Stakeholders, such as college campus administrators and clinicians, are committed to alleviating students' mental health concerns and the campus' mental health climate, but they suffer from a lack of timely and actionable information. Research has revealed that student personal data, such as self-tracking and social media data, can provide in-situ insights about students' mental health states. However, how they can support stakeholders' goals remains unexplored. We examine the potential of user-centered technology in addressing this challenge. We interviewed campus administrators and clinicians to understand their needs and current practices. Then through a paper prototype, we gathered design suggestions for stakeholder-facing dashboards. We generated three design implications revealed through our studies: that social media can be a potentially useful resource for understanding student mental health albeit concerns of data reliability and interpretability; that the dashboards need to assuage stakeholders' concerns around bias and intelligibility of the visual presentations, which can become barriers to future adoption; and that ethical considerations, particularly securing privacy of student data, need to be salient in the design.
