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

Gas-related symptoms; Patient-reported outcomes; Quality of lifeSíntomas relacionados con los gases; Resultados informados por el paciente; Calidad de vidaSímptomes relacionats amb els gasos; Resultats informats pel pacient; Qualitat de vidaBackground Gas-related symptoms (GRS) are common in the general population (GPop) and among patients with disorders of gut-brain interactions but there is no patient-reported outcome evaluating these symptoms and their impact on daily life. We have previously developed a 43-item intestinal gas questionnaire (IGQ). The aim of the present study is to perform a psychometric validation of this instrument. Methods Participants (119 from the GPop and 186 irritable bowel syndrome (IBS) patients) were recruited from 3 countries (UK, Spain, France). IBS patients fulfilled ROME IV criteria with an IBS severity score between 150 and 300. Participants completed the IGQ, the functional Digestive Disorders Quality of Life (FDDQL), and the EQ-5D. A subgroup (n = 90) repeated the IGQ completion after 7 days on paper or electronically. Results From the original IGQ questionnaire, 26 items were deleted because of poor performance. Confirmatory factorial analysis on the remaining 17 items (7 symptom and 10 impact items) yielded a 6-factor structure accounting for 67% of the variance for bloating (6 items), flatulence (3), belching (2), bad breath (2), stomach rumbling (2), and difficult gas evacuation (2). Global score (0-100) was worse among IBS vs GPop (40 ± 15 vs 33 ± 17; p = 0.0016). At the second visit, the intraclass correlation coefficient of IGQ scores was between 0.71 and 0.86 (n = 67) for test-retest reliability and 0.61-0.87 (n = 64) for equivalence between electronic and paper versions of IGQ. Conclusion The IGQ available in paper and electronic versions in 3 languages is a robust instrument for capturing and measuring GRS and their impact on daily life.This Investigator Sponsored Study has been funded by Danone Research.

« Quelle conscience de mes compétences à l’écrit ? » Étude du « degré de lucidité » chez les étudiants

Notre contribution s’inscrit dans le champ des littéracies avancées et envisage plus particulièrement les compétences rédactionnelles des étudiants en français écrit et le développement possible de celles-ci. Nous examinons le degré de conscience qu’ont les scripteurs de leurs compétences dans trois domaines linguistiques : l’orthographe, la syntaxe et le lexique. Nous analysons les résultats d’une cohorte d’étudiants de premier cycle à un test mesurant les compétences rédactionnelles d’adultes francophones en français écrit (Certificat en Compétences Rédactionnelles ou CCR). Durant la passation, les candidats devaient indiquer s’ils étaient sûrs ou non des réponses qu’ils fournissaient. Ces données ont permis de calculer le degré de lucidité des candidats. Les principaux résultats indiquent des corrélations stables entre les domaines. Par ailleurs, le lexique est le domaine le moins conscientisé. Nous proposons in fine une démarche pédagogique visant explicitement le développement de la conscience métacognitive dans les formations portant sur les compétences rédactionnelles
