Clinical Trial Intelligent Biometrics for PTSD - Clinical Trial

Posttraumatic stress disorder (PTSD) is a chronic and debilitating psychiatric condition. Prolonged Exposure (PE) therapy is a highly effective, evidence-based treatment for PTSD; however, dropout rates are high and approximately one-third of patients who complete treatment remain symptomatic. The proposed study will employ a randomized clinical trial (N=40 treatment-seeking veterans with current PTSD) to evaluate the acceptability, feasibility and preliminary efficacy of a technological enhancement (IB-PE), and investigate predictors of outcome by accomplishing the following milestones: (1a) Evaluate ability of IB-PE (therapist guided vs. record only) in reducing PTSD severity from baseline to end of treatment; and (2b) Use a variety of in vivo exposures (IVEs) to identify biometric and behavioral indicators (high heart rate, skin conductance) with high predictive value of treatment response. We will use a technology system of discrete wearables (camera, microphone) to allow therapists to accompany participants during IVEs. The system will pair with a cellular application and record information such as heart rate and skin conductance. This system will also allow the participant to communicate with the study therapist during the guided in vivo exercises.
