Weill Cornell Medical College researchers seek participants who experienced a traumatic event for a one year post traumatic stress disorder (PTSD) study. Participants will be assessed for PTSD and related symptomatology and followed up for 1 year. Participants will also contribute saliva sample for genetic biomarkers analysis.

This study aims to test genetic predictors of PTSD following trauma and to understand the longitudinal course of PTSD in trauma survivors, including psychiatric symptoms, impairment, and reaction to reintegration to daily life. All assessments are free of cost and confidential.
