Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Written Exposure Therapy

Group Type EXPERIMENTAL

Written Exposure Therapy (WISE)

Intervention Type BEHAVIORAL

WISE consists of five weekly sessions. At session one, the therapist will provide psychoeducation about PTSD, rationale for the proposed intervention, and then instructions for writing about their traumatic experience during each session. Psychoeducation and treatment rationale are scripted to ensure consistency. The participant will be instructed to write about the same trauma memory (their recent MVC) during each session. They will be asked to look back at the event and write for 30 minutes about the details of the event including what they saw, heard, felt, smelled, etc. without regard for spelling or grammar. The participant will self-report SUDs levels to the therapist at the beginning and end of each session. After 30 minutes, the therapist will ask the participant to stop writing, review the experience of writing and discuss as needed, and conclude the session. Therapists will collect the written narrative described above.

Non-emotional Writing

Group Type PLACEBO_COMPARATOR

Non-emotional Writing

Intervention Type BEHAVIORAL

Following randomization, the first session for the control writing condition will be conducted as follows, which is detailed in a structured manual for therapists. The therapist will read instructions for writing about non-emotional topics. The participant will be instructed to describe what they did yesterday from the time they woke up until the time they went to bed, as objectively as possible, without regard for spelling or grammar. The therapist will then leave the participant with a written version of the instructions for 30 minutes while the participant writes. As discussed, the participant will self-report Subjective Unites of Distress Scale (SUDS) levels to the therapist at the beginning and end of each session. After 30 minutes, the therapist will ask the participant to stop writing, review the experience of writing and discuss as needed, and conclude the session. Therapists will collect the written narrative described above.
