Ambulatory physiological assessment of posttraumatic stress disorder: Integrating passive sensing with ecological momentary assessment to measure trauma reactivity.

ABSTRACT: The development of wearable technology affords objective measurement of physiological states outside the laboratory. We used ambulatory physiological assessment to measure overall arousal and reactivity to trauma reminders, a hallmark symptom of posttraumatic stress disorder (PTSD). Ambulatory assessment improves upon laboratory-based tests by measuring actual trauma reminders as they occur in everyday life. In this study, we recruited a mixed-trauma sample of 80 participants (39 diagnosed with PTSD) who completed 3 days of ambulatory physiological assessment time-synced with self-reported ecological momentary assessments of trauma reminders and contextual factors. We assessed heart rate (interbeat interval [IBI]) as a nonspecific marker of overall physiological arousal, skin conductance a
