PLOS ONE

Journal Requirements:

When submitting your revision, we need you to address these additional requirements.

1. Please ensure that your manuscript meets PLOS ONE's style requirements, including those for file naming. The PLOS ONE style templates can be found at

https://journals.plos.org/plosone/s/file?id=wjVg/PLOSOne_formatting_sample_main_body.pdf and

https://journals.plos.org/plosone/s/file?id=ba62/PLOSOne_formatting_sample_title_authors_affiliations.pdf

2. We note that you have indicated that there are restrictions to data sharing for this study. PLOS only allows data to be available upon request if there are legal or ethical restrictions on sharing data publicly. For more information on unacceptable data access restrictions, please see http://journals.plos.org/plosone/s/data-availability#loc-unacceptable-data-access-restrictions.

Before we proceed with your manuscript, please address the following prompts:

a) If there are ethical or legal restrictions on sharing a de-identified data set, please explain them in detail (e.g., data contain potentially identifying or sensitive patient information, data are owned by a third-party organization, etc.) and who has imposed them (e.g., a Research Ethics Committee or Institutional Review Board, etc.). Please also provide contact information for a data access committee, ethics committee, or other institutional body to which data requests may be sent.

b) If there are no restrictions, please upload the minimal anonymized data set necessary to replicate your study findings to a stable, public repository and provide us with the relevant URLs, DOIs, or accession numbers. For a list of recommended repositories, please see

https://journals.plos.org/plosone/s/recommended-repositories. You also have the option of uploading the data as Supporting Information files, but we would recommend depositing data directly to a data repository if possible.

We will update your Data Availability statement on your behalf to reflect the information you provide.

3. PLOS requires an ORCID iD for the corresponding author in Editorial Manager on papers submitted after December 6th, 2016. Please ensure that you have an ORCID iD and that it is validated in Editorial Manager. To do this, go to ‘Update my Information’ (in the upper left-hand corner of the main menu), and click on the Fetch/Validate link next to the ORCID field. This will take you to the ORCID site and allow you to create a new iD or authenticate a pre-existing iD in Editorial Manager.

4. Please review your reference list to ensure that it is complete and correct. If you have cited papers that have been retracted, please include the rationale for doing so in the manuscript text, or remove these references and replace them with relevant current references. Any changes to the reference list should be mentioned in the rebuttal letter that accompanies your revised manuscript. If you need to cite a retracted article, indicate the article’s retracted status in the References list and also include a citation and full reference for the retraction notice.

Additional Editor Comments:

The authors have presented some very interesting points in the manuscript, but these sections require revision for clarity and accuracy.

Consider providing more detailed background information about the existing literature. For example, how does this study build upon prior research on the psychological impacts of COVID-19 on educators or other frontline workers?

Clarify the rationale for focusing specifically on Ontario education workers. Is there something unique about this population that warrants investigation?

Provide a clear statement of the research question or hypothesis.

The inclusion criteria mention education workers aged 18-77 who were employed in Ontario schools and working an average of ≥8 hours/week, but the exclusion criteria for those who selected "neither male nor female" as their gender are vague. Clarify why participants who selected "neither male nor female" were excluded due to "small sample size." Providing more context on this decision, such as whether the data from non-binary participants was insufficient to draw meaningful conclusions, would make this clearer. Additionally, consider expanding on the inclusion and exclusion criteria in more detail for transparency, particularly if gender diversity is a relevant aspect to the study.

The inclusion of COVID-19-specific factors (e.g., infection history, vaccination status) is mentioned, but their relationship to K10 scores is not fully explored or explained in the methodology.

Report any statistical significance (e.g., p-values or confidence intervals) for the findings related to K10 scores and associated factors. For example, was the decrease in K10 scores over time statistically significant?

The relationship between specific periods (e.g., "return-to-workplace periods") and distress could be elaborated further. How much variation in K10 scores was explained by these factors?

