Article Abstract
Background: Substance use disorder (SUD) and pain are highly comorbid conditions and several pain indices (e.g., pain intensity) are associated with an increased risk of relapse. However, the cognitive-emotional experience of pain (i.e., pain catastrophizing) is understudied in SUD recovery. Further, how the association between pain catastrophizing and delay discounting - a posited biomarker of addiction, impacts multidimensional aspects of SUD recovery, including remission and quality of life (QOL), has yet to be examined.
Methods: Individuals (n = 170) in SUD recovery reporting pain were asked about their chronic pain status, completed the Brief Pain Inventory, the Pain Catastrophizing Scale, an Adjusting Amount Delay Discounting Task, and the World Health Organization QOL-BREF scale. Univariate logistic and linear regressions examined associations between delay discounting and several pain indices with remission and QOL. Mediation analyses were investigated whether pain catastrophizing mediates the relationship between delay discounting and 1) sustained remission and 2) QOL.
Results: Significant negative associations were found between delay discounting (p < .001) and pain catastrophizing (p = .001) with sustained remission. Pain catastrophizing significantly mediated the relationship between delay discounting and physical QOL (p = .044), psychological QOL (p = .009), social (p = .018), and environmental QOL (p = .014). Pain catastrophizing did not mediate the relationship between DD and sustained remission.
Conclusion: Individuals with greater DD exhibited greater pain catastrophizing, contributing to poorer QOL in SUD recovery. Our findings support that a Reinforcer Pathology framework is useful to understanding the cognitive-emotional experience of pain within the context of SUD recovery. Interventions that target both delay discounting and maladaptive cognitive and emotional responses to pain may lessen the negative impact of pain on SUD recovery and improve SUD outcomes.

Perceived reward certainty in the assessment of delay discounting.
J Exp Anal Behav

Reward delays are often associated with reduced probability of reward, although standard assessments of delay discounting do not specify degree of reward certainty. Thus, the extent to which estimates of delay discounting are influenced by uncontrolled variance in perceived reward certainty remains unclear. Here we examine 370 participants who were randomly assigned to complete a delay discounting task when reward certainty was either unspecified (n=184) or specified as 100% (n = 186) in the task trials and task instructions.

Objectives: Previous studies failed to find age-related differences in the discounting of delayed, monetary losses, potentially due to their failure to examine the effects of income and their use of relatively small loss amounts. Accordingly, the present study examined the effects of age and income on the degree to which adults discount a broad range of loss amounts.
Methods: 594 participants (age range: 20 to 80; income range: <$30,000 to >$100,000) performed an adjusting-amount discounting task.
A discounting framework for trade-offs between risk and delay.

Every day we encounter situations in which decisions require trade-offs between the delay to one reward and the likelihood of receiving another reward. The current study was designed to extend a general discounting framework to gain insights into this fundamental trade-off process. Forty-three undergraduates adjusted the probability of receiving an immediate hypothetical monetary reward (either $200 or $10,000) until that probabilistic reward was judged subjectively equal in value to the same reward received with certainty after a delay (ranging from 1 month to 25 years).

Parkinson's disease (PD) is characterized by progressive neurodegeneration, which is associated with motor and non-motor symptoms. Dopamine replacement therapy can remediate motor symptoms, but can also cause impulse control disorder (ICD), characterized by pathological gambling, hypersexuality, and/or compulsive shopping. Approximately 14-40% of all medicated PD patients suffer from ICD.
