Title: Development and Validation of a 13-Item Short Version of the Inflammatory Bowel
Disease Self-Efficacy Scale
Version: 0 Date: 30 Dec 2023
Reviewer's report:
Fascinating manuscript in the context of providing a shortened version of  IBD-SES  for use in
routine practice. However, some points are needed for further clarification.
1. The authors used a specific technique for item reduction. I believe it would be beneficial for
the reader to know how they selected this methodology. Please justify and add a reference
2. Two-week recall period is rather short. Why did the authors select this time point? Please
justify
3. The measuring properties of the shortened version were not evaluated to their full extent. For
example, I did not find all the aspects of validity investigated. Does this matter? If yes please
add or discuss under the limitations. Also is there any minimal important change, measurement
error etc that the reader might find useful to know
