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. Thank you for stating the following in the Competing Interests section: 

"I have read the journal's policy and the authors of this manuscript have the following competing interests: Michelle Lofwall has served as a scientific consultant for Berkshire Biomedical, Braeburn, Journey Colab, and Titan Pharmaceuticals in the last three years."

Please confirm that this does not alter your adherence to all PLOS ONE policies on sharing data and materials, by including the following statement: ""This does not alter our adherence to  PLOS ONE policies on sharing data and materials.” (as detailed online in our guide for authors http://journals.plos.org/plosone/s/competing-interests).  If there are restrictions on sharing of data and/or materials, please state these. Please note that we cannot proceed with consideration of your article until this information has been declared. 

Please include your updated Competing Interests statement in your cover letter; we will change the online submission form on your behalf.

3. Please note that in order to use the direct billing option the corresponding author must be affiliated with the chosen institute. Please either amend your manuscript to change the affiliation or corresponding author, or email us at plosone@plos.org with a request to remove this option.

4. In this instance it seems there may be acceptable restrictions in place that prevent the public sharing of your minimal data. However, in line with our goal of ensuring long-term data availability to all interested researchers, PLOS’ Data Policy states that authors cannot be the sole named individuals responsible for ensuring data access (http://journals.plos.org/plosone/s/data-availability#loc-acceptable-data-sharing-methods).

Data requests to a non-author institutional point of contact, such as a data access or ethics committee, helps guarantee long term stability and availability of data. Providing interested researchers with a durable point of contact ensures data will be accessible even if an author changes email addresses, institutions, or becomes unavailable to answer requests.

Before we proceed with your manuscript, please also provide non-author contact information (phone/email/hyperlink) for a data access committee, ethics committee, or other institutional body to which data requests may be sent. If no institutional body is available to respond to requests for your minimal data, please consider if there any institutional representatives who did not collaborate in the study, and are not listed as authors on the manuscript, who would be able to hold the data and respond to external requests for data access? If so, please provide their contact information (i.e., email address). Please also provide details on how you will ensure persistent or long-term data storage and availability.

5. Your ethics statement should only appear in the Methods section of your manuscript. If your ethics statement is written in any section besides the Methods, please delete it from any other section.

6. 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.

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: This is a very interesting study. Kindly see my minor comments below.

1. Why are there so many authors involved in this study?

2. In the methodology section, the study design used is not clearly indicated. Please amend this section to include information on the study design used.

3. Why did you use per-protocol analysis instead of intention-to-treat analysis in your study?

4. From lines 135–39, there are different time points for conducting interviews, i.e., the CEQ timeline, for the intervention group (W1) and comparison group (W2). How could these differences contribute to bias and impact the validity of your result?

5. In line 146, what do you mean by the statement “residents ≥ 18”? If you intend to indicate the inclusion criteria of your study participants as “residents ≥ 18 years," please amend it to reflect the proposed change.

6. In Line 183, the statement “Higher response scores suggested less belief in efficacy regarding OUD treatment” is not clear. The given 5-point Likert scale from 1 (strongly agree) to 5 (strongly disagree) for the item stated, “Once you have an opioid addiction or opioid use disorder, there’s not much you can do about it,” indicated that the higher response scores suggested a higher belief in efficacy regarding OUD treatment. Kindly provide explanations for this observation or amend it accordingly to be in line with the proposed 5-point Likert scale. A similar observation was seen in lines 184–87.

7. In the result section, why were only 63 communities included in Table 1 for baseline data (CEQ1) instead of 66 communities?

The overall quality of English is good, but language and grammar edits can further strengthen the manuscript.

Reviewer #2: The title of the article can be trimmed a little, it is 23 word titles can be reduced to 20 or less. The data is not made available but explanation is given as to why, which is understandable. The article will add to the body of knowledge.

Revision 1

July 1, 2024

Dear Dr. Kamran,

Thank you for the opportunity to revise and resubmit our manuscript: “How do stigma and efficacy beliefs regarding opioid use disorder treatment and naloxone change in communities participating in the HEALing Communities Study intervention?,” now shortened to: “Stigma and efficacy beliefs regarding opioid use disorder treatment and naloxone in communities participating in the HEALing Communities Study intervention.” The reviewer comments were considered at length, and new versions of the manuscript have been submitted to the Author Center (one marked and one unmarked). Please see a point-by-point response to the reviewer comments below.

