Summary
A new pediatric stool scale, based on the Bristol Stool Form Scale, shows high reliability and agreement among pediatric gastroenterologists for assessing stool form in children.
Area of Science:
- Pediatric Gastroenterology
- Clinical Assessment Tools
Background:
- Accurate assessment of stool form is crucial in pediatric gastroenterology.
- Existing tools may require adaptation for pediatric populations.
Purpose of the Study:
- To develop a pediatric stool form rating scale.
- To evaluate its interrater and intrarater reliability and agreement among specialists.
Main Methods:
- Modified Bristol Stool Form Scale with 5 categories developed.
- 14 pediatric gastroenterologists rated 32 stool photographs.
- 10 raters reassessed photographs after 6 months.
Main Results:
- 94% of ratings were within one category of the modal rating.
- High interrater reliability (ICC=0.85) and intrarater reliability (ICC=0.87) observed.
- Complete agreement among all raters for 25% of stool photographs.
Conclusions:
- The modified pediatric Bristol Stool Form Scale demonstrates excellent reliability and agreement.
- This scale is a valuable tool for standardizing stool form assessment in children.
