StudentLife: Using Smartphones to Assess Mental Health and Academic Performance of College Students
Much of the stress and strain of student life remains hidden. The StudentLife continuous sensing app assesses the day-to-day and week-by-week impact of workload on stress, sleep, activity, mood, sociability, mental health and academic performance of a single class of 48 students across a 10-week using Android phones. Results from the StudentLife study show a number of significant correlations between the automatic objective sensor data from smartphones and mental health and educational outcomes of the student body. We identify a Dartmouth term lifecycle in the data that shows students start the term with high positive affect and conversation levels, low stress, and healthy sleep and daily activity patterns. As the term progresses and the workload increases, stress appreciably rises while positive affect, sleep, conversation and activity drops off. We show how passive sensing data from phones can infer studying and partying behavior across the term. Finally, we show how a smartphone can automatically predict student GPA.
Andrew T. Campbell is a professor of computer science at Dartmouth College, where he leads the smartphone sensing group. His group developed a number of early sensing applications for smartphones and is currently focused on turning the everyday smartphone into a cognitive phone. Andrew received his Ph.D. in computer science (1996) from Lancaster University, England and the NSF Career Award (1999) for his research in programmable wireless networks. Before joining Dartmouth, he was a tenured associate professor of electrical engineering at Columbia University (1996-2005). Prior to that, he spent ten years in the software industry in the US and Europe leading the development of operating systems and wireless networks. Andrew has been a technical program chair of a number of conferences in his area including ACM MobiCom, ACM MobiHoc and ACM SenSys; also, he co-chaired the NSF sponsored workshop on pervasive computing at scale (2011) and the recent NSF workshop on student health (2015). Andrew is currently a visiting faculty at CMU in Rwanda and spent his sabbatical year (2003-2004) at the computer laboratory, Cambridge University, as an UK EPSRC visiting fellow, and fall 2009 as a visiting professor at the University of Salamanca, Spain.
