• Technologies for Assessing Behavioral and Cognitive Markers of Suicide Risk

    DOD Proposal # : PT140188 Title : Technologies for Assessing Behavioral and Cognitive Markers of Suicide Risk In the current project, we propose innovative methods for investigating the causes and development of suicide risk among members of the National Guard and their family members by examining the behavioral, cognitive, and emotional dynamics that occur within military couples, thereby addressing these three knowledge gaps in suicide prevention. We will employ novel Behavioral Signal Processing technologies that allow scaling up and systematizing data collections thus enabling expanded observational windows through in-situ observations of both spouses, and expansion of the pertinent information available. Our proposed research strategy is designed to optimize our ability to achieve this scientific aim as well as to lay the foundation for an internet-based platform that can be used by concerned spouses to assess suicide risk from home on an as-needed basis. To achieve these objectives, we will partner with the National Center for Veterans Studies, a non-profit research and advocacy organization with strong ties to the local military and veteran communities. Dr. Georgiou leads this effort along with Drs. Baucom, Univ. of Utah and Narayanan.
