Research has generally demonstrated that the discounting of delayed rewards is associated with severity of addictive behaviour. Less clear, however, is the relative strength of the relation for specific addictive behaviours. University students (N=218) completed a computerized delay discounting task for hypothetical monetary rewards, and gambling, cannabis, and alcohol problem severity was assessed. A multiple regression analysis revealed that while the overall model was significant, only gambling problem severity accounted for delay discounting scores above and beyond cannabis and alcohol problem severity. The results support the hypothesis that delay discounting of hypothetical monetary rewards is more associated with gambling than other addictive behaviour problems, including substance use problems.
研究总体上表明，延迟奖励的折扣与成瘾行为的严重程度相关。然而，对于特定成瘾行为而言，这种关系的相对强度尚不清楚。218名大学生完成了一项针对假设货币奖励的计算机化延迟折扣任务，并评估了赌博、大麻和酒精问题的严重程度。多元回归分析显示，虽然整体模型具有显著性，但只有赌博问题严重程度能够解释在大麻和酒精问题严重程度之外的延迟折扣分数。结果支持了这样一种假设，即假设货币奖励的延迟折扣与赌博的关联比与包括物质使用问题在内的其他成瘾行为问题的关联更强。
