Insights
A new scale, the Gastrointestinal and Gastroesophageal Reflux (GIGER) Scale for Infants and Toddlers, effectively measures GI and GER symptoms in children under two. This parent-reported tool demonstrates reliable psychometric properties for clinical use.
Area of Science:
- Pediatric Gastroenterology
- Clinical Psychology
- Child Health Research
Background:
- Gastrointestinal (GI) and gastroesophageal reflux (GER) symptoms are common in infants and toddlers.
- Accurate assessment tools are crucial for diagnosis and management.
- Existing measures may not comprehensively capture parent-observable symptoms.
Purpose of the Study:
- To develop and validate the Gastrointestinal and Gastroesophageal Reflux (GIGER) Scale for Infants and Toddlers.
- To assess the factor structure and psychometric properties of the GIGER Scale.
- To provide a reliable parent-report measure for GI and GER symptoms in young children.
Main Methods:
- Item development to capture parent-observable GI and GER symptoms.
- Exploratory factor analysis on data from 391 parents of children under 2 years old.
- Reliability (internal consistency) and validity (correlation with existing scales, group comparisons) analyses were performed.
Main Results:
- A 36-item GIGER Scale with 3 subscales was identified through factor analysis.
- The scale demonstrated acceptable internal consistency (α = .78–.94).
- GIGER scores correlated significantly with established measures (I-GERQ-R, IGSQ) and were higher in infants diagnosed with GER or constipation.
Conclusions:
- The GIGER Scale is a psychometrically sound, parent-report instrument for assessing GI and GER symptoms in children under 2 years old.
- The scale's factor structure and reliability support its use in clinical and research settings.
- The GIGER Scale aids in identifying infants experiencing significant gastrointestinal and reflux issues.
Abstract:
The purpose of this study was to describe the development of the Gastrointestinal and Gastroesophageal Reflux (GIGER) Scale for Infants and Toddlers, and determine its factor structure and psychometric properties. Items were developed to comprehensively assess gastrointestinal (GI) and gastroesophageal reflux (GER) symptoms observable by a parent. Exploratory factor analysis on 391 responses from parents of children under 2 years old resulted in a 36-item scale with 3 subscales. Internal consistency reliability was acceptable (α = .78-.94). The GIGER total score and all 3 subscales were correlated with the Infant Gastroesophageal Reflux Questionnaire-Revised (I-GERQ-R) (P < .05) and Infant Gastrointestinal Symptoms Questionnaire (IGSQ) (P < .05). GIGER total score was higher in infants with a diagnosis of GER (P < .05) or constipation (P < .05) compared to those without. The GIGER is a parent-report measure of GI and GER symptoms in children under 2 years old with adequate psychometric properties.
