Digital Phenotyping: A Novel Method to Predict Proximal Suicide Risk in Youth

Brief description of study

The goal of this study is to use keyboard metadata, a method of collecting data from written communications entered on iPhones, in addition to traditional assessments, to characterize the digital phenotype of suicide risk in adolescents. Adolescents with Bipolar Disorder or Major Depressive Disorder will download the BiAffect app from the App Store. During the 3-month period of the study, participants and their caregivers will complete questionnaires to assess other risk factors that are associated with suicide. Participants will also be prompted by the app to report on mood and suicidal thoughts and behaviors (STB), as well as complete active tasks twice a week. Participants will also be interviewed by phone monthly to assess the presence and timing of STB. Caregivers will be interviewed and complete questionnaires at baseline for another perspective on the presence and timing of STB in the adolescent participants.
