Dear Dr. Rater,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Reviewer #1: Introduction- Well-researched and evidence-based.Provides important context on migration and perinatal mental health.Clear identification of a meaningful research aim.

Methodology: appropriately positioned for exploring the deeply personal, identity-based and culturally situated experiences of migrant mothers with postnatal depression (PND). Well written, ethically robust, and grounded in appropriate qualitative and phenomenological principles.

Analysis- The narrative is compelling, the themes are coherent, and the use of participant quotations is strong.

Limitations The analysis does not sufficiently acknowledge how the researcher’s background, assumptions or interpretative lens shaped the analytic process. A reflexivity section is recommended, detailing:

researcher positionality

emotional and cognitive responses during analysis

potential biases

steps taken to mitigate interpretative influence

Discussion, conclusion, limitations- Deep, thoughtful integration of participants’ experiences with theory.

Transparent limitations and clear recommendations for future research

Reviewer #2: Good topic.

If possible try to take more samples for reliable results.Also addition of Gantt chart is advisable for qualitative studies.

Minor corrections required in terms of samle size calculation and minimum sample size numbers.

Reviewer #3: The manuscript is written well, with a very good explanation of IPA. However, it lacks specificity as mentioned in the attached file. Data and tools are not available (as off now) to understand the data collection flow and validity. The authors could revise the manuscript as suggested and provide the access to study tool (interview guide) and the qualitative data for a better understanding.

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. For studies involving human research participant data or other sensitive data, we encourage authors to share de-identified or anonymized data. However, when data cannot be publicly shared for ethical reasons, we allow authors to make their data sets available upon request. For 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. Please see http://www.bmj.com/content/340/bmj.c181.long for guidelines on how to de-identify and prepare clinical data for publication. 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.

Please update your Data Availability statement in the submission form accordingly.

3. Please include your full ethics statement in the ‘Methods’ section of your manuscript file. In your statement, please include the full name of the IRB or ethics committee who approved or waived your study, as well as whether or not you obtained informed written or verbal consent. If consent was waived for your study, please include this information in your statement as well.

4. Please include captions for your Supporting Information files at the end of your manuscript, and update any in-text citations to match accordingly. Please see our Supporting Information guidelines for more information: http://journals.plos.org/plosone/s/supporting-information....

5. We note that there is identifying data in the Supporting Information file < aLMS PGR UH 05737(1) Rater L 19000424 Notification (1) and aLMS PGR UH 05737 Rater L 19000424 Notification>. Due to the inclusion of these potentially identifying data, we have removed this file from your file inventory. Prior to sharing human research participant data, authors should consult with an ethics committee to ensure data are shared in accordance with participant consent and all applicable local laws.

Data sharing should never compromise participant privacy. It is therefore not appropriate to publicly share personally identifiable data on human research participants. The following are examples of data that should not be shared:

-Name, initials, physical address

-Ages more specific than whole numbers

-Internet protocol (IP) address

-Specific dates (birth dates, death dates, examination dates, etc.)

-Contact information such as phone number or email address

-Location data

-ID numbers that seem specific (long numbers, include initials, titled “Hospital ID”) rather than random (small numbers in numerical order)

Data that are not directly identifying may also be inappropriate to share, as in combination they can become identifying. For example, data collected from a small group of participants, vulnerable populations, or private groups should not be shared if they involve indirect identifiers (such as sex, ethnicity, location, etc.) that may risk the identification of study participants.

Additional guidance on preparing raw data for publication can be found in our Data Policy (https://journals.plos.org/plosone/s/data-availability#loc-human-research-participant-data-and-other-sensitive-data) and in the following article: http://www.bmj.com/content/340/bmj.c181.long.

Please remove or anonymize all personal information (Name), ensure that the data shared are in accordance with participant consent, and re-upload a fully anonymized data set. Please note that spreadsheet columns with personal information must be removed and not hidden as all hidden columns will appear in the published file.

6. If the reviewer comments include a recommendation to cite specific previously published works, please review and evaluate these publications to determine whether they are relevant and should be cited. There is no requirement to cite these works unless the editor has indicated otherwise.

7. 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.

Reviewer #2: The manuscript addresses an important and underexplored topic—experiences of postnatal depression (PND) among voluntary migrant mothers in the UK—using an appropriate qualitative approach. The use of Interpretative Phenomenological Analysis is well-justified and aligns with the study’s aim of capturing lived experiences. The themes are rich, coherent, and supported by illustrative participant quotes, enhancing credibility and depth.

However, several areas require improvement. First, the sample size (n=7), while acceptable for IPA, limits transferability; the authors should better justify sample adequacy and discuss saturation more explicitly. Second, there is limited diversity in the sample (predominantly White participants), which restricts representation of more vulnerable migrant groups—this should be more critically reflected upon. Third, while reflexivity is well-described, the potential influence of researcher positionality on theme development could be more explicitly linked to findings.

The methodology section would benefit from clearer details on recruitment (e.g., response rate) and how rigor was ensured (e.g., triangulation, audit trail). Additionally, the data availability statement does not fully align with journal requirements and may need revision.

Overall, the study is meaningful and publishable.

Reviewer #3: All comments have been addressed. Regarding data availability, authors mentioned that disclosing the anonymous qualitative transcripts is not possible due to potential ethical violation, which is acceptable.

However, inserting page numbers in the submitted document would have been better to track the modifications made more easily.
