Guidelines and Policies



  • BrJP accepts the submission of preprints. A preprint is defined as a complete and finalized manuscript for submission to a journal that is deposited on a trusted preprint server, before or in parallel to submission to a journal.

  • A trusted preprint server must have a transparent moderation policy, offer DOI to submitted preprints, allow changes to the preprint version, comments and community evaluation with researcher endorsement and interoperability with other services and platforms. Only submissions of work previously deposited on public server platforms that meet these characteristics of reliability and transparency will be accepted.

  • The public platforms PreprintsSciELO Preprints and EmeRI are recommended for open discussion before approval and publication in the journal.

  • In the event of acceptance and publication of the article in BrJP, it is the responsibility of the authors to update the registration on the preprint server, informing the full reference of the publication in the journal.

Peer review process

  • Pre-Analysis: all manuscripts submitted to BrJP will be sent to the Editor-in-Chief. The Editor-in-Chief will be responsible for assessing and verifying that the potential publication is appropriate to the scope of the journal. Manuscripts that do not meet all the methodological and ethical requirements as well as the authenticity statement will be subject to analysis by a plagiarism software, using the iThenticate originality detection service. Manuscripts that do not meet these criteria will be rejected and returned to the authors at this stage. Manuscripts deemed appropriate by the editor are then sent for technical evaluation.

  • Technical evaluation: this stage verifies compliance with the publication and documentation standards required when submitting manuscripts to BrJP. In the event of non-compliance with the instructions, the manuscript will be returned to the authors for adjustments. Only after the required documentation has been complied with will the manuscript be assigned by the Editor-in-Chief to an Associate Editor in the manuscript's main subject area. From this stage onward, the Associate Editor assumes responsibility for processing and evaluating the manuscript, and his/her name will be identified in the process.

  • Assessment of relevance and contribution to the scope of BrJP: carried out by the Editor-in-charge. At this stage, the article may be returned to the authors for not meeting the criteria of relevance and contribution, or it may be forwarded to the referees.

  • Merit and content analysis: after the manuscript has been assessed by the Editor-in-charge, the article is then evaluated for merit and scientific method by at least two ad hoc evaluators/reviewers from units other than the one where the work originated. The reviewers can recommend four options: "accepted", "accepted with minor corrections", "reconsider after extensive review" or "reject the manuscript". The Editor-in-Chief will also carry out an analysis of merit and content. At this stage, the Editor-in-charge and Editor-in-chief offer the referees the option of talking directly to the corresponding author, with or without revealing their identity.

  • Final decision: It is up to the Editor-in-Chief to decide whether to accept the manuscript. Whenever necessary, a revision of the original article will be requested and the manuscript will be returned to the corresponding author for adaptation. A revised version with the changes made must be submitted by the authors and this will be re-evaluated by the Editor-in-Chief, Associate Editors and reviewers as necessary. When approved, the name of the Associate Editor responsible for processing the manuscript will be published in the article with their OCID, under the nomenclature "Editor in charge".

  • After approval: Manuscripts approved as to their scientific merit for publication in BrJP will be sent for translation into English or Portuguese. After translation, the articles in bilingual format will be sent to the layout designer and sent in PDF format to the authors for final approval before publication. The authors will have 48 hours to send in any minor changes, correct spelling and check the illustrations. It should be noted that any extensive modifications will imply re-examination by the reviewers and will cause a delay in the publication of the work. All articles will have a DOI record.

  • Suggestion: BrJP encourages the option of publishing article approval reports with or without identifying the reviewers. Opinions constitute a new type of literature in the SciELO methodology and receive similar treatment to research articles, according to the Open Science Compliance Form completed by the authors when submitting the manuscript.

Open data

  • As a good practice, following Open Science to ensure security and transparency, the BrJP encourages the "sharing of data, codes, methods and other materials used and resulting from research that generally underlie the texts of articles published by journals”.

  • Research data from the manuscript approved for publication in BrJP can be stored in the Scielo Data / BrJP repository

  • The manuscript must provide a descriptive caption for each supplementary material published and the final layout of the article will contain a link to the data repository.

  • It is recommended to store data observed, collected, generated to validate the results of the original research, whether raw data, processed data, audio, video, code, software, algorithms, protocols and methods.

Fees charged

  • There is no charge to authors for submitting or processing articles (APC).

  • Financial sustainability is the responsibility of the Brazilian Society for the Study of Pain and its partners/sponsors through annual or bi-annual contracts.

Ethics and Misconduct Policy, Errata and Retraction

  • BrJP adopts the principles of publication ethics included in the code of conduct of the Committee on Publication Ethics (COPE). Ethical issues and/or those that could damage the journal's reputation will be evaluated and retracted by the BrJP editorial board and the board of the Brazilian Society for the Study of Pain. 

  • In the event of misconduct, the retraction policy will be applied by the journal, in accordance with the Good Practices Guide proposed by SciELO.

  • Registration and Errata Publication will follow the recommendations proposed by SciELO.

  • Retraction registration and publication will be as proposed by SciELO.

Conflict of Interests Policy

  • Conflicts of interest can be of a personal, commercial, political, academic or financial nature. Conflicts of interest can occur when authors, reviewers or editors have interests that may influence the preparation or evaluation of manuscripts. 

  • Authors, reviewers and editors involved in the manuscript evaluation and processing process must disclose a summary declaration of interest in the title page file. If there is no interest to declare, then it should be stated: "Declarations of interest: none". This declaration will ultimately be published if the article is accepted. 

  • The reviewers and editors involved in the process must disclose in a declaration whether or not there is a conflict of interest involved in the process of evaluating and processing the article. If there is, even if it is a potential conflict, the conflict of interest must be disclosed in a signed document attached to the processing file. This information will be published if the article is approved.

  • All authors, reviewers and editors involved in the article evaluation and processing process must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential competing interests include employment, consulting, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding.

  • When editors have a conflict of interest, they should delegate decision-making to other editors.

Adoption of similarity checking software

  • BrJP uses the iThenticate similarity checking software from the CrossRef platform.

  • Manuscripts are analyzed for similarity before being sent to reviewers. When extensive changes are made in the process of evaluating the manuscript, editors and reviewers may suggest a new check, in which case the article will undergo a new similarity check.

Sex and Gender Issues

  • The BrJP editorial team, as well as the authors who publish in the journal, must always observe the Sex and Gender Equity in Research (SAGER) guidelines. The SAGER guidelines comprise a set of guidelines for reporting sex and gender information in study design, data analysis, results and interpretation of findings. In addition, BrJP observes the gender equity policy in the formation of its editorial board.

Ethics Committee

  • ·When the research article involves procedures with human beings, animals or LGPD-sensitive data (LGPD - General Personal Data Protection Law), the authors must attach a statement of approval from the ethics committee of the institution responsible for approving the research.

The primary goal of a graphical abstract is to provide readers with a quick and clear overview of the article's content, helping them understand the study's essence and decide whether to read the full article. This visual summary is particularly valuable in scientific fields where rapid and effective communication of findings is crucial. A graphical abstract may include elements such as graphs, illustrations, diagrams, symbols, and concise text to highlight the study's key points. It should be designed to capture attention and convey information clearly and succinctly.

  • Introduction: Briefly describe the scope and prior evidence-based knowledge (state of the art) for the research design, based on bibliographic references related to the topic, preferably the most recent as possible.
