Neural responses to negative events and subsequent persistence behavior differ in individuals recovering from opioid...

Background: 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.Objectives: 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. Methods: 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 signal to negative events was analyzed within a striatum region of interest (ROI) as well as whole-brain.Results: The POUD group persisted less (t(38) = 2.293, p = .028, d = .725) and showed lower striatum (left ventral putamen) signal to negative events compared to the control group (p < .05, corrected for striatum ROI).Conclusions: 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.
