Interpretive Summary: The quality of life of patients is receiving increasing attention. We developed a questionnaire that measures the quality of life of patients related to gastrointestinal problems and worrying. In this study, we determined what normal values are for this questionnaire so it can be used to compare children with gastrointestinal problems to healthy children.
Technical Abstract: The present study investigates the clinical interpretability of the Pediatric Quality of Life Inventor (PedsQL) Gastrointestinal Symptoms Scales and Worry Scales in pediatric patients with functional gastrointestinal disorders or organic gastrointestinal diseases in comparison with healthy controls. The PedsQL Gastrointestinal Scales were completed by 587 patients with gastrointestinal disorders/diseases and 685 parents, and 513 healthy children and 337 parents. Minimal important difference (MID) scores were derived from the standard error of measurement (SEM). Cut-points were derived based on one and two standard deviations (SDs) from the healthy reference means. The percentages of patients below the scales' cut-points were significantly greater than the healthy controls (most p values'='.001). Scale scores 2 SDs from the healthy reference means were within the range of scores for pediatric patients with a gastrointestinal disorder. MID values were generated using the SEM.The findings support the clinical interpretability of the new PedsQL Gastrointestinal Symptoms Scales and Worry Scales.
