摘要

Our open-access mobile-health-application, BiAffect, leverages Apple’s Research-Kit and a custom-built virtual keyboard to collect typing kinematics metadata passively and unobtrusively while preserving content anonymity. In this open-science study on mood, participants were prompted to report depression severity using the Patient Health Questionnaire (PHQ-8; omitting suicidality question).
