* The comprehensive details regarding the ethical principles to be adhered to by our authors, reviewers, and editors, as well as our publication policy, are accessible at https://dergipark.org.tr/tr/pub/tjph/policy.

Turkish Journal of Public Health is a member of Committee on Publication Ethics (COPE) and accepts its publication ethics principles and evaluates all submitted manuscripts within this scope. Readers and authors can access these rules and case samples via below links:

https://publicationethics.org/guidance/Guidelines , https://publicationethics.org/guidance/Flowcharts
https://publicationethics.org/guidance/Case.
Main issues of publication ethics have been listed below:

Human and Animal Rights

For the experimental, clinical, and drug human studies, approval by the ethical committee and a statement on the adherence of the study protocol to the international agreements (World Medical Association of Helsinki "Ethical Principles for Medical Research Involving Human Subjects," amended October 2013) are required. In experimental animal studies, the authors should indicate that the procedures followed were by animal rights (Guide for the care and use of laboratory animals), and they should obtain animal ethics committee approval. The Ethics Committee approval document should be submitted to the Turkish Journal of Public Health together with the manuscript.
The approval of the ethics committee; a statement on the adherence to international guidelines mentioned above; and proof that the patient's informed consent is obtained should be indicated in the $Material\text{and}Method$ section. These items are required for case reports whenever data/media could reveal the identity of the patient.
For persons under 18 years of age, please provide a consent form that includes both parents' signatures or of the person's legal guardian or supervisor.

Plagiarism and other violations

The quality of data and analysis presented are important issues for Turk J Public Health. The authors must provide the data sets upon the requests from the editors for review. Editors in Turk J Public Health check the text contents for plagiarism and duplication by using related software. By submitting your manuscript to this journal authors accept that the manuscript may be screened for plagiarism against previously published works. If plagiarism is detected before publication, manuscript will be rejected and would be subjected to institutional acknowledgment of the author(s). This information might send to the institutions of the authors as well as the other relevant institutions. Turk J Public Health does not accept any manuscript that has already been submitted to another journal for evaluation and/or articles previously published. Therefore, the authors must be sure and declare that the manuscript has not been submitted concomitantly to any other journal in the cover letter.

Disclosure and Conflicts of Interest

All sources of financial support should be disclosed. All authors should disclose if a conflict of interest exists in the process of forming their study. Any financial grants or other support received for a submitted study from individuals or institutions should be disclosed to the Editorial Board of the Turkish Journal of Public Health. The ICMJE Potential Conflict of Interest Disclosure Form should be filled in and submitted by all contributing authors to disclose a potential conflict of interest. The journal's Editorial Board determines cases of a potential conflict of interest of the editors, authors, or reviewers within the scope of COPE and ICMJE guidelines.
Conditions that provide financial or personal benefit bring about a conflict of interest. The reliability of the scientific process and the published articles is directly related to the objective consideration of conflicts of interest during the planning, implementation, writing, evaluation, editing, and publication of scientific studies.
Financial relations are the most easily identified conflicts of interest, and it is inevitable that they will undermine the credibility of the journal, the authors, and the science. These conflicts can be caused by individual relations, academic competition, or intellectual approaches. The authors should refrain as much as possible from making agreements with sponsors in the opinion of gaining profit or any other advantage that restrict their ability to access all data of the study or analyze, interpret, prepare, and publish their articles. Editors should refrain from bringing together those who may have any relationship between them during the evaluation of the studies. The editors, who make the final decision about the articles, should not have any personal, professional, or financial ties with any of the issues they are going to decide. Authors should inform the editorial board concerning potential conflicts of interest to ensure that their articles will be evaluated within the framework of ethical principles through an independent assessment process.
If one of the editors is an author in any manuscript, the editor is excluded from the manuscript evaluation process. In order to prevent any conflict of interest, the article evaluation process is carried out as double-blinded. Because of the double-blinded evaluation process, except for the Editor-in-Chief, none of the editorial board members, international advisory board members, or reviewers is informed about the authors of the manuscript or institutions of the authors.
Our publication team works devotedly to ensure that the evaluation process is conducted impartially, considering all these situations.

Authorship and its declaration

We adhere to the criteria of the International Committee of Medical Journal Editors (JAMA. 1997; 277:927-934). For manuscripts with two or more authors, each author must qualify by having participated actively and sufficiently in the study that is being carried out and reported on. The inclusion of each author in the authorship list of a manuscript is based only:
a. On substantial contributions to (1) concepts and design, or analysis and interpretation of data and (2) drafting the manuscript or revising it critically for important intellectual content; and; b. On final approval by each author of the submitted version of the manuscript.
Conditions “a” (1 and 2) and “b” must both be met. Others contributing to the work should be recognized separately in an Acknowledgement. In the covering letter that accompanies the submitted manuscripts, it must be confirmed that all authors fulfilled both conditions.

Authorship of Editors

The peer review process is confidential to all parties in Turk J Public Health. Editors in chief are not allowed to submit their papers except editorials because the anonymity cannot be ensured for evaluation process. Section editors, on the other hand, can submit their manuscript to Turk J Public Health . The manuscripts of the section editors are subjected to anonymous peer review like the other authors' papers. Chief Editors and the section editors are required to notify the management of the Journal if there have been any conflicts of interest between them. Managers cannot make suggestions and/or pressure to the editors about the manuscripts submitted to the Turk J Public Health. Manuscripts should be submitted for consideration only after written consent is given by all contributing authors. The list of authors should include all those, who can claim authorship in accordance with the authorship policies of ICMJE and COPE.

