Study Information

TIES (Therapy Integrating Exposure and Stimulation) is a new study designed to help individuals with OCD who are looking for behavior therapy. The purpose is to investigate whether a type of noninvasive brain stimulation called tDCS, can help exposure and response prevention (ERP) work better.

What is exposure and response prevention (ERP)?

ERP is a type of behavior therapy considered most effective for treating OCD. Exposure involves gradually confronting feared situations and thoughts in order to get used to them. Response prevention involves learning to stop compulsions both during exposures and in daily life.

What is tDCS?

Transcranial direct current stimulation (tDCS), a form of brain stimulation, sends weak electrical currents through the brain. tDCS is noninvasive.


Individuals diagnosed with OCD may be eligible to participate if they are between the ages of 18 and 65, and are interested in behavior therapy for OCD. Interested individuals will be screened by study staff at Butler Hospital to determine whether they are eligible to participate. All study participants will receive: 

  • Comprehensive assessment of their symptoms.
  • An 11 session program that includes ERP with active or sham tDCS.
  • Compensation for time spent completing study assessments (up to $185 for full participation).
