Reviewer 2 Report

Congratulations for the work, but the research results are predictable in the context of the restrictions caused by the pandemic.

Introduction: The introduction is clear and refers to the results obtained;

Citations: The citations support the context of the research, but it must be improved with articles that already talk about the predictability of its specificity;

Methodology of research 

There are some deficiencies determined by:

1. the lack of the Alpha Cronbach coefficient for the questionnaire (which shows the degree of fidelity of the items);

2. the groups are not equivalent, regarding the listed variables (gender, type of institution, etc.);

3. r (Pearson) or p (Spearman) values are not interpreted (if a relationship between PA and SB is to be identified)

4. the values of r (Pearson) or p (Spearman) are not interpreted (if one wants to identify a relationship between PA and SB) the value;

5. what is the result of linear regression?

Conclusions: the conclusion regarding the statistical methods mentioned in the content of the work is missing
