冲动控制障碍(ICD)行为和问题互联网使用(PIU)之间的关系已经在文献中建立。我们的目的是进一步调查患有PIU的个体的ICD是否主要涉及无法延迟满足或倾向于冒险。采用延迟贴现和概率贴现任务，比较了PIU个体和对照组在获得或损失不同金额条件下的贴现主观价值。本研究的结果显示，PIU与冲动性得分呈显著正相关。与对照组相比，PIU个体对延迟金额的贴现幅度更大，无论奖励标志和金额如何。相反，在概率贴现任务中，没有显著的组间差异。这些发现表明，当冲动被定义为对延迟结果不敏感而不是冒险倾向时，PIU个体可能比对照组更冲动，这与冲动是一种一般特征的观点不一致。
The relationship between impulse control disorder (ICD) behaviors and problematic Internet use (PIU) has been established in the literature. Our aim was to further investigate whether the ICDs of individuals suffering from PIU primarily involve an inability to delay gratification or a tendency to take risks. Using delay and probability discounting tasks, we compared the subjective value of discounting between PIU individuals and controls in conditions of gaining or losing different monetary amounts. The results of the present study revealed a significant positive relationship between PIU and impulsivity scores. PIU individuals discounted delayed amounts more steeply than controls, regardless of the reward sign and monetary amount. Conversely, there were no significant group differences in the probability discounting task. These findings suggest that PIU individuals may be more impulsive than controls when impulsivity is framed as insensitivity to delayed outcomes rather than as a tendency to take risks, which is inconsistent with the view of impulsivity as a general trait.
