Which PTSD Treatments Have Been Studied?
How Are Treatments for PTSD Tested?
We learn which treatments are effective for helping with PTSD by using scientific methods. The most rigorous way to determine the effectiveness of a treatment is to use a randomized controlled trial (RCT) design, in which participants are assigned randomly—or by chance—to one treatment or another. Random assignment improves our confidence that changes in PTSD symptoms are due to the treatments themselves rather than some other cause.
Which treatments are in the PTSD-Repository?
The PTSD-Repository includes RCTs that fall into 7 general categories (labeled in the datasets as study class). Psychotherapy is talk therapy with a licensed provider. Pharmacotherapy uses medications to treat symptoms. Complementary and integrative health (CIH) treatments represent a wide category of approaches that are considered to be outside the standard of current practice of Western medicine. Collaborative care treatments are those in which integrated medical and mental health treatment is delivered in primary care, often by nurse managers. Nonpharmacologic biological treatments use a medical device or medical procedure of some kind. Nonpharmacologic cognitive treatments teach cognitive skills to improve attention. There is also an Other treatments category for studies that do not fit into the 6 main categories. We also identify control conditions--comparison conditions such as a placebo medication, waitlist, inactive (sham) device, and treatment as usual (i.e., when treatment as usual cannot be clearly defined as another specific treatment).
How is treatment type coded?
First, studies were broken down by study arm (i.e., condition), each coded into one of the categories described to the left. Three treatment types have sub-codes. Psychotherapy is coded as trauma-focused or non-trauma-focused. Pharmacotherapy is coded with several different sub-codes such as antianxiety, antidepressant, etc. CIH is coded as relaxation, meditation, physical activity and recreational therapy, yoga, and others. Then the overall study was classified according to which active treatment(s) were being tested (i.e., study class). For example, a study comparing a psychotherapy to a waitlist condition was coded as having two arms, Psychotherapy and Control, and then the study class was coded as Psychotherapy. The arms and overall study could be “mixed,” meaning that more than one active treatment type is represented. For example, a study might compare medication and psychotherapy, combined within the same arm, to just the psychotherapy. The medication-psychotherapy arm and study would be coded as “mixed-psychotherapy and pharmacotherapy.” For more information, see the How the Data Were Organized story.
The 389 RCTs in the PTSD-Repository were published between 1988 and May, 2020.Almost half of these studies are psychotherapy trials (n = 192, 49%).There are fewer, but still many, pharmacotherapy studies (n = 88, 23%).Over time, more studies have examined CIH interventions and combination treatments.
Psychotherapies for PTSD
The most effective treatments for PTSD are trauma-focused psychotherapies, including Prolonged Exposure (PE), Cognitive Processing Therapy (CPT), and Eye Movement Desensitization and Reprocessing (EMDR).
"Trauma-focused" means that the treatment focuses on the memory of the traumatic event or its meaning.
To the right, you can see that the majority of treatment arms in psychotherapy studies in the PTSD-Repository are trauma-focused. By clicking on the “TF" (i.e., trauma-focused) bar, you can dig deeper to see the specific trauma-focused psychotherapies studied; PE, EMDR, CBT, CPT, and Narrative Exposure Therapy (NET) have been studied most frequently.
You can find more information about these treatments in the Trauma-focused Psychotherapy for PTSD data story in the PTSD-Repository and on the National Center for PTSD website: PTSD Treatment Basics.
Medications for PTSD
Most studies of medications for PTSD have examined antidepressants, specifically selective serotonin reuptake inhibitors (SSRI).
Three of the four recommended medications for PTSD are SSRIs (sertraline, paroxetine, and fluoxetine). Venlafaxine, a selective norepinephrine reuptake inhibitor (SNRI), is also recommended. See the National Center for PTSD website for more information about Medications for PTSD.
By clicking on each slice, you can dig deeper to see the specific medications examined in studies within the PTSD-Repository. For more information about the pharmacotherapy studies in the PTSD-Repository, see our Medications for PTSD data story.
The PTSD Treatment Decision Aid can help you decide which treatment is right for you.
This free online tool helps you see how different treatments measure up against one another. It also gives you tips on how to work with your provider to decide on a treatment. You can watch videos of providers explaining how treatments work, build a chart to compare the treatments you like the most, and print a personalized summary.

Complementary and Integrative Health (CIH) Interventions
Complementary and integrative health (CIH) interventions, also called complementary and alternative medicine (CAM), include treatments not considered to be standard in the current practice of Western medicine. They are “complementary” in that they are often used in combination with conventional approaches.
The most frequently studied CIH interventions are relaxation, meditation (including mindfulness), and physical activity and recreational therapies. The PTSD-Repository has 61 CIH treatments arms, which also include studies of yoga, acupuncture, creative therapies like art and music therapy, and others. Some people experience benefits from these approaches, but published research does not indicate that using CIH interventions alone improve PTSD.
For more information, see Complementary and Alternative Medicine for PTSD on the National Center for PTSD website.
Other Treatments in the PTSD-Repository
Collaborative care treatments are those in which integrated medical and mental health treatment is delivered in a primary care setting, often by nurse managers. There are 6 studies of collaborative care for PTSD in the PTSD-Repository. As described in the 2017 VA/DOD Clinical Practice Guideline for PTSD, these studies provided evidence of increased PTSD treatment compliance and patient satisfaction, with the benefits of collaborative care outweighing the risks.
Nonpharmacologic biological treatments use a medical device or procedure of some kind to treat PTSD. The most extensively studied treatment of this type is repetitive transcranial magnetic stimulation (TMS). Seventeen treatment arms in the PTSD-Repository include active TMS, all of which are stand-alone TMS except one study of TMS combined with CPT. The specific TMS protocols vary from study to study. Other treatments include stellate ganglion block, transcranial direct current stimulation, and others.
Nonpharmacologic cognitive treatments teach cognitive skills to improve attention. The treatments typically involve tasks completed on a computer that are intended to help patients change how they pay attention. For example, attention bias modification training was designed to teach patients to orient attention away from threatening images. There are only 6 studies of this type. To date, these treatments are not typically used outside of research settings.
