Status Information


Term Description

This questionnaire is based on the Rome III symptoms-based diagnostic criteria for the functional gastrointestinal disorders (FGIDs). It can be self-administered and takes about 15 minutes to complete. Response formats for questions include yes/no responses, a five-point ordinal response scale for conditional questions (never or rarely to always), a seven-point ordinal response scale for frequency questions (never to every day), and a few other response scales specific to an item not fitting these (e.g., questions 76, 77, and 79). A series of "red flag" or alarm symptom questions are included at the end of the questionnaire (questions 82 to 93). Although these are not part of the diagnostic criteria, they are helpful in determining whether other diagnostic studies are needed to exclude other conditions/diseases that may explain symptoms captured in this questionnaire. A positive answer to any of these questions suggests a possibility of a diagnosis other than functional gastrointestinal disorder. This questionnaire (with its coding system) is intended for research and may be used to aid diagnosis. However, it is not meant as an instrument for self-diagnosis nor does it obviate the need for medical evaluation including history, physical examination, and limited laboratory and endoscopic testing of individual patients. The questionnaire is followed by a coding system that identifies provisional (or possible) diagnoses from the responses to the questions. The presence of an "alarm" symptom does not negate a diagnosis of an FGID, but it may indicate further inquiry or testing to rule out other conditions/diseases. Similarly, an indication of psychosocial difficulties will not alter the diagnosis but should prompt health care professionals to collect more information and possibly offer appropriate treatment. In the absence of biological markers and confirmatory tests for FGIDs, their diagnosis depends on applying these criteria, performing limited testing, and judiciously excluding other conditions/diseases (e.g., with other studies). Because there are no available tests to confirm the diagnosis of functional gastrointestinal disorders (FGIDs), the Gastrointestinal Working Group suggests that limited investigation be performed to exclude other conditions/diseases that may explain the reported gastrointestinal (GI) symptoms. These should include complete blood count, erythrocyte sedimentation rate and/or C-reactive protein, electrolytes, and liver function tests. In addition, it is recommended that serology for celiac sprue be completed for patients with diarrhea, a colonoscopy be completed for patients aged 50 years old or older with functional bowel symptoms, and an upper endoscopy be completed for patients aged 50 or older with upper GI symptoms. Additional tests should be considered based on presence of alarm symptom and clinical judgment of the provider. Many clinical scientists may prefer to study only one or a few of the FGIDs. To serve such a purpose, the questionnaire may be subdivided into question and coding modules for each of the disorders of interest: esophageal, gastroduodenal, gallbladder/sphincter of Oddi, bowel, chronic abdominal pain, and anorectal disorders.
