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.
