The Intestinal Gas Questionnaire (IGQ): Psychometric validation of a new instrument for measuring gas‐related symptoms and their impact on daily life among general population and irritable bowel syndrome

“…Two questionnaires were used for the selection of participants. First, a simple symptom screening tool (SST), which assessed the frequency of four GRS (bloating, flatulence, belching, and stomach rumbling) in the past month (from 0 = never to 5 = every day), with a global score ranging from 0 to 20 19 . Second, the IBS‐SSS questionnaire 20 which measured intensity and frequency of abdominal pain, bloating/distension, dissatisfaction with bowel habit, and interference on daily life (score range: 0‐500).…”

“…IGQ results from a previous qualitative research analysis 19 . The 43‐item pilot IGQ consists of a 24‐hour recall symptom diary assessing 7 GRS (17 items) and a 7‐day recall questionnaire which assesses the impact of those symptoms on 12 domains (26 items).…”

“…IGQ results from a previous qualitative research analysis. 19 The 43item pilot IGQ consists of a 24-hour recall symptom diary assessing 7 GRS (17 items) and a 7-day recall questionnaire which assesses the impact of those symptoms on 12 domains (26 items). The 7 GRS are as follows: abdominal distension, abdominal pressure/feeling bloated, flatulence, belching, bad breath, stomach rumbling, and difficult gas evacuation.…”

“…The 12 impact domains are as follows: clothing, emotional, diet, cognitive function, physical appearance, work, sexual life, physical activity, social life, sleep, activities of daily living, and partner relationship. 19 Answer options are 0-10 numerical and Likert scales. The maximum score is 500, 20 it is used to classify IBS symptoms as mild (<75), moderate (75-299), and severe ≥ 300.…”

“…The 7 GRS were as follows: abdominal distension, abdominal pressure/feeling bloated, flatulence, belching, bad breath, stomach rumbling, and difficult gas evacuation. 19 The aim of the current work was to perform a psychometric validation and to develop a shorter IGQ version with the selection of final items and factor structure. This aim was carried out in samples of GPop and IBS patients in UK, France, and Spain.…”
