Background: Available stool form scales do not optimally capture the continuum of stool consistency experienced by patients with irritable bowel syndrome with diarrhea (IBS-D). This paper describes the development of a new measure to assess stool form and consistency for IBS-D. Methods: Descriptors for a new scale were selected by comparing spontaneous descriptions of stools from patients with IBS-D (Rome III) with spontaneous patient descriptions of images in the Bristol Stool Form Scale… 

Figures and Tables from this paper

Evaluation and performance of a newly developed patient-reported outcome instrument for diarrhea-predominant irritable bowel syndrome in a clinical study population
Evidence is provided of the psychometric properties of the IBS-D Daily Symptom Diary and Event Log in a clinical trial population and these results are aligned with the previous standalone psychometric study regarding reliability and validity tests.
Diarrhea-predominant irritable bowel syndrome: creation of an electronic version of a patient-reported outcome instrument by conversion from a pen-and-paper version and evaluation of their equivalence
This study indicates that the two administration modes are conceptually equivalent, and both are psychometrically reliable, as established in the pen-and-paper version.
Cultural adaptation: translatability assessment and linguistic validation of the patient-reported outcome instrument for irritable bowel syndrome with diarrhea
The translation and linguistic validation of the IBS-D PRO instrument into Spanish (US) and Japanese provide evidence that this instrument can be used in multinational trials and clinical settings.


Stool form scale as a useful guide to intestinal transit time.
This study has shown that a stool form scale can be used to monitor change in intestinal function and such scales have utility in both clinical practice and research.
A prospective assessment of bowel habit in irritable bowel syndrome in women: defining an alternator.
Female patients with IBS entering a National Institutes of Health treatment trial were studied at baseline with questionnaires and 2-week daily diary cards of pain and stool frequency and consistency, and Rome II criteria was used to prospectively assess change in bowel habit for more than 1 year to understand IBS-A.
Validation of a new measure of diarrhea
A questionnaire to assess diarrhea severity and complications was developed and administered to 205 HIV positive patients with diarrhea, fever, or weight loss, and both verbal and pictorial stool descriptors correlated well with diarrhea complications.
Psychometric evaluation of patient-reported outcomes in irritable bowel syndrome randomized controlled trials: a Rome Foundation report.
Both the traditional binary and 50% improvement end points are equivalent in their psychometric properties, neither is impacted by baseline severity, and both demonstrate excellent construct validity.
An Evidence-Based Position Statement on the Management of Irritable Bowel Syndrome
This monograph was developed to educate physicians about its epidemiology, diagnostic approach, and treatments of Irritable Bowel Syndrome to critically evaluate the rapidly expanding research about IBS.
Qualitative Development of a Patient-Reported Outcome Symptom Measure in Diarrhea-Predominant Irritable Bowel Syndrome
The IBS-D Symptom Diary and Event Log represent a rigorously developed PRO instrument for the measurement of the IBS -D symptom experience from the perspective of the patient and its content validity has been supported.
Defecation frequency and timing, and stool form in the general population: a prospective study.
It is concluded that conventionally normal bowel function is enjoyed by less than half the population and that, in this aspect of human physiology, younger women are especially disadvantaged.
Functional Bowel Disorders.
Advances in the understanding of the pathophysiology of FBD, particularly IBS, published in Gastroenterology has led to the current appreciation that FBD represent dysfunction in the bidirectional brain-gut axis, intestinal barrier dysfunction and interactions with the microbiota and dietary factors.
