Mental Health and Behavior of College Students During the Early Phases of the COVID-19 Pandemic: Longitudinal Smartphone and Ecological Momentary Assessment Study.
Jeremy F. Huckins,Alex W. daSilva,Weichen Wang,Elin Hedlund,Courtney Rogers,Subigya Nepal,Jialing Wu,Mikio Obuchi,Eilis I Murphy,Meghan L. Meyer,Dylan D. Wagner,Paul E. Holtzheimer,Andrew T. Campbell +12 more
TL;DR: Compared with prior academic terms, individuals in the Winter 2020 term were more sedentary, anxious, and depressed, and a wide variety of behaviors, including increased phone usage, decreased physical activity, and fewer locations visited, were associated with fluctuations in COVID-19 news reporting.
Journal ArticleDOI
Tracking Depression Dynamics in College Students Using Mobile Phone and Wearable Sensing
Rui Wang,Weichen Wang,Alex W. daSilva,Jeremy F. Huckins,William M. Kelley,Todd F. Heatherton,Andrew T. Campbell +6 more
TL;DR: A new approach to predicting depression using passive sensing data from students' smartphones and wearables is proposed and it is shown that symptom features derived from phone and wearable sensors can predict whether or not a student is depressed on a week by week basis.
Journal ArticleDOI
Fusing Mobile Phone Sensing and Brain Imaging to Assess Depression in College Students.
Jeremy F. Huckins,Alex W. daSilva,Rui Wang,Weichen Wang,Elin Hedlund,Eilis I Murphy,Richard B. Lopez,Courtney Rogers,Paul E. Holtzheimer,William M. Kelley,Todd F. Heatherton,Dylan D. Wagner,James V. Haxby,Andrew T. Campbell +13 more
TL;DR: The data and analyses presented here provide relatively simplistic preliminary analyses which replicate and provide an initial step in combining functional brain activity and smartphone usage patterns to better understand issues related to mental health.
Journal ArticleDOI
Mental Health and Behavior of College Students During the COVID-19 Pandemic: Longitudinal Mobile Smartphone and Ecological Momentary Assessment Study, Part II.
Dante L Mack,Alex W. daSilva,Courtney Rogers,Elin Hedlund,Eilis I Murphy,Vlado Vojdanovski,Jane Plomp,Weichen Wang,Subigya Nepal,Paul E. Holtzheimer,Dylan D. Wagner,Nicholas C. Jacobson,Meghan L. Meyer,Andrew T. Campbell,Jeremy F. Huckins +14 more
TL;DR: In this paper, the authors studied the behavioral and mental health impacts associated with the COVID-19 pandemic, measured by interest across the United States in the search terms coronavirus and COVID fatigue.
Journal ArticleDOI
Correlates of Stress in the College Environment Uncovered by the Application of Penalized Generalized Estimating Equations to Mobile Sensing Data
TL;DR: In this paper, the authors use passive sensing data collected via mobile phones to obtain a rich and potentially less-biased source of data that can be used to help better understand stressors in the college experience.
