Abstract

Individuals with substance use disorder (SUD) show consistently higher delay discounting (DD) rates than controls for both future and past outcomes, as well as for gains and losses. However, differences in these DD effects (e.g., tense and sign) among individuals in SUD recovery have yet to be explored. Therefore, the goal of the present study was to (a) investigate differences in discounting of past and future gains and losses among individuals in SUD recovery and (b) examine differences in these DD effects between individuals in different stages of remission (i.e., not in remission, in early remission, or in sustained remission). Our results indicate that individuals in recovery discount past and future gains, but not losses, symmetrically. Additionally, individuals in recovery discount gains more than losses (i.e., sign effect) for the future but not for the past. Finally, those in sustained remission showed significantly lower DD rates than those not in remission, regardless of the DD task. Thus, other discounting tasks might provide a similarly accurate measure of DD and can be employed to assess differences in discounting between those in remission and those not in remission.

从物质使用障碍中恢复的个体对过去和未来收益和损失的差异贴现。
物质使用障碍(SUD)个体在未来和过去的结果以及收益和损失方面都表现出比对照组一贯更高的延迟折扣(DD)率。然而,这些DD效应(例如,紧张和体征)在个体SUD恢复中的差异尚未被探索。因此,本研究的目的是(a)调查个体在SUD恢复过程中对过去和未来得失的贴现差异,以及(b)检查不同缓解阶段(即未缓解、早期缓解或持续缓解)个体之间这些DD效应的差异。我们的研究结果表明,恢复中的个人会对称地贴现过去和未来的收益,而不是损失。此外,个人在恢复贴现收益大于损失(即,符号效应)的未来,而不是过去。最后,无论DD任务如何,持续缓解的患者的DD发生率明显低于未缓解的患者。因此,其他贴现任务可能提供类似的DD的精确测量,并可用于评估缓解者和未缓解者之间的贴现差异。(PsycInfo Database Record (c) 2025 APA,版权所有)。
