Reviewer 1 Report
This is a relevant, well written paper. I saved in the PDF some suggestions to improvement:
- Present here a brief description of SpNQ, namely what it evaluates in the Introduction section;
- The reader will not understand the added value of using the Item Response Theory (IRT) for the psychometric assessment of the instrument. This option should be better explained, namely the limitations of the called "classic tests"
- Please present the main limitations of CTT;
