The DARPA Detection and Computational Analysis of Psychological Signals (DCAPS) program provided initial funding for the Durkheim Project. While DCAPS as a whole addressed PTSD, the Durkheim Project sought to predict military and veteran suicide risk. We developed a clinician's dashboard, which presents suicide risk predictions for the clinician's patients based on analysis of: a) free text portions of VA medical records and, b) opt-in social media postings. Dartmouth's Committee for the Protection of Human Subjects approved our protocol to conduct a Veterans Affairs (VA) medical records study with the White River Junction, Vermont, VA Medical Center. A second protocol has been approved to study opt-in Facebook postings from active duty military personnel and veterans. We have built the software infrastructure to collect these opt-in postings in collaboration with Facebook. A third protocol is currently being developed to support intervention, when high suicide risk is predicted. This talk will describe the Durkheim Project, focusing on privacy issues related to using opt-in social media postings.
