睡前看手机对身体不好吗?最新研究:影响不大

Unlike other studies, the Oxford research analyzed data from Ireland, the US, and the UK to support its conclusions. The researchers used a rigorous methodology to gather how much time an adolescent spends on screens per day, including both self-reported measures and time-use diaries.

与其它研究不同，牛津大学的研究分析了爱尔兰、美国和英国的数据来支持自己的结论。研究人员运用严谨的方法来收集青少年每天的屏幕使用时间，包括自我报告法和时长日记。

This is important as many studies are based solely on self-reported digital technology use, even though recent work found only one third of participants give accurate accounts of how much time they spend online when asked after the fact.

这些方法十分重要，因为许多研究仅基于自我报告数字科技的使用，但在近期研究中发现，仅有三分之一的参与者在回答问题时，给出了准确的上网时间。

The researchers were also able to create a comprehensive picture of teens' well-being, examining measures of psychosocial functioning, depression symptoms, self-esteem, and mood, with data provided by both young people and their caregivers.

根据年轻人和他们监护人提供的数据，研究人员可以描绘出青少年健康的全景图，研究测量心理社会功能、抑郁症状、自尊和情绪的方法。

Additionally, the final of the three studies conducted was preregistered, meaning that the researchers publicly documented the analyses they would run before they analyzed the data. This prevents hypothesizing after the results are known, a challenge for controversial research topics.
