研究：屏幕使用时间对健康影响不大

Data from more than 17,000 teenagers show little evidence of a relationship between screen time and well-being¹ in adolescents.

 

从17000名青少年中收集的数据显示，很少的证据表明屏幕使用时间和青少年的健康存在联系。

 

The study, published in Psychological Science, a journal of the Association for Psychological Science, casts doubt on the widely accepted notion that spending time online, gaming, or watching TV, especially before bedtime, can damage young people's mental health.

 

"Implementing² best practice statistical³ and methodological techniques we found little evidence for substantial negative associations between digital-screen engagement and adolescent well-being," said Amy Orben, a Researcher at the Oxford⁴ Internet Institute (OII) and College Lecturer at the Queen's College, University of Oxford.

 

"While psychological science can be a powerful tool for understanding the link between screen use and adolescent well-being, it still routinely fails to supply stakeholders and the public with high-quality, transparent⁵, and objective investigations⁶ into growing concerns about digital technologies."

 

"Analyzing⁷ three different datasets, which include improved measurements of screen time, we found little clear-cut evidence that screen time decreases adolescent well-being, even if the use of digital technology occurs directly before bedtime," said Professor Andrew Przybylski, Director of Research at the OII and coauthor on the study.

 

The research found that adolescents' total screen time per day had little impact on their mental health, both on weekends and weekdays.

 

It also found that the use of digital screens 2 hours, 1 hour, or 30 minutes before bedtime didn't have clear associations with decreases in adolescent well-being, even though this is often taken as a fact by media reports and public debates.
