Hence, I urge the authors not to mislead readers and to re-write these sections.
Wrong use of abbreviations: The authors introduced the abbreviation “GHQ-12” for the 12-item General Health Questionnaire (see page 4, line 161), but wrote in the text only "GHQ" (e.g., page 5, line 207; page 6, line 256; page 7, line 274). Please replace every single “GHQ” in the text with the correct abbreviation “GHQ-12”. Please repeat this procedure for “PSS-10” (see page 4, line 185), i.e. replace “PSS” with “PSS-10” in the whole text.
