Delayed reward discounting and addictive behavior: a meta-analysis.

ABSTRACT:

Rationale

Delayed reward discounting (DRD) is a behavioral economic index of impulsivity and numerous studies have examined DRD in relation to addictive behavior. To synthesize the findings across the literature, the current review is a meta-analysis of studies comparing DRD between criterion groups exhibiting addictive behavior and control groups.

Objectives

The meta-analysis sought to characterize the overall patterns of findings, systematic variability by sample and study type, and possible small study (publication) bias.

Methods

Literature reviews identified 310 candidate articles from which 46 studies reporting 64 comparisons were identified (total N=56,013).

Results

From the total comparisons identified, a small magnitude effect was evident (d= .15; p< .0
