Delay discounting: trait variable?
TLDR
In analyses of archival data, positive correlations between the degree of delay discounting for one outcome (as measured by the Area Under the Curve), and the level of discounts for other outcomes suggest that delay discounts may be considered a personality trait.About:

Toward a theory of distinct types of "impulsive" behaviors: A meta-analysis of self-report and behavioral measures
TL;DR: Both independently predict problematic daily-life impulsive behaviors, such as substance use, gambling, and delinquency; their joint use has incremental predictive power over the use of either type of measure alone and furthers the understanding of these important, problematic behaviors.

Excessive discounting of delayed reinforcers as a trans-disease process contributing to addiction and other disease-related vulnerabilities: emerging evidence.
Warren K. Bickel,David P. Jarmolowicz,E. Terry Mueller,Mikhail N. Koffarnus,Kirstin M. Gatchalian +4 more
TL;DR: It is argued that delay discounting is a trans-disease process, undergirded by an imbalance between two competing neurobehavioral decision systems.

TL;DR: Those who met the diagnostic criteria for FA had a significantly greater co-morbidity with Binge Eating Disorder, depression, and attention-deficit/hyperactivity disorder compared to their age- and weight-equivalent counterparts.

The Behavioral Economics of Substance Use Disorders: Reinforcement Pathologies and Their Repair
TL;DR: The overall goal of this review is to present a new understanding of substance use disorders as viewed by recent advances in behavioral economics.

Delay Discounting: I'm a k, You're a k
TL;DR: The degree of delay discounting may be a personality trait and its study has provided the field of behavior analysis and other areas measures with robust generality and predictive validity for a variety of significant human problems.

Separate Neural Systems Value Immediate and Delayed Monetary Rewards
TL;DR: The authors examined the neural correlates of time discounting while subjects made a series of choices between monetary reward options that varied by delay to delivery and demonstrated that two separate systems are involved in such decisions.
Journal ArticleDOI
Heroin addicts have higher discount rates for delayed rewards than non-drug-using controls.
TL;DR: The authors found that delay-discounting rates are positively correlated with impulsiveness, a characteristic associated with substance abuse, as measured by self-report questionnaires (p <.05).

Impulsivity and cigarette smoking: delay discounting in current, never, and ex-smokers.
TL;DR: Cigarette smoking, like other forms of drug dependence, is characterized by rapid loss of subjective value for delayed outcomes, particularly for the drug of dependence.

Area under the curve as a measure of discounting
TL;DR: A novel approach to the measurement of discounting based on calculating the area under the empirical discounting function, which avoids some of the problems associated with measures based on estimates of the parameters of theoretical discounting functions.
