The primary objectives of this proposal are to develop objective pre-deployment predictors of PTSD and test two pre-deployment resiliency interventions. Objective predictors include 1 physiologic reactivity to combat-related virtual reality environments and white noise startle and 2 cognitive bias assessment. We also will test two pre-deployment resiliency interventions 1 video game-based heart rate variability biofeedback training and 2 computerized cognitive bias training. Objective assessment and training measures are more reliably measured and could be early indicators of resiliencevulnerability. Study Design We will collect pre-deployment physiologic reactivity and cognitive bias data from Army National Guard andor Reserve members within 12 months of OIFOEF deployment. We plan to consent up to 600 soldiers in order to complete 500 pre-deployment assessments. Subjects will be randomized to one of three groups heart rate variability biofeedback training, cognitive bias training, or no additional training. Follow-up data will be collected at 3- and 12- months post- deployment. Major Findings There are no findings to report at this time. Project Status Pre-deployment baseline assessments are completed and the data is being prepared for analysis. Potential Impact The products from this study will include an objective model for PTSD risk assessment and evidence to support specific pre-deployment PSTD resiliency training.
