Development and psychometric testing of the Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS)

BACKGROUND The aim of this study was to develop and psychometrically test a short, patient-reported questionnaire to be used in clinical practice for patients with Irritable Bowel Syndrome (IBS). The Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS) questionnaire was designed to measure the treatment response of symptoms and well-being in patients suffering from IBS. METHODS The VA...

Evaluation of gastrointestinal symptoms in different patient groups using the visual analogue scale for irritable bowel syndrome (VAS-IBS)

BACKGROUND Irritable bowel syndrome (IBS) and gastrointestinal (GI) dysmotility disorders have a similar clinical picture, although dysmotility disorders require the attention of a specialist. Patients with primary Sjögren's syndrome (pSS) have also been described to suffer from IBS-like symptoms. No objective marker is available to distinguish between the patients. A visual analogue scale has ...

Irritable Bowel Syndrome (IBS): Introduction

Irritable Bowel Syndrome (IBS), which is classified as a functional gastrointestinal disorder, is a chronic condition of the lower gastrointestinal tract (Figure 1) that affects as many as 15% of adults in the United States. Not easily characterized by structural abnormalities, infection, or metabolic disturbances, the underlying mechanisms of IBS have for many years remained unclear. Recent re...

Irritable Bowel Syndrome (IBS) and Diet

The role of diet in patients with Irritable Bowel Syndrome still remains empirical, as the underlying pathophysiologic disturbances of this disorder are not fully elucidated and randomised controlled trials are difficult to perform. The mainstey for dietary manipulation still remains the exclusion diets. The new, in this field is that the “forbidden” foods are fewer than in the past and the die...
