PTSD Repository
For Providers


The PTSD Repository is a useful tool for staying up-to-date with PTSD clinical trials research, to inform your work and to support patient education. Currently, the PTSD Repository includes 550 clinical trials published between January 1, 1988 and April 1, 2024.

Finding relevant clinical trials

Use the table below to identify all randomized controlled trials (RCTs) in the PTSD Repository of a specific treatment. The “Filter” below will populate treatments by how common they are or you can type a treatment name in the search to find your preference(s).
When you choose a treatment name, the table displays study arms from trials that include your selection. Some studies have more than one arm with your chosen treatment. For example, if you chose "Prolonged Exposure" for the Standardized Treatment Name, a Study ID would be repeated with a different arm label (e.g., acierno2017_A is Prolonged Exposure in person and acierno2017_B is Prolonged Exposure via video).

To learn more about PTSD outcomes in the studies from the table above, you can find standardized effect sizes in datasets on the PTSD Repository. Within group effect sizes are an analog of Cohen’s d estimate of pre-post change for a specific treatment. Between group effect sizes are Hedge’s g estimates of the difference in change between the active treatment and the comparison condition.
