Injured Trauma Survivor Screen (ITSS)

The Injured Trauma Survivor Screen (ITSS; pronounced “its”) is a brief, nine-item questionnaire that was created for, and normed on, patients admitted to the Trauma Service of a Level 1 Trauma Center following an acute injury event.  Developing an effective means to screen for Posttraumatic Stress Disorder (PTSD) and Major Depressive Episode (MDE) in this population has been highlighted as a major need by the American College of Surgeons - Committee on Trauma. To address this critical gap, our group created the ITSS which was developed after a comprehensive literature review focused on prospective longitudinal studies that identified various robust risk predictors (i.e., perceived threat to life).1  We then used stepwise logistic regression to identify the strongest items among these highly predictive risk factors.  The ITSS has yielded a sensitivity (true positive rate) of 75% for the development of PTSD and MDE at one-month post injury, and ~85% for PTSD and ~72% for MDE at six-months post-injury.2,3

Multi-institutional trial of the Injured Trauma Survivor Screen (MITSS) standardization training. Dr. Tim Geier is the lead for the standardization training and is available via email at or via telephone at 414-955-1700.  Once a member of the MITSS trial, your team will be granted access to a shared Box folder containing all of the necessary measures, protocols, forms, and additional standardization materials. You may begin the standardization training below by requesting access to the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) training presented by the Department of Veterans Affairs, Employee Education System, and the National Center for Posttraumatic Stress Disorder
