Given the extended duration of future missions and the isolated, extreme and confined environments, there is the possibility that behavioral conditions and mental disorders (DSM-IV-TR) will develop. The overarching goal of this project is to deliver an Individualized Behavioral Health Monitoring Tool that unobtrusively integrates all available behavioral measures collected during a mission to provide a dashboard of behavioral health indicators. These indicators will be placed within the context of quantitatively-tracked mission stressors to provide meaningful feedback allowing behavioral issues to be detected and mitigated at an early stage. The result of this project will be a system prototype that can be deployed in space analog environments (e.g., Mars 520 study, Antarctica) for validation testing and ultimately deployed in long-duration space exploration missions. The critical need for an Individualized Behavioral Health Monitoring Tool has been identified as a priority outlined in the BHP Integrated Research Plan (July 2009) gap BMED3. Phase II will achieve: (1) an Individualized Behavioral Health Monitor software interface; (2) a data integration system; (3) a trend and change detection algorithm; and (4) a countermeasure selection aid. The Technology Readiness Level at the end of Phase II will be TRL 6.
