Research on Anxiety and Depression: Computer Assisted Therapy (RADCAT)

About the RADCAT Study

Adjunct to the RAD Project

  • The purpose of this study is to examine how online self-guided programs can improve mood and anxiety symptoms. 
  • These programs use exercises from Cognitive-Behavioral Therapy, which is an evidence-based treatment for depressive and anxiety disorders. 
  • We are hoping to figure out who is best suited for this type of online self-guided format and what kinds of symptoms improve the most.
  • We are grateful to The One Mind Institute, a non-profit organization devoted to funding cures for brain illnesses, who is providing financial support for the study. 

RADCAT Study Participation Details

The RADCAT study is for participants who have completed at least the RAD Project Session 1.  

  • The RADCAT study involves an online program developed to help with anxiety and depression symptoms, and answering weekly online surveys about your symptoms and your usage of the online program (this is all done from home). The study lasts 18 weeks, and participants will be compensated $75 - $100, as well as given free access to 6 different programs developed to help with anxiety and depression symptoms.  For more details, please contact us! 

Location:   The study not does involve any visits to Stanford - everything is done by phone or internet.

When:   After RAD Session 1

Duration:  18 weeks  


  • One (1) baseline assessment that is about 2 hours long;
  • 5-minutes of questionnaires every 1-2 weeks;
  • 30-minutes of questionnaires at the end of the study. 

Compensation:   $75 - $100 and free access to 6 different programs developed to help with anxiety and depression symptoms

MRI is a safe, painless, and non-invasive scan that uses magnets to display a detailed view of the brain's anatomy. No x-rays or radioactive material are used. Memory foam mattresses and other equipment, such as blankets, pillows, and sheets, are provided to ensure that participants are comfortable.

The MRI tube is open on both ends. You would be in the tube about until your knees (your knees down to your feet would be out of the tube). We would be communicating with you throughout the scan.
