Recovery from substance use disorders is multifactorial with psychosocial functioning, such as quality of life (QOL), playing a particularly important role. Delay discounting, the degree to which individuals devaluate a reinforcer as a function of the delay to its receipt, is associated with QOL. Moreover, evidence shows that physical activity may decrease delay discounting rates. The present study aims to examine associations among physical activity, delay discounting, and QOL, and investigate the mediating role of delay discounting in the relationship between physical activity and QOL domains.
Data was collected from the International Quit & Recovery Registry (IQRR), and comprised of 267 participants (67% women) who reported being in recovery from substance use disorders. Participants completed the Health Behaviors Questionnaire (physical activity was measured using the fitness domain), a delay discounting minute task (higher delay discounting rates indicate a preference for smaller, sooner rewards), the World Health Organization QOL questionnaire, as well as demographics and substance use disorders-related questions. Multivariate linear regression was used to test associations between physical activity with delay discounting, and physical activity with each QOL domain. Mediation analyses were conducted to evaluate the mediating role of delay discounting in the relationship between physical activity and QOL domain.
Higher levels of physical activity were associated with greater valuation of the future (lower delay discounting rates; <.001) and higher levels of physical ( < .001), and environmental (=.001) QOL. Delay discounting mediated the relationship between physical activity and physical (=.004), and environmental (<.001) QOL.
Physical activity can be an important tool in the treatment and recovery of substance use disorders, as it is associated with future-oriented choices, which in turn contributes to improving the QOL of those individuals.
物质使用障碍的康复是多因素的，心理社会功能，如生活质量（QOL），起着特别重要的作用。延迟折扣，即个体根据强化物获得延迟程度对其进行贬值的程度，与生活质量相关。此外，有证据表明体育活动可能会降低延迟折扣率。本研究旨在探讨体育活动、延迟折扣和生活质量之间的关联，并研究延迟折扣在体育活动与生活质量领域关系中的中介作用。
数据收集自国际戒烟与康复登记处（IQRR），由267名报告从物质使用障碍中康复的参与者（67%为女性）组成。参与者完成了健康行为问卷（使用健身领域测量体育活动）、延迟折扣分钟任务（较高的延迟折扣率表明偏好较小、较快的奖励）、世界卫生组织生活质量问卷，以及人口统计学和物质使用障碍相关问题。多变量线性回归用于测试体育活动与延迟折扣之间的关联，以及体育活动与每个生活质量领域之间的关联。进行中介分析以评估延迟折扣在体育活动与生活质量领域关系中的中介作用。
较高水平的体育活动与对未来的更高估值（较低的延迟折扣率；<.001）以及更高水平的身体（<.001）和环境（=.001）生活质量相关。延迟折扣介导了体育活动与身体（=.004）和环境（<.001）生活质量之间的关系。
体育活动可以成为物质使用障碍治疗和康复的重要工具，因为它与面向未来的选择相关，这反过来有助于提高这些个体的生活质量。
