What You Need to Know Before You Apply

What is the purpose of this trial?

The overall goal of this randomized controlled trial with partial crossover is to compare the effectiveness of 1-week virtual massed Cognitive Processing Therapy (CPT) to 5-day virtual relaxation training (RT) with regard to their ability to reduce posttraumatic stress disorder (PTSD) symptoms. Specifically, this study is designed to 1) examine changes in PTSD symptoms during and following the respective intervention, and 2) explore possible psychological treatment mechanisms, including cognitive control, inhibition, self-efficacy, and memory, and 3) examine possible moderators of treatment success (e.g. neuropsychological factors).

Do I have to stop taking my current medications for the trial?

The trial does not specify if you need to stop taking your current medications, but you must have been on a stable dose of any psychotropic medication for at least one month before starting the trial.

Is Cognitive Processing Therapy (CPT) safe for humans?

Cognitive Processing Therapy (CPT) is widely regarded as a safe treatment for post-traumatic stress disorder (PTSD) and has been used effectively in various settings, including among military personnel and sexual assault survivors, without significant safety concerns reported.12345

How is Cognitive Processing Therapy (CPT) different from other treatments for PTSD?

Cognitive Processing Therapy (CPT) is unique because it combines education, exposure, and cognitive components to help individuals process and challenge their beliefs about traumatic events, which is different from other therapies that may focus solely on exposure or medication. It is often delivered in a group format, making it efficient for treating multiple individuals simultaneously, and has been shown to be effective for various populations, including military personnel and sexual assault survivors.23567

What data supports the effectiveness of the treatment Cognitive Processing Therapy (CPT) for PTSD?

Cognitive Processing Therapy (CPT) is an evidence-based treatment that has been shown to effectively reduce PTSD symptoms in various settings, including among military personnel and veterans. Studies indicate that CPT can lead to significant improvements in PTSD symptoms, with many patients experiencing a reduction in symptoms after completing the therapy.12589

Published Research Related to This Trial

In a study of 268 active-duty servicemembers, individual cognitive processing therapy (CPT) was found to be more effective than group CPT in reducing PTSD severity, with significant improvements noted immediately after treatment.
Both individual and group formats of CPT led to reductions in depression and suicidal ideation, but about 50% of participants still experienced PTSD symptoms after treatment, highlighting the need for improved or new therapeutic options in this population.
Effect of Group vs Individual Cognitive Processing Therapy in Active-Duty Military Seeking Treatment for Posttraumatic Stress Disorder: A Randomized Clinical Trial.Resick, PA., Wachen, JS., Dondanville, KA., et al.[2022]
Cognitive processing therapy (CPT) was found to be effective for treating PTSD in a diverse group of 259 veterans, with 76.1% of those who completed the therapy reporting significant improvement in their symptoms.
The study indicated that while CPT is broadly applicable across different demographics and trauma types, individual characteristics largely influenced treatment outcomes, and no specific predictors were identified for varying responses to the therapy.
Predicting response to cognitive processing therapy: Does trauma history matter?Roberge, EM., Weinstein, HR., Bryan, CJ.[2022]
Cognitive Processing Therapy (CPT) effectively reduced PTSD symptoms in a study of 18 patients, with 15 participants showing statistically significant improvements in their symptom scores.
The study highlights the successful adaptation of the CPT protocol to address specific barriers faced by trauma survivors, demonstrating its potential for broader implementation in similar treatment settings.
