抑郁症状在不同数字情境中的反映存在差异
Depressive symptoms are reflected differently across digital contexts
AI总结：
本研究通过分析1,146名德国成年人的移动和桌面网络使用数据，发现抑郁症状在不同设备与活动情境中的数字行为反映存在显著差异，强调需关注在线行为的具体内容与情境。
AI中文摘要：
随着日常生活越来越多地在线上进行，数字行为可能为了解抑郁症状如何在日常生活中得到反映提供了一个潜在窗口。然而，数字心理健康研究产生了不一致的发现。这些不一致可能部分反映了数字行为的测量方式：自我报告的使用情况、单一设备研究以及聚合屏幕时间可能掩盖了不同设备、活动和参与模式之间的差异。我们将抑郁症状的月度评估与来自德国1,146名成年人在六个月期间被动记录的移动端和桌面端网络痕迹相结合。我们考察了总体、认知情感和躯体抑郁症状如何在由设备和活动类型定义的数字情境中得到反映。关联在不同情境间差异显著。在移动端，更严重的症状与更多的夜间活动、更频繁地使用社交媒体、消息和娱乐应用以及更少但更长的会话相关。在桌面端，关联较少，且主要涉及对新闻、购物和成人内容参与的减少。移动端的关联主要出现在总体和认知情感症状中，而桌面端的关联集中于躯体症状。我们的研究结果表明，描述抑郁症状如何在数字行为中得到反映需要关注人们在线做什么以及在哪里做，而不仅仅是屏幕使用的时长。
英文摘要：
As more of everyday life takes place online, digital behavior may provide a potential window into how depressive symptoms are reflected in daily life. Yet digital mental health studies have produced mixed findings. These inconsistencies may partly reflect how digital behavior is measured: self reported use, single device studies, and aggregate screen time can obscure differences across devices, activities, and patterns of engagement. We combined monthly assessments of depressive symptoms with passively recorded mobile and desktop web traces from 1,146 adults in Germany over six months. We examined how general, cognitive-affective, and somatic depressive symptoms are reflected across digital contexts defined by device and activity type. Associations varied markedly across these contexts. On mobile, more severe symptoms were associated with more nighttime activity, greater use of social media, messaging, and entertainment, and fewer but longer sessions. On desktop, associations were fewer and largely involved reduced engagement with news, shopping, and adult content. Mobile associations primarily arose for general and cognitive-affective symptoms, whereas desktop associations were concentrated in somatic symptoms. Our findings suggest that characterizing how depressive symptoms are reflected in digital behavior requires attending to what people do online and where, not only how much screens are used.
