背景和目的：像Facebook这样的在线社交网站为用户提供了无数的社交奖励。这些社交奖励让用户反复回到社交网站，一些用户表现出不适应、过度使用社交网站。这种过度使用社交网络的症状与物质使用和行为成瘾障碍的症状相似。重要的是，有物质使用和行为成瘾障碍的个体很难做出基于价值的决定，正如爱荷华赌博任务（IGT）等范例所证明的那样；然而，目前尚不清楚过多的社交网络用户是否也表现出同样的决策缺陷。因此，在本研究中，我们旨在调查过度使用社交网络与IGT表现之间的关系。方法：我们对71名参与者使用Bergen Facebook成瘾量表（BFAS）来评估他们对Facebook SNS的不良使用。接下来，我们让他们对IGT进行了100次试验，以评估他们基于价值的决策。结果：我们发现BFAS评分与IGT表现之间存在负相关，特别是在最后20个试验中。在早期的试验中，BFAS评分和IGT表现之间没有相关性。讨论：我们的研究结果表明，更严重的、过度的社交网络使用与更缺乏基于价值的决策有关。特别是，我们的研究结果表明，过度使用SNS可能会在IGT任务中做出更冒险的决定。结论：这一结果进一步支持了有问题的、过度使用社交网络的个体与物质使用和行为成瘾障碍个体之间的平行关系。
Background and aims: Online social networking sites (SNSs) like Facebook provide users with myriad social rewards. These social rewards bring users back to SNSs repeatedly, with some users displaying maladaptive, excessive SNS use. Symptoms of this excessive SNS use are similar to symptoms of substance use and behavioral addictive disorders. Importantly, individuals with substance use and behavioral addictive disorders have difficulty making value-based decisions, as demonstrated with paradigms like the Iowa Gambling Task (IGT); however, it is currently unknown if excessive SNS users display the same decision-making deficits. Therefore, in this study, we aimed to investigate the relationship between excessive SNS use and IGT performance. Methods: We administered the Bergen Facebook Addiction Scale (BFAS) to 71 participants to assess their maladaptive use of the Facebook SNS. We next had them perform 100 trials of the IGT to assess their value-based decision making. Results: We found a negative correlation between BFAS score and performance in the IGT across participants, specifically over the last block of 20 trials. There were no correlations between BFAS score and IGT performance in earlier blocks of trials. Discussion: Our results demonstrate that more severe, excessive SNS use is associated with more deficient value-based decision making. In particular, our results indicate that excessive SNS users may make more risky decisions during the IGT task. Conclusion: This result further supports a parallel between individuals with problematic, excessive SNS use, and individuals with substance use and behavioral addictive disorders.