From Reviewer 1:

This is a very interesting study. Kindly see my minor comments below.

Thanks to Reviewer 1 for their support of our manuscript.

1. Why are there so many authors involved in this study?

This is a fair question. The HEALing Communities Study (HCS) is the largest implementation science study ever conducted in addiction research and included 67 communities across 4 states. Our large multi-site, interdisciplinary teams included faculty, staff, and community members from multiple domains (e.g., communication, community engagement, statistics, clinical trials, opioid use disorder treatment and overdose prevention prevention). Our commitment to team science, valuing site members and including contributions by community members, was a priority for this and all other HCS manuscripts.

2. In the methodology section, the study design used is not clearly indicated. Please amend this section to include information on the study design used.

We added additional content to clarify the study’s design. The first sentence of the methods section (p. 6) now describes the study as a longitudinal comparison of communities within the context of a cluster randomized trial. We also included a sentence at the top of p. 6 explaining that recruitment via social media served as a tool to assess recognition and impact of the campaigns. In the middle of p. 7, we added an additional note that the CEQ study utilized a convenience sample. If there is additional information we should add about the HCS and the CEQ, we would be happy to do so.

3. Why did you use per-protocol analysis instead of intention-to-treat analysis in your study?

Per-protocol analysis was used instead of intention-to-treat analysis because one community was randomized but dropped out before the intervention began. This community was randomized to the intervention arm (W1) but never had exposure to any of the communication campaigns, or other aspects of the HCS intervention. A sentence has been added to the bottom of p. 6 explaining that one community withdrew immediately after randomization, was not treated as randomized, and excluded from further analysis.

4. From lines 135–39, there are different time points for conducting interviews, i.e., the CEQ timeline, for the intervention group (W1) and comparison group (W2). How could these differences contribute to bias and impact the validity of your result?

Indeed, W2 only had data collection at certain time points compared to W1. However, the different time schedules for the CEQ between the waves should not cause any biases because in cases where analysis involved a comparison between W1 and W2, those analyses only included CEQ data from timepoints where they were collected from both Waves (CEQs 1, 4, and 6). Data from CEQs 2, 3, and 5 were only used in analysis involving Wave 1.

5. In line 146, what do you mean by the statement “residents ≥ 18”? If you intend to indicate the inclusion criteria of your study participants as “residents ≥ 18 years," please amend it to reflect the proposed change.

Thanks to Reviewer 1 for catching this. This line has now been changed to add ‘years’ after 18.

6. In Line 183, the statement “Higher response scores suggested less belief in efficacy regarding OUD treatment” is not clear. The given 5-point Likert scale from 1 (strongly agree) to 5 (strongly disagree) for the item stated, “Once you have an opioid addiction or opioid use disorder, there’s not much you can do about it,” indicated that the higher response scores suggested a higher belief in efficacy regarding OUD treatment. Kindly provide explanations for this observation or amend it accordingly to be in line with the proposed 5-point Likert scale. A similar observation was seen in lines 184–87.

We see where this wording could be confusing. The wording has been amended to read correctly at the bottom of p. 8 and at the top of p. 9. The original version of the manuscript included incorrect wording but had no effect on the interpretation of the analyses.

7. In the result section, why were only 63 communities included in Table 1 for baseline data (CEQ1) instead of 66 communities?

The CEQ was a survey sent out via social media, so it is possible that no one from a particular community clicked on the link during a specific CEQ. As such, CEQ1 only had 63 communities represented by participants. Alternatively, CEQ4 had all 66 communities represented by participants.

The overall quality of English is good, but language and grammar edits can further strengthen the manuscript.

We have conducted an additional review of language and grammar to ease readability.

Our thanks again to Reviewer 1 for their thoughtful critique and comments on our manuscript.

From Reviewer 2:

The title of the article can be trimmed a little, it is 23 word titles can be reduced to 20 or less. The data is not made available but explanation is given as to why, which is understandable. This article will add to the body of knowledge.

We agreed with Reviewer 2 that the title could be shortened. It is now 20 words. Thanks also to Reviewer 2 for their positive feedback on our manuscript.

We greatly appreciate the Editor and Reviewers for taking the time and effort to thoughtfully review our manuscript. Thank you again for considering this manuscript for publication in PLOS ONE.
