Query: Posttraumatic Stress Disorder Hyperarousal Event Detection Using
  Smartwatch Physiological and Activity Data   Posttraumatic Stress Disorder (PTSD) is a psychiatric condition affecting
nearly a quarter of the United States war veterans who return from war zones.
Treatment for PTSD typically consists of a combination of in-session therapy
and medication. However; patients often experience their most severe PTSD
symptoms outside of therapy sessions. Mobile health applications may address
this gap, but their effectiveness is limited by the current gap in continuous
monitoring and detection capabilities enabling timely intervention. The goal of
this article is to develop a novel method to detect hyperarousal events using
physiological and activity-based machine learning algorithms. Physiological
data including heart rate and body acceleration as well as self-reported
hyperarousal events were collected using a tool developed for commercial
off-the-shelf wearable devices from 99 United States veterans diagnosed with
PTSD over several days. The data were used to develop four machine learning
algorithms: Random Forest, Support Vector Machine, Logistic Regression and
XGBoost. The XGBoost model had the best performance in detecting onset of PTSD
symptoms with over 83% accuracy and an AUC of 0.70. Post-hoc SHapley Additive
exPlanations (SHAP) additive explanation analysis showed that algorithm
predictions were correlated with average heart rate, minimum heart rate and
average body acceleration. Findings show promise in detecting onset of PTSD
symptoms which could be the basis for developing remote and continuous
monitoring systems for PTSD. Such systems may address a vital gap in
just-in-time interventions for PTSD self-management outside of scheduled
clinical appointments.
