Insights
The IBD-KID2 tool effectively assesses knowledge in children with inflammatory bowel disease (IBD). This validated and reliable assessment tool aids in managing pediatric IBD by identifying knowledge gaps.
Area of Science:
- Pediatric Gastroenterology
- Health Psychology
Background:
- Knowledge of inflammatory bowel disease (IBD) and its treatment is crucial for adherence and self-management in children.
- Assessing this knowledge is vital for identifying deficits that may impact disease management.
- The IBD-KID2 is a knowledge assessment tool specifically designed for children aged 8 and above with IBD.
Purpose of the Study:
- To examine the validity and reliability of the IBD-KID2 tool.
- To assess the tool's effectiveness in a pediatric IBD population and compare it with other groups.
Main Methods:
- The IBD-KID2 was administered to four groups: children with IBD (n=22), children without IBD (n=20), medical staff (n=15), and administration staff (n=15).
- Analysis of variance (ANOVA) was used to test between-group differences, with pairwise comparisons against the IBD group.
- Test-retest reliability was determined through repeat assessments in the IBD group (n=21).
Main Results:
- Significant differences in mean scores were observed between the IBD group and all comparator groups.
- The IBD group's mean scores were 8.5 (±2.3), compared to 3.7 (±2.2) for children without IBD.
- Test-retest reliability was high (Intraclass Correlation Coefficient = 0.82), with no significant score changes upon retesting. Internal reliability was 0.85.
Conclusions:
- The IBD-KID2 tool demonstrated the ability to differentiate between groups with varying levels of IBD knowledge.
- Repeat assessments confirmed good reproducibility and comparable scores, indicating strong test-retest reliability.
- IBD-KID2 is confirmed as a valid and reliable instrument for assessing knowledge in the pediatric IBD population.
Introduction:
For children with inflammatory bowel disease (IBD), acquired knowledge of their condition and treatment is integral to their adherence and self-management. Assessing their knowledge is vital to identify deficits that may affect disease management. IBD-KID2 is a knowledge assessment tool written for children aged 8 years and over with IBD.
Objectives:
In order to examine validity and reliability, a study was carried out using IBD-KID2 in a paediatric IBD population and a number of comparator groups with established levels of IBD knowledge.
Methods:
IBD-KID2 was administered to 4 participant groups in Christchurch Hospital, New Zealand: children with IBD (n = 22), children without IBD (n = 20), medical staff (n = 15), and administration staff (n = 15). Between-group differences were tested using ANOVA and pairwise comparisons made with the IBD group. Repeat assessments by the IBD group determined test-retest reliability (n = 21).
Results:
The mean age (range) of the paediatric groups were: IBD 13.3 years (8-18), without IBD 11.9 years (8-15). Group mean scores (SD) were: IBD 8.5 (±2.3), without IBD 3.7 (±2.2), medical staff 13.5 (±1.3), administration staff 6.3 (±2.5). Group means were all significantly different to the IBD group. Test-retest mean at baseline (8.4, CI ±2.4) and repeat (9.0, CI ±2.4) were not significant. Intraclass correlation coefficient was 0.82. Internal reliability was 0.85, and item-total statistics showed no improvement by specific item removal.
Conclusions:
IBD-KID2 could distinguish between groups with different knowledge levels. Repeat assessment shows comparable scores on retest and good reproducibility. IBD-KID2 is a valid and reliable tool for use in the paediatric IBD population.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
