status is associated with the total number of unhealthy behaviors participants engage in.
Results revealed that DD was positively associated with poor eating (p<.001), physical inactivity (p=.003), financial irresponsibility (p<.001), risky behaviors (p<.001), lack of personal development goals (p<.001), lack of household savings (p=.004), and lack of health behaviors (p=.003). DD was also positively associated with the total number of unhealthy behaviors participants engage in (p<.001). Participants who were not in remission engaged in more unhealthy behaviors compared to those who were in remission (p<.001).
In a sample of individuals in recovery from SUD, DD is not domain-specific and undergirds engagement in several maladaptive health behaviors that can negatively impact recovery. Thus, DD can be a target for interventions aiming to reduce other maladaptive behaviors in SUD recovery.
关于延迟折扣（DD）的研究结果不一，其究竟是与特定行为相关的特定领域成分，还是跨越各种行为的普遍领域过程，尚无定论。检验 DD 与不健康行为之间关联的关键人群是物质使用障碍（SUD）康复者，因为他们正在从疾病状态向更健康的状态转变。
SUD 康复者（n=317）完成了诱惑量表、健康行为问卷和调整延迟折扣任务。采用线性回归对详尽的模型空间进行搜索，以检验 DD 与诱惑、参与不健康行为以及参与者参与的不健康行为总数之间的关联。我们还测试了缓解状态是否与参与者参与的不健康行为总数有关。
结果表明，DD 与不良饮食（p<.001）、身体活动不足（p=.003）、财务不负责任（p<.001）、冒险行为（p<.001）、缺乏个人发展目标（p<.001）、缺乏家庭储蓄（p=.004）和缺乏健康行为（p=.003）呈正相关。DD 还与参与者参与的不健康行为总数呈正相关（p<.001）。未缓解的参与者比缓解的参与者参与更多的不健康行为（p<.001）。
在 SUD 康复者样本中，DD 不是特定领域的，而是支持参与多种适应不良的健康行为，这些行为可能会对康复产生负面影响。因此，DD 可以作为旨在减少 SUD 康复中其他适应不良行为的干预措施的目标。
