Debates concerning the impacts of screen time are widespread. Existing research presents mixed findings, and lacks longitudinal evidence for any causal or long-term effects. We present a critical account of the current shortcomings of the screen time literature. These include poor conceptualisation, the use of non-standardised measures that are predominantly self-report, and issues with measuring screen time over time and context. Based on these issues, we make a series of recommendations as a basis for furthering academic and public debate. These include drawing on a user-focused approach in order to seek the various affordances gained from "screen use". Within this, we can better understand the way in which these vary across time and context, and make distinction between objective measures of "screen time" compared to those more subjective experiences of uses or affordances, and the differential impacts these may bring.
关于屏幕时间影响的争论广泛存在。现有研究结果喜忧参半，缺乏关于任何因果关系或长期影响的纵向证据。我们对当前屏幕时间文献的不足之处进行了批判性的评价。这些不足之处包括概念化不充分、使用非标准化的主要是自我报告的测量方法，以及在时间和背景上测量屏幕时间的问题。基于这些问题，我们提出了一系列建议，作为进一步开展学术和公众讨论的基础。这些建议包括借鉴以用户为中心的方法，以寻求从“屏幕使用”中获得的各种功能。在这方面，我们可以更好地理解这些功能随时间和背景的变化方式，并区分“屏幕时间”的客观测量与使用或功能的更主观体验，以及这些可能带来的不同影响。
