Title: Developing the modified 4-item version of Perceived Stress Scale for functional dyspepsia
Version: 1 Date: 03 Oct 2022
Reviewer's report:
The study will make an important contribution to the literature. however, the fit index values 
did not fully meet some criteria for scale validity. For example, the acceptable value of x2 /df
is below 5. Also, the RMSA value must be less than 0.08. Are some fit index values acceptable
enough for the scale to be valid? These points should be reconsidered. In my opinion, for the
validity of the scale, if it was not used as a parallel form, the regression analyzes should be
published in another article.
