Reviewer 1 Report

Dear Authors,

Congratulations for your research, it is simple, clear and precise. However, as a reviewer, I recommend you to make some small nuances.

 

First of all, the introduction is very brief. I understand that research should be synthetic, but you should extend the explanation to smartphones. There are few references about smartphone addiction, so I think they should be based on Internet addiction or problematic Internet use. Explain what it is, and above all what social and personal needs are involved. There is also a strong relationship between addiction or problematic internet use and depression, this variable can be very interesting. There are meta-analyses that address these issues, review them and add the information you find.  In the introduction I miss a review of the role of sex in addiction and suicide, add a paragraph on this aspect. Remember that all these new references and new information should appear in the discussion.

 

The discussion is interesting but you need to counter the information more with other research. Add more references and add to the discussion.

 

The methodology and results are correct, very clear and precise. 

 

Congratulations for your work

Reviewer 2 Report

The statistical analyses reported in this paper appear reasonably well done. Their descriptions in the text of the paper can be improved, however. Here are some things to attend to.

The "Result" section should be labeled "Results".

In the second paragraph of this section that begins with "Table 2 shows the association between...", you need to make clear in this sentence and in the title of the table that these are bivariate associations and that the p-values are for the Chi-squared statistics that measure these associations.

Similarly, in the title of Table 3 and in the text, you need to make clear that these are the estimates from the multivariate logistic regression analyses.

In general, all of the paragraphs describing the results of the statistical analyses need careful elaboration and details of the analyses and findings. 

Regarding the statistical analyses, you also need to address the question of whether your analyses found any statistically significant interactions among the regressors.
