Validation of the youth version of the Alimetry® Gut-Brain Wellbeing Survey: a mental health scale for young people with chronic gastroduodenal symptoms.
Article in World journal of pediatrics : WJP, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis research outlines the development and validation of the Alimetry® Gut-Brain Wellbeing Survey-Youth Version (AGBW-Y), a novel tool for assessing mental health in young people with chronic gastroduodenal symptoms aged 12-17 years.
methodsIn Phase 1, global feedback was gathered from 19 pediatric clinicians in the gastroenterology field and 33 young people over multiple rounds to make the adult AGBW Survey more age-appropriate for young people. In Phase 2, rigorous psychometric testing was conducted in a sample of 128 patients aged 12-17 years with chronic gastroduodenal symptoms, using an anonymous survey.
resultsBased on the feedback from Phase 1, an interdisciplinary team of experts improved the survey's language and usability for young people to enhance the scale's clarity, acceptability, and face and content validity. The final AGBW-Y comprises a patient preface, 10 closed-ended questions, and an open-ended question. It assesses general mental health, alongside subscales of depression, stress, and anxiety. Phase 2 demonstrated excellent psychometric properties of the scale, including high internal consistency reliability (α = 0.91 for the total scale; α = 0.75-0.85 for subscales) and strong convergent, divergent, and concurrent validity with large effect sizes.
conclusionsThe AGBW-Y is a brief, reliable, and valid tool to assess mental health in young people aged 12-17 years with chronic gastroduodenal symptoms. This novel scale was developed through rigorous co-design with clinicians and young people, ensuring it is contextually relevant and clinically impactful. The AGBW-Y complements existing physiological assessments, enabling evaluations that can guide psychological referrals, support multidisciplinary care, and evaluate treatment outcomes.