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: I enjoyed reading your article and found the methods generally rigorous and the findings interesting. There were a few places where I wished for some clarification to understand what was done and how better :

1) Is there a particular reason why you chose these specific start and end-dates; perhaps especially the end-dates?

2) I don't understand the mitigation scoring and variables. Would it be possible to explain what it is based on more clearly?

3) With respect to the four-week intervals respecting the K-10 scores, I think I understand what you did based on the elaboration in the results, but here too I think the methodology could be described more clearly.

**********

Additional Editor Comments:

1. Consider providing more detailed background information about the existing literature. For example, how does this study build upon prior research on the psychological impacts of COVID-19 on educators or other frontline workers?

Additional information from longitudinal studies has been added (see lines 84-99).

2. Clarify the rationale for focusing specifically on Ontario education workers. Is there something unique about this population that warrants investigation?

Additional information regarding the importance of this group of essential workers has been added to the introduction (see lines 59-65). In addition, details regarding the generalizability of this information have also been added to the limitations section (see lines 379-381).

3. Provide a clear statement of the research question or hypothesis.

The study hypothesis is now stated (see lines 105-109).

4. The inclusion criteria mention education workers aged 18-77 who were employed in Ontario schools and working an average of ≥8 hours/week, but the exclusion criteria for those who selected "neither male nor female" as their gender are vague. Clarify why participants who selected "neither male nor female" were excluded due to "small sample size." Providing more context on this decision, such as whether the data from non-binary participants was insufficient to draw meaningful conclusions, would make this clearer. Additionally, consider expanding on the inclusion and exclusion criteria in more detail for transparency, particularly if gender diversity is a relevant aspect to the study.

More detail has now been provided regarding the decision to drop those who did not select male or female as their gender (see lines 123-126).

5. The inclusion of COVID-19-specific factors (e.g., infection history, vaccination status) is mentioned, but their relationship to K10 scores is not fully explored or explained in the methodology.

More details regarding how variables were created are now provided in the section “Survey instruments” (see lines 139-173).

6. Report any statistical significance (e.g., p-values or confidence intervals) for the findings related to K10 scores and associated factors. For example, was the decrease in K10 scores over time statistically significant?

The relationship between K10 scores and the four temporal variables was statistically significant (see lines 234-240). Other significant factors are described in lines 249-254. Further, as indicated in the notes for Table 2, all factors significantly associated with K10 distress scores are bolded.

7. The relationship between specific periods (e.g., “return-to-workplace periods”) and distress could be elaborated further. How much variation in K10 scores was explained by these factors?

Details of the relationship between the temporal variables and distress are provided in lines 240-246. The model conditional R2 and the marginal R2 are reported in the Table 2 notes and now also on lines 254-257.

8. While revising your submission, please upload your figure files to the Preflight Analysis and Conversion Engine (PACE) digital diagnostic tool.

5. Review Comments to the Author

Reviewer #1: I enjoyed reading your article and found the methods generally rigorous and the findings interesting. There were a few places where I wished for some clarification to understand what was done and how better:

1) Is there a particular reason why you chose these specific start and end-dates; perhaps especially the end-dates?

The study was started once funding was obtained. Initially, funding was requested for 14 months. Then, we applied for and received additional funding to continue the study until the end of 2023. New funding was not requested for the 2024 calendar year (see lines 115-122).

2) I don't understand the mitigation scoring and variables. Would it be possible to explain what it is based on more clearly?

Additional information has now been provided (see lines 168-173)

3) With respect to the four-week intervals respecting the K-10 scores, I think I understand what you did based on the elaboration in the results, but here too I think the methodology could be described more clearly.

We hope the new wording is clearer (see lines 157-158).

RE: Minor Revisions for Manuscript PONE-D-24-47690R2, "Changes in emotional distress among Ontario education workers during the COVID-19 pandemic: 2021-2023"

Dear Dr. Coleman,

Thank you for your resubmission of the manuscript referenced above to PLOS ONE. We commend you and your co-authors for the thorough and thoughtful revisions, which have substantially strengthened the manuscript and successfully addressed the primary concerns raised by the reviewers. The addition of comparative literature for other essential worker sectors has significantly enhanced the context and impact of your findings.

