Description
Li Du and colleagues compared the mental health of Chinese teenagers learning online at home against peers back in school during the pandemic. Their 2026 survey covered 5,787 students in grades seven through twelve at fourteen Gansu schools across 2020 and 2021. Standard questionnaires measured mood, distress, and sleep. Scores were set against national norms and sorted by learning mode, sex, and stage.
Students showed more distress than national yardsticks on several fronts, and nearly a quarter carried moderate to severe depressive symptoms. Surprisingly, in-school students reported worse distress and depression than online learners at home. Sleep told a consistent story: teens who felt their sleep poor, took long to fall asleep, or slept fewer hours all fared worse mentally. Because the survey caught one moment, learning mode cannot be said to have caused the gaps. They suggest sleep coaching and calmer school climates as supports worth building either way.
