Interventions
BEHAVIORAL
Cognitive Processing Therapy
Regardless of which assignment, participants will receive 10 sessions of Cognitive Processing Therapy (CPT) delivered daily Monday through Friday over two consecutive weeks. In CPT treatment participants will complete symptom checklists and learn a variety of skills to help with symptoms of PTSD.
Primary outcome measures
PTSD Checklist for DSM-5 (PCL-5)
Time frame: From baseline to 12-months follow up
The PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (PCL-5) is a 20-item self-report measure used to assess PTSD symptom severity and monitor clinical change over time. Each item is rated on a 5-point scale (0 = Not at all to 4 = Extremely), yielding a total score ranging from 0 to 80, with higher scores indicating worse PTSD symptom severity.
Self-Injurious Thoughts and Behaviors Interview-Revised (SITBI-R)
Time frame: Baseline to 12 months posttreatment
The Self-Injurious Thoughts and Behaviors Interview-Revised (SITBI-R) is a structured clinical interview assessing the presence and characteristics of suicidal and nonsuicidal thoughts and behaviors. The SITBI-R does not produce a single total score; instead, each item is coded dichotomously as 0 = "No" or 1 = "Yes" to indicate the presence of a given thought or behavior. Higher item values indicate the presence of the self-injurious thought or behavior being assessed.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
