Study summary

It is urgent to make evidence-based treatments (EBTs) for military personnel readily accessible in order to meet the growing demand for effective and efficient treatment for posttraumatic stress disorder (PTSD) in a timely manner. Effective EBTs for PTSD are available, but barriers to accessing care can deter military personnel from receiving treatment. Web-treatments represent an innovative way to overcome these barriers. The efficacy of previously developed web-treatments for PTSD appear promising, however, they are not based on treatment protocols with strong empirical support for their efficacy. No study to date has examined web-treatment of PTSD using a well-established treatment program.

The purpose of this open trial is to examine the efficacy of 10 sessions of a web-version of Prolonged Exposure (PE), "Web-PE," delivered over 8-weeks in 40 active-duty military personnel and veterans with PTSD who deployed post 9-11. Up to 60 individuals will be consented to obtain data from 40 for analysis. Participants will be assessed at pre-treatment and 1- and 3-months after treatment completion.

What researchers measure

Primary outcomes

  1. PTSD CheckList-5 (PCL-5)

    A 20-item self-report measure of PTSD symptoms as defined by the DSM-5. Higher scores indicate greater PTSD symptom severity.

    Time frame: Change from baseline to 1-month follow-up (post-treatment)

Secondary outcomes

  1. Patient Health Questionnaire-9 (PHQ-9)

    A 9-item measure of the severity of depressive symptoms. Higher scores indicated greater depressive symptom severity.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2018 to primary completion in Mar 2019, 13 months.

Of 1,064 non-industry interventional studies with no phase under Stress Disorders, Post-Traumatic, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 53. This study's 13 months is below that.

Counting every sponsor, half of 1,092 studies reached it within 34 months; a quarter within 17 and three quarters within 53.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 19, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