Ethics Committee Approval and Consents

Studies with the participation of human subjects should state both the ethical approval and the type of consent that was received in the methods section of manuscript. If ethical approval has not been obtained, that should also be declared.

Artificial Intelligence (AI) Use Policy for Authors

Turkish Journal of Public Health – Author Guidelines Addendum

In line with the principles and recommendations of the Committee on Publication Ethics (COPE), the Turkish Journal of Public Health (TJPH) recognizes the increasing use of Artificial Intelligence (AI) tools in academic writing and research. However, the use of AI must comply with ethical publishing standards to ensure transparency, accountability, and integrity.
Authors are therefore required to adhere to the following rules:
1. AI Tools Cannot Be Listed as Authors
TJPH follows COPE’s position that AI tools cannot fulfill the role of an author, and therefore cannot be listed as authors in any submission. Only individuals who meet authorship criteria (e.g., substantial contribution, accountability, and approval of the final version) should be named as authors.
2. Disclosure of AI Use Is Mandatory
“Authors who use AI tools in the writing of a manuscript, production of images or graphical elements of the paper, or in the collection and analysis of data, must be transparent in disclosing in Methods section and cover letter of the paper how the AI tool was used and which tool was used."
The following format may be used in cover letter:
"During the preparation of this manuscript, the authors used [Tool Name, e.g., ChatGPT, OpenAI] for [specific purpose, e.g., language editing, drafting parts of the introduction, summarizing background literature]. After using this tool, the authors reviewed and edited the content as needed and take full responsibility for the content of the publication."
Undisclosed or unethical use of AI may lead to rejection of the manuscript or retraction of the published article.
This policy will be periodically reviewed and updated in line with COPE guidance and evolving best practices.
For any questions regarding the use of AI tools, please contact the editorial office prior to submission.

Guideline for Section Editors and Peer Reviewers
1. Purpose and Scope
This document provides ethical and procedural guidance for Section Editors and Peer Reviewers of the Turkish Journal of Public Health (TJPH), consistent with the principles of the Committee on Publication Ethics (COPE).
It aims to safeguard the integrity, confidentiality, and fairness of the editorial and peer review process, define appropriate and transparent use of Artificial Intelligence (AI) tools in editorial and review workflows, and promote accountability, transparency, and trust in scholarly publishing.
2. Fundamental Ethical Principles
• Integrity: Decisions must be based solely on the scientific merit of the work, independent of personal, institutional, or commercial interests.
• Accountability: Editors and reviewers remain fully responsible for decisions and judgments, even when assisted by software or AI tools.
• Confidentiality: Unpublished material must not be disclosed or used for personal advantage.
• Transparency: Use of AI systems must be declared, traceable, and limited to ethically acceptable purposes.
• Fairness and Impartiality: Reviews and editorial decisions must be free from bias related to authors’ gender, nationality, institutional affiliation, or research field.
3. Responsibilities of Section Editors
• Editorial Oversight and Decision-Making
• Section Editors are responsible for ensuring a fair and timely peer review process. Final decisions on acceptance or rejection of manuscripts must always be made by a human editor. No AI tool may autonomously determine manuscript outcomes. Editors must evaluate AI-generated recommendations critically and ensure human oversight in every step of the decision process.
• Use of AI Tools
• Editors may use AI-assisted tools only for supportive functions, such as reviewer matching, plagiarism detection, or language checks. AI tools must not be used for making final editorial decisions, generating decision letters, or evaluating novelty and validity without human judgment.
• Confidentiality and Data Protection
Editors must not upload manuscripts or reviewer comments to public or non-secure AI systems.
• Accountability and Transparency
Editors remain accountable for all outcomes of AI-assisted decisions. Any use of AI in editorial workflows must be disclosed internally and traceable. Editors must justify all decisions, including AI-supported analyses.
• Managing Ethical Concerns
Editors must act promptly when ethical issues are identified. AI outputs suggesting ethical breaches should be verified manually before action is taken, following COPE’s procedures.
4. Responsibilities of Peer Reviewers
• Reviewers should accept invitations only if they have the necessary expertise and can complete the task impartially and on time.
• Manuscripts under review are confidential and must not be shared or uploaded to AI tools.
• Reviewers may use AI only for language or grammar assistance and must disclose any such use in their review.
• Reviewers must provide objective, constructive, and respectful feedback, focusing solely on scientific merit.
• If ethical misconduct is suspected, reviewers should report it confidentially to the Section Editor without public accusations.
5. Handling of AI-Related Issues
If a reviewer or editor suspects that AI tools were misused in manuscript preparation, review, or decision-making, they should report the concern confidentially to the Editor-in-Chief.
TJPH will maintain records of AI-related incidents and update policies accordingly.
6. Transparency Toward Authors
Authors have the right to know whether AI-assisted systems were involved in manuscript handling (e.g., plagiarism checks, reviewer matching).
Any AI use in decision support should be described transparently in the journal’s editorial policies.
This guideline will be reviewed annually based on new COPE or other recommendations and technological developments.
