合成延迟奖励折扣（DRD）和成瘾严重程度和数量频率（QF）之间的连续关联;检查这些关系的调节因子;并调查发表偏倚。已发表研究的荟萃分析，检查DRD和成瘾行为之间的持续关联。通过PubMed、MEDLINE和PsycInfo确定了有关成瘾行为（酒精、烟草、大麻、兴奋剂、阿片类药物和赌博）的已发表、同行评审的研究。研究仅限于货币收益的DRD措施。使用Pearson r作为效应量进行随机效应荟萃分析。使用失效安全N、Begg-Mazumdar和Egger检验、发表年份和效应量的荟萃回归以及缺失研究的插补来评估发表偏倚。主要荟萃分析显示，效应量很小，但非常显着（r = 0.14，p < 10 - 14）。与QF（p = 0.01）相比，在检查严重程度的研究中观察到显著更大的效应量，但在成瘾行为类型（p = 0.30）或DRD评估（p = 0.90）之间没有观察到。发表偏倚指数表明，未发表的研究结果的影响不大。延迟奖励折扣与成瘾严重程度和数量频率的连续测量密切相关。这种关系在成瘾行为类型和延迟奖励折扣评估模式中通常是稳健的。
To synthesize continuous associations between delayed reward discounting (DRD) and both addiction severity and quantity-frequency (QF); to examine moderators of these relationships; and to investigate publication bias. Meta-analysis of published studies examining continuous associations between DRD and addictive behaviors. Published, peer-reviewed studies on addictive behaviors (alcohol, tobacco, cannabis, stimulants, opiates, and gambling) were identified via PubMed, MEDLINE, and PsycInfo. Studies were restricted to DRD measures of monetary gains. Random effects meta-analysis was conducted using Pearson’s r as the effect size. Publication bias was evaluated using fail-safe N, Begg-Mazumdar and Egger’s tests, meta-regression of publication year and effect size, and imputation of missing studies. The primary meta-analysis revealed a small magnitude effect size that was highly significant (r = 0.14, p < 10−14). Significantly larger effect sizes were observed for studies examining severity compared with QF (p = 0.01), but not between the type of addictive behavior (p = 0.30) or DRD assessment (p = 0.90). Indices of publication bias suggested a modest impact of unpublished findings. Delayed reward discounting is robustly associated with continuous measures of addiction severity and quantity-frequency. This relation is generally robust across type of addictive behavior and delayed reward discounting assessment modality.
