Brief Summary

PTSD is characterized by physiological changes, some of which are thought to be chronic, while others are observed in response to stressogenic stimuli. Prolonged Exposure (PE) therapy is a widely used protocol considered highly affective among individuals diagnosed with PTSD. The current study is a non-interventional observational study, aimed at measuring changes in the digital phenotype of participants with PTSD during and following PE therapy. Physiological data will be collected using wearable sensors during the sessions, and participants will be assessed using questionnaires and psychiatric assessments before and after the completion of their imaginal or writing based PE therapy (10-15 sessions).
