• A copy of your manuscript showing your changes by either highlighting them or using track changes (uploaded as a *supporting information* file)
• A clean copy of the edited manuscript (uploaded as the new *manuscript* file)

3. In your Data Availability statement, you have not specified where the minimal data set underlying the results described in your manuscript can be found. PLOS defines a study's minimal data set as the underlying data used to reach the conclusions drawn in the manuscript and any additional data required to replicate the reported study findings in their entirety. All PLOS journals require that the minimal data set be made fully available. For more information about our data policy, please see http://journals.plos.org/plosone/s/data-availability.

Upon re-submitting your revised manuscript, please upload your study’s minimal underlying data set as either Supporting Information files or to a stable, public repository and include the relevant URLs, DOIs, or accession numbers within your revised cover letter. For a list of acceptable repositories, please see http://journals.plos.org/plosone/s/data-availability#loc-recommended-repositories. Any potentially identifying patient information must be fully anonymized.

Important: If there are ethical or legal restrictions to sharing your data publicly, please explain these restrictions in detail. Please see our guidelines for more information on what we consider unacceptable restrictions to publicly sharing data: http://journals.plos.org/plosone/s/data-availability#loc-unacceptable-data-access-restrictions.

Reviewer's Responses to Questions

Comments to the Author

1. Does the manuscript provide a valid rationale for the proposed study, with clearly identified and justified research questions?

The research question outlined is expected to address a valid academic problem or topic and contribute to the base of knowledge in the field.

Reviewer #1: Yes

Reviewer #2: Partly

**********

2. Is the protocol technically sound and planned in a manner that will lead to a meaningful outcome and allow testing the stated hypotheses?

The manuscript should describe the methods in sufficient detail to prevent undisclosed flexibility in the experimental procedure or analysis pipeline, including sufficient outcome-neutral conditions (e.g. necessary controls, absence of floor or ceiling effects) to test the proposed hypotheses and a statistical power analysis where applicable. As there may be aspects of the methodology and analysis which can only be refined once the work is undertaken, authors should outline potential assumptions and explicitly describe what aspects of the proposed analyses, if any, are exploratory.

Reviewer #1: Yes

Reviewer #2: Yes

**********

3. Is the methodology feasible and described in sufficient detail to allow the work to be replicable?

Reviewer #1: Yes

Reviewer #2: Yes

**********

4. Have the authors described where all data underlying the findings will be made available when the study is complete?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception, at the time of publication. The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: No

Reviewer #2: Yes

**********

5. Is the manuscript presented in an intelligible fashion and written in standard English?

PLOS ONE does not copyedit accepted manuscripts, so the language in submitted articles must be clear, correct, and unambiguous. Any typographical or grammatical errors should be corrected at revision, so please note any specific errors here.

Reviewer #1: Yes

Reviewer #2: Yes

**********

6. Review Comments to the Author

Please use the space provided to explain your answers to the questions above and, if applicable, provide comments about issues authors must address before this protocol can be accepted for publication. You may also include additional comments for the author, including concerns about research or publication ethics.

You may also provide optional suggestions and comments to authors that they might find helpful in planning their study.

(Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Review for minor grammar and spelling errors.

Reason for "major review" selection: Include a discussion at the end for the potential impact of the scoping review on the field. This is important to include.

Remove info on how data will be collected in the “aim of study” section. This more appropriately belongs in “methods.”

Include the visual you discussed about the study selection process, inclusion, and exclusion.

PSW or PSWs? In some sentences, plural seems to fit in better with certain sentences and grammar.

Spell out all acronyms the first time you use them (United Nations, line #65).

Need to describe where data will be made available when the study is complete.

Include clear dates of articles included in study. Currently says from inception to 8.31.2020, but that you will update again 1.4.2021. Does that mean that your search will include items that are published up until January 2021? Or will the search only go up until the end of August 2020? Also define what inception is. Is it the start of the journal, etc.?

Reviewer #2: Thank you for the opportunity to review this Registered Report Protocol that aims to examine the influence of peer support worker integration on co-production and co-creation in public health and addictions services. This is an interesting study with some important research questions. It is very important to understand how peer support workers are integrated into co-production and co-creation processes in health system. My comments are below regarding this manuscript:

1. Abstract is not traditional written, which is fine. I see authors report background and method. Final sentence in abstract is research question. I believe abstract will be improved if authors add a one or two sentence/s regarding any expected results and and how these results will inform field.

2. Although authors defined co-creation and co-production, It is still difficult to understand the difference between co-creation and co-production. The distinction between co-creation and co-production could be explained with an example.

3. Second paragraph in introduction has some parts that could be moved to purpose of study. For example, line 93 and rest is about purpose of study. Interestingly, in "Aim of the Study" section authors talk about background again. I suggest authors to move all background information into introduction section. I also suggest authors have a brief and concise purpose of study.

4. There are too many questions in introduction. It is very hard to overall understand introduction due to all questions and how introduction is organized. I suggest authors to be more concise with purpose section and improve background section.

5. I wonder whether this following sentence should move to Method: "The data will be collected based on Arkzey and O'Malley's framework (10): 1) identify the research questions, 2) search for relevant studies, 3) select studies, 4) chart the data, and 5) collate, summarize and report studies."

6. What year period authors aim to conduct this study? Any time restriction such as from 2010 to 2020.

7. In any disagreement, what is the plan? I see authors reported that they will have discussion on disagreement to resolve it. What will be the focus of discussion? What is further step if there is no resolution? For example, do authors plan to bring a third reviewer to help resolution.

8. I see that editorials, reports, and opinion papers will be removed. Later, in "Information on the Following Categories....", item 4 has opinion papers and others.

Thank you for letting me review this Registered Report Protocol. This study seems to be an interesting and informing study.
