Insights
A new Thai version of the Rome IV questionnaire for diagnosing functional gastrointestinal disorders (FGIDs) in infants and toddlers has been developed and validated. This tool shows good reliability and validity for clinical use.
Area of Science:
- Pediatric Gastroenterology
- Clinical Diagnostics
- Health Services Research
Background:
- The Rome Foundation's Rome IV criteria are globally utilized for diagnosing functional gastrointestinal disorders (FGIDs).
- A specific Thai version of the Rome IV questionnaire for neonates and toddlers was previously unavailable.
- This gap limited accurate FGID diagnosis in the Thai pediatric population.
Purpose of the Study:
- To develop and validate a Thai translation of the Rome IV diagnostic questionnaire.
- To adapt the questionnaire for diagnosing FGIDs in neonates and toddlers in Thailand.
- To ensure the tool's suitability for clinical and research applications.
Main Methods:
- Translation of the Rome IV questionnaire into Thai following established guidelines.
- Assessment of validity using item-objective congruence.
- Administration to 65 caregivers and reliability testing (Cronbach's alpha, ICC) via test-retest.
Main Results:
- The Thai-adapted questionnaire achieved an item-objective congruence index of 0.74.
- Internal consistency (Cronbach's alpha) ranged from 0.712 to 0.753 across sections.
- Test-retest reliability (ICC) ranged from 0.782 to 0.807, indicating good stability.
Conclusions:
- The Thai Rome IV diagnostic questionnaire for FGIDs in neonates and toddlers is valid and reliable.
- The developed questionnaire is suitable for future clinical practice and research in Thailand.
- This validated tool will aid in the accurate diagnosis and management of FGIDs in young Thai children.
Background:
The Rome Foundation's questionnaires, including the latest version, Rome IV diagnostic criteria since 2016, are widely used globally for diagnosing functional gastrointestinal disorders (FGIDs). However, a tailored Thai version for diagnosing FGIDs in neonates and toddlers is yet to be developed.
Aim:
To develop and validate the Thai version of the Rome IV diagnostic questionnaire for FGIDs in neonates and toddlers.
Methods:
This study was conducted at a tertiary hospital in Bangkok. The Rome IV diagnostic questionnaire for neonates and toddlers was translated into Thai following Rome Foundation guidelines. Validity was assessed using item-objective congruence. The final version was administered to 65 caregivers of children under 4 years. Reliability was evaluated using Cronbach's alpha and intraclass correlation coefficient based on test-retest responses collected over a 4-15 day interval.
Results:
A total of 58 complete questionnaires were returned. The median interval between the first and second time was 7 days (range: 4 days to 15 days). The item-objective congruence index for the Thai-adapted Rome IV diagnostic questionnaire was 0.74. Internal consistency, as indicated by Cronbach's alpha, was 0.753, 0.712, and 0.750 for the three respective sections. The intraclass correlation coefficients for test-retest reliability were 0.782, 0.782, and 0.807.
Conclusion:
The Thai Rome IV diagnostic questionnaire for FGIDs in neonates and toddlers demonstrates acceptable validity and reliability, supporting its use in future clinical and research applications.
