Cognitive Mediators of Bowel Discomfort: An Exploratory Study NEW
Swinburne University of Technology, Hawthorn, Victoria Australia
Do psychological concerns drive your bowel discomfort – help us develop a scale to better measure these processes.
Psychological distress and gastrointestinal symptoms commonly occur together and are frequently reported in community samples. Your responses will help us better understand how thinking patterns impact upon gastrointestinal discomfort. Further your participation will also help us to develop a new scale that can help better identify and target psychological processes associated with gastrointestinal discomfort. The study involves completing an online questionnaire which should take approximately 60 minutes to complete.

Thought Impact Scale Online Study, University of North Carolina/Chapel Hill NEW
Dr. Palsson is a leading international researcher of IBS and its psychological aspects. The current study is not specific to IBS or any other chronic medical condition, and study volunteers need not have a medical condition, but if the Thought Impact Scale is validated through this and other research, it has potential applications for psychological interventions for IBS and other conditions.
Dr. Palsson is seeking adult volunteers aged 18 or over who are fluent in English and reside in the United States to complete two 25 minute surveys 30 days apart. You must be willing to provide him with your first name and an email address so that he can send a participant code number and password, but responses to the surveys themselves are anonymous and cannot be linked in the study database to personally identifying information.
Please address any additional questions or concerns about the study directly to Dr. Palsson at email@example.com

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