PTSD Psychotherapy Study

PTSD Psychotherapy Study: Biomarker Establishment for Superior Treatment of PTSD (B.E.S.T.) 

The mission of the B.E.S.T. study is to use multimodal neuroimaging and behavioral tasks to identify biomarkers predicting which Veterans will respond to evidence-based treatments for PTSD. Our ultimate goal is to improve diagnosis and treatment for Veterans with PTSD.

The Etkin Lab is dedicated to discovering effective and personalized treatments for PTSD and other mental health disorders and lessening the burden of these conditions on service members, veterans, and their families. We aim to use cutting-edge brain science to improve diagnosis and treatment for veterans with PTS.

What Does the Study Involve?
Veterans visit Stanford/Palo Alto VA for approximately 2-3 days for a baseline assessment and 2-3 visits for a post-treatment evaluation. They also complete an assessment over the phone midway through treatment and six months after the end of treatment. In addition, Veterans complete questionnaires at home in between their baseline and post-treatment assessments.

Study Procedures:

  • Clinical Psychological Assessments (Interview)

  • Genetic Blood test

  • Computer-based tests

  • Electroencephalography (EEG)

  • Magnetic Resonance Imaging (MRI)

  • Transcranial Magnetic Stimulation (TMS)

Study Criteria
We are recruiting Veterans who are diagnosed with PTSD and who are planning to begin treatment at any VA medical center site in the United States.

Participants are compensated up to $975 for participating in this study.