The manuscript is now very close to being suitable for publication. To further elevate its contribution, we recommend a final set of minor revisions focused on deepening the interpretation and sharpening the conclusions. Please find our specific suggestions below.

List of Recommended Revisions

1. Deepen the Interpretive Analysis in the Discussion Section

Location: In the Discussion section, as a new paragraph following the comparison with healthcare and other essential workers (i.e., after line 341 in the track-changes manuscript).

Rationale: To move beyond reporting the comparison and interpret why educators might have experienced higher levels of distress, thereby strengthening the manuscript’s analytical contribution.

Current Text (end of the paragraph):

"...lower than what was found in the current study (2021: 54.7%; 2023: 32.5%) but, in both cases, much higher than what is expected in the general population [44]."

Proposed Text (with new paragraph added):

"...lower than what was found in the current study (2021: 54.7%; 2023: 32.5%) but, in both cases, much higher than what is expected in the general population [44].

The finding that education workers, at times, reported higher levels of distress than even frontline healthcare providers warrants further consideration. This discrepancy may be attributable to several factors unique to the education sector. Unlike healthcare professionals, who are trained for crisis response, educators were thrust into a public health crisis with little to no specific preparation, while simultaneously managing the pedagogical, emotional, and safety needs of children. Furthermore, the intense public and political scrutiny surrounding school closures and reopenings placed educators at the center of a contentious societal debate. This confluence of responsibilities, acting as de facto frontline workers while maintaining educational continuity and navigating significant public pressure, likely created a unique and potent combination of stressors not experienced in the same way by other worker groups."

2. Strengthen the Policy Implications in the Conclusion Sub-section

Location: At the end of the "Conclusions" section, following the final sentence (after line 409).

Rationale: To provide a clear, actionable takeaway that highlights the practical and policy relevance of the research findings.

Current Text (final sentence):

"Further research into best practices in early distress identification and remediation is warranted to ensure future pandemics are met with education systems and workers who can continue to provide an exceptional learning experience ."

Proposed Text (with new sentences added):

"Further research into best practices in early distress identification and remediation is warranted to ensure future pandemics are met with education systems and workers who can continue to provide an exceptional learning experience .

Therefore, these findings underscore the need for education authorities to move beyond reactive measures and develop proactive, institutional-level mental health frameworks. Such frameworks should include targeted support for high-risk demographics and provide evidence-based strategies to manage workload and mitigate distress during future public health crises or other systemic disruptions."

3. Enhance the Link Between Data (Figure 1) and Interpretation in the Discussion Section

Location: In the Discussion section, within the paragraph discussing the effect of summer vacations (starts around line 345).

Rationale: To explicitly connect the striking visual data from Figure 1 to the interpretation, reinforcing the argument about the impact of acute environmental factors.

Current Text:

"In the current study, distress levels were lower during Ontario education worker vacation periods (summers). This corroborates previous research that reported a strong, but limited, positive effect of vacations on mood [46] ."

Proposed Text (with new sentence integrated):

"In the current study, distress levels were lower during Ontario education worker vacation periods (summers).

The pronounced fluctuations observed in Figure 1, particularly the sharp decrease in distress during summer and the subsequent spike upon returning to the workplace, highlight the significant and immediate impact of work-related environmental factors. This corroborates previous research that reported a strong, but limited, positive effect of vacations on mood [46] ."

Please consider the specific phrasing provided in these recommendations as illustrative examples designed to guide your revisions. We encourage you to adapt this guidance in a manner that best aligns with your own authorial voice and the overall narrative of the manuscript.

We believe that incorporating these minor revisions will make your manuscript an even more impactful and compelling contribution to the field. We look forward to receiving the revised version.

Sincerely,

The Editor
