: Negative emotion is associated with substance craving and use in individuals recovering from substance use disorders, including prescription opioid use disorder (POUD). Decisions to abandon or persist towards a goal after negative emotion-eliciting events, and neural responses that shape such decisions, may be important in maintaining recovery from POUD.: We examined differences in neural responses to negative events and subsequent persistence decisions in individuals recovering from POUD without a history of a substance use disorder. : 20 individuals with POUD (POUD group: 4 females, abstinent 2-3 weeks after admission to an inpatient treatment facility post-detoxification, no other substance use disorder), and 20 individuals with no substance use history (control group: 6 females) completed a persistence-after-setbacks task during functional magnetic resonance imaging. Participants advanced along a path toward a reward; after encountering each negative event (i.e., progress-erasing setback), participants made decisions to persist or abandon the path. Persistence decision rates were compared between groups and blood-oxygen-level-dependent to negative events was analyzed within a striatum region of interest (ROI) as well as whole-brain.: The POUD group persisted less (t(38) = 2.293, = .028, d = .725) and showed lower striatum (left ventral putamen) signal to negative events compared to the control group ( < .05, corrected for striatum ROI).: In POUD, neural and behavioral responses to negative events differ from controls. These differences are a target for research to address whether POUD treatment increases persistence and striatum responses to negative events and improves recovery outcomes.
消极情绪与物质成瘾和使用有关,包括从物质使用障碍中恢复的个体,包括处方阿片类药物使用障碍(POUD)。在经历引发消极情绪的事件后,放弃或坚持目标的决策,以及塑造这些决策的神经反应,可能对从 POUD 中恢复至关重要:我们研究了在没有物质使用障碍史的 POUD 个体中,对消极事件的神经反应和随后的坚持决策的差异。
20 名 POUD 个体(POUD 组:4 名女性,在出院后 2-3 周内从住院治疗设施中戒毒,没有其他物质使用障碍)和 20 名没有物质使用史的个体(对照组:6 名女性)在功能磁共振成像期间完成了坚持后挫折任务。参与者沿着一条通向奖励的路径前进;遇到每个负面事件(即,进度擦除挫折)后,参与者做出坚持或放弃路径的决定。在两组之间比较了坚持决策率,并在纹状体感兴趣区域(ROI)内以及整个大脑内分析了对负面事件的血氧水平依赖性。
与对照组相比,POUD 组的坚持程度较低(t(38)=2.293, = 0.028, d = 0.725),对负面事件的纹状体信号(左腹侧苍白球)也较低( < 0.05,校正为纹状体 ROI)。
在 POUD 中,对负面事件的神经和行为反应与对照组不同。这些差异是研究的目标,旨在确定 POUD 治疗是否会增加坚持和对负面事件的纹状体反应,并改善恢复结果。
