Dispositional Resilience as Mediator in Psychological Stress on Healthcare Workers: A Multi-Group Analysis of Frontline and Non-Frontline Workers

This is an excellent article which summarize the main topics of the study, arguments, positions, analysis and findings. In my point of view, the paper provides new knowledge of this field of research and it can be published with no additional revisions

We thank the reviewer for his comments motivating our work.

The introduction section should be extended by providing more research results regarding relationships among the variables examined. In addition, please justify more thoroughly why resilience can mediate the association between stress and quality of life. Linking some sentences in Introduction is also needed to create a more coherent structure.

We thank the reviewer for his comments. We have expanded the introduction and inserted linking sentences. In addition, we have added further explanations on how resilience can have a mediating effect. We thank you again for your suggestions.

First of all, congratulations for choosing a highly topical issue.

We thank the reviewer for his suggestions and comments, they helped us a lot to improve the paper.

We thank the reviewer for the valuable suggestion. Thanks to the bibliography you have provided us, we have integrated some information in the introduction about the quality of professional life of health professionals from the beginning of the pandemic to today
