Online Research Survey on Chronic Abdominal Pain    NEW

Stanford University and International Foundation for Gastrointestinal Disorders (IFFGD)

The following anonymous and confidential research survey is open to adults 18 years old or older from any country who have had a chronic abdominal pain condition (IBS and/or many others) for at least 6 months. The survey will ask demographic information, symptom information, and treatment information for current or past interventions and their level of effectiveness. This study has Stanford institutional review board approval. Estimated completion time is 15 minutes.


Gastrointestinal Unhelpful Thinking Scale (GUTS) Development Study  NEW

Swinburne University of Technology, Hawthon, Victoria, Australia

and Icahn Mount Sinai, New York City, USA.

The following anonymous online study is currently seeking men and women at least 18 years old in any country with chronic gastrointestinal conditions is a followup to online studies posted here in 2017 and 2018. The 2017 and 2018 studies are now closed to new volunteers.

The current study has received institutional ethical approval. All information available to IBS Impact is below and at the study link. Please address any further questions or concerns directly to the research team at the phone number or email address given below. This description is adapted from excerpts of the one on the study page.

In 2017 and 2018 we conducted a study which developed a new scale (Gastrointestinal Unhelpful Thinking Scale [GUTS]) to assess cognitive processes associated with bowel discomfort. We are now conducting a new study and looking for both male and female participants who are at least 18 years of age. The current project is exploring how responses to the GUTS relate to other similar scales. 

Your responses will help us better understand how thinking patterns impact upon gastrointestinal discomfort. Further your participation will also help us to evaluate our new scale against other similar scales. We hope that the validation of our new scale will lead to better way to measure and assess common cognitive factors associated with bowel discomfort.

Estimated time commitment is 30 minutes. All information provided is anonymous. At the completion of the study, participants may opt in to providing an email address for a random drawing to receive one of four AUS $100 gift cards to Amazon or Coles Meyer or JB HIFI, but this is not required. The drawing is scheduled to take place on October 31, 2019.

ContactME-IBS Registry of Potential Volunteers for Research Studies

County Durham and Darlington NHS FoundationTrust, United Kingdom

Seeking adults, 18+ years old, United Kingdom residents only with a diagnosis of irritable bowel syndrome. This registry has been newly launched in September 2017 as part of a 5 year study. If successful, it may be expanded to other locations in the United Kingdom. The registry is designed to assist people with IBS in learning about available research opportunities and assist researchers in recruiting more interested volunteers. As eligibility requirements for different studies vary, it is not a guarantee that a given individual will be contacted for or qualify for a specific study, and there is no obligation to participate in a specific study if offered. You are only expressing interest and giving researchers permission to contact you in the future.


(Note from IBS Impact: As this is a new venture, as of 2018, portions of the website are still under construction, but we have verified from reputable sources in the IBS community that this is a legitimate opportunity.)

Evaluation of Post-Traumatic Stress Disorder in Patients with Inflammatory Bowel Disease, Irritable Bowel Syndrome, and Breast Cancer 

Online Study, Northwestern University Department of Gastroenterology and Hepatology

“We are asking you to take part in this research study because we are trying to learn more about the experiences patients living with inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), and breast cancer may have with trauma, including post-traumatic stress disorder.”

Seeking adults, 18 or older. Estimated time for completion 45 minutes. Principal investigator:  Dr. Tiffany Taft, PsyD. at ttaft@northwestern.edu or 312-725-6175.


Noisy Guts Project, Marshall Centre, University of Western Australia, Perth 

The Marshall Centre, founded by Professor Barry Marshall, Nobel Laureate for his work connecting H. pylori infection to ulcers, is seeking adult volunteers with irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and without gastrointestinal conditions to assist in developing a non-invasive acoustic belt. It is hoped that the belt, which records gut sounds, heart rate, temperature and skin galvanic response, can eventually serve as a tool for the diagnosis of GI disorders.

Commitment includes online screening, consent to confirm diagnosis with one’s physician, one visit to the Marshall Centre for about 2 hours and 40 minutes of wearing the belt, plus provided breakfast, completion of online log of diet and symptoms.  Option to wear the belt home for 24 hours.
