ABSTRACT: Aim
To validate child-adapted shortened versions of the Irritable Bowel Syndrome-Behavioural Responses Questionnaire (IBS-BRQ; short scale denoted BRQ-C) and the Visceral Sensitivity Index (VSI; short scale denoted VSI-C) for children with functional abdominal pain disorders (FAPDs).Methods
A child psychologist supervised by a child gastroenterologist was responsible for shortening the scales (BRQ-C, 11 items; and VSI-C, 7 items). Then, a sample of 89 children aged 8-12 years with FAPDs was used in the validation. Construct validity was assessed with correlations. Measures included gastrointestinal symptoms, quality of life, pain intensity and anxiety. Also, internal consistency, test-retest reliability, administration time and factor structure were assessed.Results
Internal consistency for the BRQ-C and the VSI-C was α = 0.84 and α = 0.80, respectively. Correlations with related scales were similar between child-adapted scales and original scales, indicating construct validity equivalence. Correlations between short scales and original scales were high. Mean administration time was reduced by 47% (BRQ-C) and 42% (VSI-C), compared with original scales. Test-retest reliability was r = 0.72 for BRQ-C and r = 0.83 for VSI-C. BRQ-C had two factors (Avoidance and Bowel control). VSI-C had a unifactorial structure.Conclusion
The BRQ-C and the VSI-C were found to be time-saving, reliable and valid for children with FAPDs.
