Title: Developing the modified 4-item version of Perceived Stress Scale for functional dyspepsia
Version: 1 Date: 08 Feb 2023
Reviewer's report:
-The article has typographical and grammatical errors
- The objectives are not specific
- The methodology does not follow the objectives. Too many scales are used to assess anxiety,
depression, quality of life and stress, while only stress has been mentioned in the objective
- Sample size estimation for the study is not clear. Was a formula or software used?
- Why was CONSORT guidelines or checklist used, for this particular study design?
- When ANOVA was used in statistical analysis and significant difference was found, why was
post hoc test not used.
- Table 1 is for demographic characteristics. It does not show "that female patients were more
common in FD, and the education level of patients was generally low, mainly in middle school"
though it is mentioned in text under demographic characteristics.
- Shouldn't the new modified  PSS-4 be tested again for validity and reliability in a group of
patients before coming to a conclusion regarding it being a more valid and reliable tool?
