Mind Body Treatment for Irritable Bowel Syndrome (IBS)
Conducted by Kirsten Tillisch, MD

Men and women with Irritable Bowel Syndrome (IBS) may be eligible to participate in a research study conducted by Kirsten Tillisch, MD at the UCLA Gail and Gerald Oppenheimer Family Center for Neurobiology of Stress.

The purpose of this research is to use functional magnetic resonance imaging (fMRI) to identify diagnostic brain biomarkers of IBS and the effect of Mindfulness Based Stress reduction (MBSR) training on these markers and IBS symptoms.

You must be:

  • Between 18-50 years of age
  • Right-handed
  • No neurological or significant psychiatric history

If eligible you may earn up to $340 and receive an 8-weekMBSR training course at no charge.
Participation involves a screening, 2 MRI’s and attendancein the 8-week MBSR Training.

Men and Women with and without IBS Needed for a Study Exploring the Brain-Gut Connection
Conducted by Emeran Mayer, MD

Are You Interested in the Brain-Gut Connection? Help us explore this connection by participating in our study.

If you have Irritable Bowel Syndrome (IBS) or are a healthy adult you may be eligible.

If you are between the ages of 18 and 55, you may qualify to participate in a UCLA research study conducted by Dr. Emeran Mayer. The purpose of this study is to learn more about how IBS develops, which may lead to the development of diagnostic tests and treatments.

This study consists of 2-3 visits:

  • Baseline (clinical assessment, questionnaires, saliva, blood, stool and urine sample)
  • Brain MRI
  • DEXA scan and blood draw

Compensation is up to $150.

If interested, please call (310) 206-8545



Men and Women with and without IBS Needed for Hormone Challenge Study
Conducted by Lin Chang, MD

Do you suffer from Abdominal Pain and/or Discomfort, Constipation or Diarrhea? Have you ever been told you have Irritable Bowel Syndrome (IBS)? Or, are you a Healthy Adult?

If so, and you are between the ages of 18 and 55, you may qualify to participate in a UCLA research study conducted by Dr. Lin Chang. The purpose of this study is to compare certain components found in the saliva, blood, urine, and stool and responses to stressors between IBS patients and healthy adults.

Eligible participants will complete 3 visits where they will:

  • Undergo medical and psychological evaluation, fill out questionnaires, and provide saliva, blood, urine, and stool samples
  • Complete two hormone challenge tests (i.e. Acthrel and Cortrosyn) and serial blood collections on separate days

Compensation is up to $250.
The title of the study is SCOR Hormone Challenge.

If interested, please call (310) 206-1719

If so, and you are between the age of 18 and 55, you may qualify to participate in a UCLA research study conducted by Dr. Lin Chang. The purpose of this study is to compare certain components found in the saliva, blood, urine, stool, and tissue from the wall of the large intestine (colon) and responses to stressors between IBS patients and healthy adults.

Eligible participants will complete 2 visits where they will:

  • Undergo medical and psychological evaluations, fill out questionnaires, and provide saliva, blood, urine, and stool samples
  • Receive a free colon examination (flexible sigmoidoscopy)

Compensation is up to $225.
he title of the study is SCOR Colon Examination.
