5. Review Comments to the Author

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: Changes in people's volunteering behaviors by the COVID-19 pandemic is an important topic and the manuscript was well written.

However, data collection was made among COVID-19 related volunteers during COVID-19 pandemic and this may make the findings difficult to be generalized, compared to data collection among volunteers engaging other public health issues.

It has been said that the data collection were made until data saturation was reached, however, is there any gender or age specific differences in volunteering motives?

Reviewer #2: I quite enjoyed reading this paper. It serves as an excellent example of informal, spontaneous volunteer engagement for the dissemination of public health information during a crisis Thank you for conducting this independent programme evaluation via a qualitative case study of the COVID-19 Community Champions. Maintaining positive patterns of volunteering for other public health issues beyond the pandemic is novel. Please see attached reviewer's comments for minor edits/suggestions for your revision. Thank you.

Retaining Public Health Volunteers beyond COVID-19

PLOS ONE

Dear Dr. Jolly,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we have decided that your manuscript does not meet our criteria for publication and must therefore be rejected.

Specifically:

The statistical analysis specifically approach of the Thematic analysis has not been performed appropriately and interpreted. The issues discussed in the paper are exciting but lacks appropriate analysis and have significant demographic variations in the sample. The interpretations are not in line with addressing the large deviations in the sample. Additionally, the research lacks the presence of any conceptual framework or hypothesis the authors are trying to prove. 

I am sorry that we cannot be more positive on this occasion, but hope that you appreciate the reasons for this decision.

Yours sincerely,

Revision 3

Dear Editor,

Thank you for the opportunity to engage in the peer review process in relation to this

paper, “Retaining Public Health Volunteers beyond COVID-19” (PONE-D-21-

37424R2). Both peer reviewers stated that our manuscript was well-written, focused

on an important topic, and served as “an excellent example of informal, spontaneous

volunteer engagement for the dissemination of public health information during a

crisis”. Peer reviewer feedback requested the addition of some detail about the

COVID champions volunteer programme, and some minor clarifications to the text.

Neither reviewers raised any concerns about the methodological conduct of the

study, stating that the manuscript was technically sound and the data supported the

conclusions. The previous editor requested minor clarifications, which we provided.

Therefore, we were extremely disappointed to receive the most feedback from a new

editor, and the decision to not proceed with publication. We believe the issues raised

strongly contradict the judgment of the manuscript received to date from the peer

reviewers and previous editor, thus we wish to formally appeal the decision. We

present a point-by-point response to the recent comments below.

Editorial comment: The statistical analysis specifically approach of the

Thematic analysis has not been performed appropriately and interpreted.

Thematic analysis is a form of qualitative study and is not a quantitative, statistical

approach that aims for generalisability. It was undertaken in this research by two

experienced qualitative researchers and reported transparently in accordance with

the consolidated criteria for reporting qualitative research (COREQ) checklist. The

completed checklist has been submitted along with the manuscript as an appendix.

The ‘rapid’ qualitative method reported in this manuscript pertained only to the use of

field-notes rather than verbatim transcripts, alongside a pragmatic approach to

participant recruitment, both of which were responses to the rapidly evolving context

of the pandemic. This was to ensure the experiences captured from participants

were comparable and the findings were not outdated. Rapid qualitative methods

have been found to be methodologically sound, all data were analysed and

interpreted following standard and accepted methods of thematic analysis, and

our approach is outlined in detail in the manuscript.

Editorial comment: The issues discussed in the paper are exciting but lacks

appropriate analysis and have significant demographic variations in the

sample. The interpretations are not in line with addressing the large deviations

in the sample.

Sample size calculations are not used in qualitative research, instead recruitment

and sample size are guided by the concept of data saturation. This is widely used in

qualitative research and refers to the point at which no new information is discovered

in data analysis. This is reached through a deliberate effort to recruit participants

across a wide range of demographic characteristics. This is associated with the

premise of qualitative research being to capture and understand the breadth and

diversity of experience rather than to quantify those experiences in a statistical

sense. The interpretations reported are directly from these data and a robust

approach was used through mechanisms such as double-coding, as per accepted

qualitative practice.

Editorial comment: Additionally, the research lacks the presence of any

conceptual framework or hypothesis the authors are trying to prove.

The lack of a conceptual framework/hypothesis is because the approach used was

largely inductive rather than deductive, i.e. we allowed the data to determine the

themes as we did not have pre-conceived themes we expected to find. However, we

cite the use of the Gaskin model of volunteer involvement to inform our

understanding of the topic and to formulate the initial coding frame in addition to the

research aims. A flexible iterative approach was used to allow for the exploration

of novel themes. This is an accepted and widely used approach to explore topics

with limited evidence base and diversity of experiences.

We respectfully request that the decision to reject this manuscript is reconsidered in

light of the information we have provided. We believe this topic is of interest, the

methods used are robust and have been reported transparently.

With thanks and best wishes,

Ameeta

Reviewer #5: Dear author

Your article addresses an important issue regarding volunteer work.

Some observations and suggestions to your article:

1. Qualitative data collection was carried out using different methods, but they were analyzed and computed in the same way. The collection from a focus group brings a very different result from the collection by individual interview. In the focus group, the opinions expressed are influenced by the interaction of the participants, so I would not recommend the use of different methods for this issue.

2. I would include in the methods which were the guiding topics of the focus group and which were the questions of the individual interviews.

3. I would be cautious in generalizing the results to other cultures.

Reviewer #6: This is a well-written manuscript.

The study objective is clear and the methods used are appropriate and well detailed.

In my opinion, the revisions made to issues made by previous reviewers are sufficient.

I recommend for acceptance.

Explain in the methodology part how many participants involved in semi-structured focus group discussions, one-to-one interviews and email interviews

Author Response:

Thank you – this has been reported in the results section, broken down by focus group discussions, interviews, and email interview.

Reviewer #5:

Your article addresses an important issue regarding volunteer work.

Some observations and suggestions to your article:

1. Qualitative data collection was carried out using different methods, but they were analyzed and computed in the same way. The collection from a focus group brings a very different result from the collection by individual interview. In the focus group, the opinions expressed are influenced by the interaction of the participants, so I would not recommend the use of different methods for this issue.

2. I would include in the methods which were the guiding topics of the focus group and which were the questions of the individual interviews.

3. I would be cautious in generalizing the results to other cultures.

Author Response:

Thank you for this feedback.

1. The decision to undertake both interviews and focus group discussions was a pragmatic one intended to accommodate as many people as possible in the rapid evaluation. We have included the combination of the two forms of data as a limitation in our discussion (p15) “This also meant a range of different qualitative data was collected and analysed together, which must be considered.”

2. The topic guide has now been added as an appendix and a statement has been added to the methods section to clarify that the same topic guide was used for each (p5) “The same topic guide was used for the focus groups, one-to-one interviews and email interviews (Appendix 1).”

3. Thank you – this has now been explicitly stated in the discussion (p15) “However, the applicability of these findings to other cultures would need to be interrogated as the programme took place in and participants were recruited from the UK, a high-income country.”

Reviewer #6:

This is a well-written manuscript.

The study objective is clear and the methods used are appropriate and well detailed.

In my opinion, the revisions made to issues made by previous reviewers are sufficient.

I recommend for acceptance.

Author Response:

Thank you for this feedback.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
