Study Overview
Brief Summary
The aim of this study is to assess interobserver and intraobserver variability of the Amsterdam Stool Scale in clinical practice. After passing a stool by the child participating in the study it will be assessed using the Amsterdam Stool Scale independently by one of the parents and the medical doctor. At the same time a parent will take 2 photos that will be independently evaluated by another doctor.
Detailed Description
INTRODUCTION:
Description of stool appearance is important in clinical practice. Parents are often asked to evaluate stool of their child. At present parents also take more frequently photos using smartphone camera when they are concerned with child's stool appearance and show it to their doctors. To make stool evaluation easier there have been stool form scales created. One of this is Amsterdam Stool Scale that enables stool assessment of children who are not yet toilet trained. This scale facilitates to describe amount, consistency and color of the stool.
AIM:
To assess interobserver and intraobserver variability of the Amsterdam Stool Scale in clinical practice.

Outcomes
Primary Outcomes
Interrater Variability (IV)
Time Frame: <5min after defecation
The outcome measures were interrater variability in the stool assessment by the parent and MD1 made in vivo and in the assessment by the parent in vivo and by MD2 based on the photograph(s). The IV was evaluated by calculating the proportion of exact agreement and the κ statistics for nominal data (colour) and weighted κ values for items in which there is a natural ordering of categories (consistency and amount). Correlation, based on the value of kappa (κ), was categorized as poor (κ ≤ 0.2), fair (0.21 ≤ κ ≤ 0.40), moderate (0.41 ≤ κ ≤ 0.60), good (0.61 ≤ κ ≤ 0.80) or excellent (0.81 ≤ κ ≤ 1.00).
