IBS-SSS-C: Chinese Version of the Irritable Bowel Syndrome Severity Scoring System

The IBS-SSS-C dataset documents the translation, cross-cultural adaptation, and validation of the Chinese version of the Irritable Bowel Syndrome Severity Scoring System. Qian Li published the study on figshare under a CC-BY-4.0 license, with the last update in May 2026. The validation involved clinical trials assessing responsiveness to change (n=95), test–retest reliability (n=35), and floor-ceiling effects.

Use Cases

• Validating the Chinese IBS-SSS tool for clinical outcome assessment based on the described psychometric properties.
• Assessing responsiveness to change in IBS severity scores based on the use of adequate relief (AR) as an anchor.
• Evaluating test–retest reliability of a health questionnaire based on the reported correlation coefficients (r=0.72 total score).
• Analyzing floor and ceiling effects in clinical assessment instruments based on the reported findings for the IBS-SSS-C items.

Strengths

• Validation involved 95 participants for responsiveness and floor-ceiling analysis.
• Reported good test–retest reliability for the total score (r=0.72).
• The translation and adaptation were performed according to an official guideline and approved by the Rome Foundation.

Limitations

• The dataset is a 202.7 KB PDF document; the underlying raw clinical trial data is not provided.
• Row count and column-level documentation for any underlying data are unknown.
• The authors note further validation in larger-scale, multi-center studies is required.
