The debate on how social media use (SMU) influences adolescent well-being is mostly based on self-reports of SMU. By collecting data and screenshots donated from 374 Swiss adolescents (Meanage = 15.71; SDage = 0.82) over 2 weeks, we created "Appnomes"-app-specific usage metrics on screentime, number of activations, and number of notifications per participant per day derived, and associated them with daily hedonic and eudaimonic well-being. Longer TikTok time predicted lower eudaimonic well-being (β = - 0.08) daily but higher positive emotions (β = 0.06) the next day; longer use of WhatsApp predicted negative emotions (β = 0.06) while more screen activations for WhatsApp predicted greater feelings of connection (β = 0.08). Instagram notification was positively related to increased feeling of focused (β = 0.06) the next day. YouTube screen unlocks predicted more feeling of meaning (β = 0.07) the next day. More Snapchat screentime predicted less relaxed, less competent, and less positive emotions (with - 0.07 < β < - 0.06). Results pointed towards minimal or no effects, challenging the moral panic on the detrimental impact of SMU on teen well-being.
关于社交媒体使用（SMU）如何影响青少年幸福感的辩论大多基于对SMU的自我报告。通过收集374名瑞士青少年（平均年龄=15.71；标准差年龄=0.82）在两周内捐赠的数据和截图，我们创建了“应用名称”——关于屏幕使用时间、激活次数和每位参与者每天通知次数的特定应用使用指标，并将它们与日常享乐幸福感和实现幸福感相关联。TikTok使用时间越长，预测每日的实现幸福感越低（β=-0.08），但第二天的积极情绪越高（β=0.06）；使用WhatsApp的时间越长，预测消极情绪越高（β=0.06），而WhatsApp的屏幕激活次数越多，预测联系感越强（β=0.08）。Instagram通知与第二天注意力增强的感觉呈正相关（β=0.06）。YouTube屏幕解锁次数预测第二天更有意义感（β=0.07）。更多的Snapchat屏幕使用时间预测更不放松、能力更弱和积极情绪更少（-0.07<β<-0.06）。结果表明影响极小或没有影响，对关于SMU对青少年幸福感有不利影响的道德恐慌提出了挑战。
