Introduction: Smartphones are often helpful in our everyday lives. Yet, they also tend to interrupt us during other activities. It has been argued that such distractions contribute to attention-deficit/hyperactivity disorder-like symptoms. However, since there are mostly correlational studies, the causal nature of this relationship is unclear. Our aim was to test whether reducing smartphone-related distractions might have a beneficial effect on inattention and hyperactive symptoms. Methods: We conducted a 1-week field experiment with 37 healthy undergraduates and quasi-randomly assigned them to an intervention or control group (CG). The intervention group was given theory-based specific instructions that aimed at reducing smartphone-related distractions, whereas the CG received no intervention. The outcomes of interest were inattention level, hyperactive symptoms, and working memory accuracy. Results: Compared to those in the control condition, participants who limited their smartphone use showed considerable reductions in hyperactive symptoms after 1 week – particularly those who displayed high problematic smartphone use. However, there were no group differences regarding inattention symptoms and working memory accuracy. Discussion: The results give a first hint that strategically reducing smartphone-related distractions via specific but simple use modifications can mitigate hyperactive symptoms. Especially people with problematic smartphone use seem to profit from such an intervention. Remaining questions and directions are discussed.

使用智能手机的更智能方式：限制与智能手机相关的干扰的干预措施可减少多动症，但不会减少注意力不集中的症状

简介：智能手机在我们的日常生活中通常很有帮助。然而，他们也倾向于在其他活动中打断我们。有人认为，这种分心会导致注意力缺陷/多动障碍样症状。然而，由于大多是相关性研究，这种关系的因果性质尚不清楚。我们的目的是测试减少与智能手机相关的分心是否可能对注意力不集中和多动症状产生有益影响。方法：我们对 37 名健康的本科生进行了为期 1 周的实地实验，并将他们半随机分配到干预组或对照组 (CG)。干预组获得了基于理论的具体指导，旨在减少与智能手机相关的干扰，而 CG 未接受任何干预。感兴趣的结果是注意力不集中程度、多动症状和工作记忆准确性。结果：与对照组相比，限制使用智能手机的参与者在 1 周后表现出多动症状显着减少——尤其是那些表现出严重问题的智能手机使用的参与者。然而，在注意力不集中症状和工作记忆准确性方面没有组间差异。讨论：结果给出了第一个提示，即通过特定但简单的使用修改策略性地减少与智能手机相关的干扰可以减轻多动症状。尤其是智能手机使用有问题的人似乎从这种干预中受益。讨论了剩余的问题和方向。
