Abstract

Objective: Understanding individuals who are successful in recovery from substance use disorders will help to inform treatments and preventative measures. Stress has been shown to be associated with both substance use and relapse. Delay discounting is associated with risk of substance use; it is predictive of treatment outcomes and maintained abstinence. Associations between perceived stress, beliefs about locus of control, and delay discounting have yet to be assessed in individuals in recovery from substance use disorder. Methods: Data from 93 individuals in recovery from substance use recruited from the International Quit and Recovery Registry (IQRR) were analyzed. Individuals completed the adjusting amount delay discounting procedure to obtain delay discounting rates. Level of perceived stress was assessed by the Perceived Stress Scale (PSS). An individual's belief about locus of control was assessed using the Internality, Powerful Others and Chance Scale (IPCS). Results: Delay discounting was a significant predictor of perceived stress and scores associated with beliefs about a Chance locus of control (i.e., belief that events that occur in an individual's life are because of chance or luck), even after controlling for demographic characteristics. Time in recovery was also predictive of levels of perceived stress; this relationship was mediated by delay discounting. Conclusion: The present study indicates that delay discounting can predict perception of stress and beliefs about a chance locus of control in individuals in recovery. This information may help understand, identify, and assist individuals whomay need different, new, or more intensive interventions for their substance use disorder.
