This paper presents results from the Smart Healthy Campus 2.0 study/smartphone app, developed and used to collect mental health-related lifestyle data from 86 Canadian undergraduates January-August 2021. Objectives of the study were to 1) address the absence of longitudinal mental health overview and lifestyle-related data from Canadian undergraduate students, and 2) to identify associations between these self-reported mental health overviews (questionnaires) and lifestyle-related measures (from smartphone digital measures). This was a longitudinal repeat measures study conducted over 40 weeks. A 9-item mental health questionnaire was accessible once daily in the app. Two variants of this mental health questionnaire existed; the first was a weekly variant, available each Monday or until a participant responded during the week. The second was a daily variant available after the weekly variant. 6518 digital measure samples and 1722 questionnaire responses were collected. Mixed models were fit for responses to the two questionnaire variants and 12 phone digital measures (e.g. GPS, step counts). The daily questionnaire had positive associations with floors walked, installed apps, and campus proximity, while having negative associations with uptime, and daily calendar events. Daily depression had a positive association with uptime. Daily resilience appeared to have a slight positive association with campus proximity. The weekly questionnaire variant had positive associations with device idling and installed apps, and negative associations with floors walked, calendar events, and campus proximity. Physical activity, weekly, had a negative association with uptime, and a positive association with calendar events and device idling. These lifestyle indicators that associated with student mental health during the COVID-19 pandemic suggest directions for new mental health-related interventions (digital or otherwise) and further efforts in mental health surveillance under comparable circumstances.
本文展示了“智慧健康校园2.0”研究/智能手机应用程序的结果，该程序于2021年1月至8月开发并用于收集86名加拿大本科生与心理健康相关的生活方式数据。该研究的目的是：1）解决加拿大本科生缺乏纵向心理健康概况和与生活方式相关数据的问题；2）确定这些自我报告的心理健康概况（问卷）与生活方式相关指标（来自智能手机数字测量）之间的关联。这是一项为期40周的纵向重复测量研究。应用程序中每天可访问一次包含9个条目的心理健康问卷。该心理健康问卷有两个版本；第一个是每周版本，每周一可用，或者直到参与者在当周做出回应。第二个是每周版本之后可用的每日版本。共收集到6518个数字测量样本和1722份问卷回复。对两个问卷版本的回复以及12项手机数字测量指标（如全球定位系统、步数）进行了混合模型拟合。每日问卷与步行楼层数、安装的应用程序和校园距离呈正相关，与开机时间和每日日历事件呈负相关。每日抑郁情绪与开机时间呈正相关。每日心理韧性似乎与校园距离呈轻微正相关。每周问卷版本与设备闲置和安装的应用程序呈正相关，与步行楼层数、日历事件和校园距离呈负相关。每周的体育活动与开机时间呈负相关，与日历事件和设备闲置呈正相关。这些在新冠疫情期间与学生心理健康相关的生活方式指标为新的心理健康相关干预措施（数字或其他方式）以及在类似情况下进一步开展心理健康监测工作提供了方向。
