Each year, more than 40 million Americans present to US emergency departments (EDs) for evaluation after traumatic stress exposure. The overwhelming majority of these individuals are discharged to home after evaluation. A wealth of data demonstrates that the development of adverse posttraumatic neuropsychiatric sequelae such as posttraumatic stress disorder (PTSD) are common in this population, and that individuals with a past history of traumatic stress exposure and/or posttraumatic stress symptoms, such as military veterans, are at increased risk. Unfortunately, no secondary preventive interventions are currently widely available that can prevent PTSD among those at high risk. This pilot Written Exposure Therapy to Improve Lives after Stress Exposure (WISE) trial will assess the ability of written exposure therapy to reduce the incidence and severity of PTSD after one of the most common traumatic stress exposures in industrialized countries, motor vehicle collision (MVC). Written exposure therapy is an evidence-based, low-cost intervention that has been demonstrated to be efficacious in treating chronic PTSD symptoms after a variety of traumatic stress exposures, including MVC. However, WISE has never been tested as a secondary preventive intervention. In addition, the efficacy of written exposure therapy when administered as a telehealth intervention has never been assessed, despite the fact that almost a quarter of US veterans live in rural communities that have greater barriers to obtaining in-person care. This WISE pilot trial will randomize 40 individuals who present to a study ED for care after MVC to five sessions of written exposure therapy vs. unemotional writing control. Both exposure and control interventions will be administered via telehealth (n=40), with 20 individuals receiving written exposure therapy and 20 receiving unemotional writing intervention. The same therapists will administer both interventions. Participants will be assessed via traditional self-report surveys. Results of this trial will demonstrate the feasibility and potential efficacy of WISE to reduce the development of PTSD after traumatic stress exposure and will provide the data necessary to design/support a large-scale trial.
The main objective of this study is to determine whether remote delivery of written exposure therapy after motor vehicle collision reduces incidence and severity of posttraumatic stress symptoms in high risk individuals. This randomized controlled trial is a pilot study to determine feasibility and potential efficacy. This data can be used to adequately power a larger randomized controlled trial.
