Before submission
The lead author must ensure that:

  • A corresponding author is identified to be the point of contact with the journal throughout the process
  • The submission is original work
  • Any previously published extracts that are included in the manuscript are fully cited with permission
  • This work is not under consideration by another journal or conference, or has been published previously by another journal or in conference proceedings
  • The work will not be publicised or published elsewhere
  • Any interests that could impair the credibility of the manuscript are disclosed in the cover letter to the Editor, to be uploaded with the submission
  • Authorship conforms to the International Committee of Medical Journal Editors (ICMJE) criteria
  • If the manuscript is reporting a clinical trial, the trial conforms to ICMJE recommendations

Authorship
The IJPDS adheres to the ICMJE’s 4 criteria of authorship: http://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html. To gain credit as an author, each of these criteria needs to be met.  Each author is accountable for their own contribution, and any person meeting these four criteria should be listed as an author.  The responsibility of identifying who meets the criteria falls on authors (and not the journal). The lead and co-authors shall hold harmless Swansea University and the IJPDS as to warranties and representations of the author's ownership, originality, or similar breaches. Such indemnification shall last beyond publication of the article, as well as extend to all related claims. Other contributions that do not meet the criteria should be acknowledged, with permission of the contributor.  Email confirmation of submission will be sent to each author, and any changes to authorship once the manuscript has been submitted must be notified to the journal with an explanation.

Clinical trials
In accordance with ICMJE recommendations, the IJPDS will only consider publication of clinical trials if the trial was registered with a public trials registry at or before the time of first patient enrolment (i.e. the time of first patient consent).  An acceptable registry must include the minimum 20-item trial registration dataset:

(http://prsinfo.clinicaltrials.gov/trainTrainer/WHO-ICMJE-ClinTrialsgov-Cross-Ref.pdf or www.who.int/ictrp/network/trds/en/index.html) at the time of trial registration and before enrolment of the first participant.  Secondary analyses of trials should not be registered as a separate trial; instead submissions of this type should include the trial registration number of the original trial.

The online submission system
The submitting author needs to be registered with the online submission system.  This is done by creating a user name and password and entering some personal details.  Please refer to the privacy policy for further information.  The online submission system will guide you stepwise through the process, and you will be able to check the status of your manuscript at any time.

Manuscripts should be uploaded in an editable format: an OpenOffice, Microsoft Word or RTF document. If you are unable to use one of these formats please contact the journal for advice. If accepted, the manuscript will be published in a non-editable format and allocated a DOI number.  Text must be single-spaced in 12-point font. Italics should be used for emphasis, rather than underlining (except with URL addresses).  Please note that IJPDS uses plagiarism checking software to verify the originality of submitted manuscripts.

All manuscripts must be written in English.  There are no rigid word limits but a typical research article should be between 3000 and 6000 words. The IMRAD format should be followed:

Abstract
Introduction
Methods
Results
Discussion
Conclusion
Acknowledgments
Statement on conflicts of Interest
References
Abbreviations

If the IMRAD format is used inappropriate for the submission, please contact the journal for advice.

All papers must contain an abstract of up to 300 words.  Research articles abstracts should be structured using the headings: introduction, objectives, methods, results (including relevant statistics), and conclusions.  Other types of papers may submit an unstructured abstract.  Please use subheadings beneath main headings in the body of the manuscript.  For example, if a number of different methods have been used, give each of these a separate heading.  The results from each method should also come under its own heading. Longer manuscripts should also include highlights in the form of 3 to 5 bullet points conveying the focus or findings of the article. These should be placed after the abstract.

Studies using observational routinely-collected data should follow the RECORD statement: http://www.equator-network.org/reporting-guidelines/record/. Randomized controlled trials should be reported following the CONSORT statement and include a diagram illustrating the flow of participants through the trial (please see online for CONSORT checklist here: http://www.consort-statement.org/checklists/view/32-consort/66-title). Meta-analyses and systematic reviews should be reported in accordance with the PRISMA statement (PRISMA checklist can be found online here: http://prisma-statement.org/documents/PRISMA%202009%20checklist.pdf).

Covering letter
A covering letter should be included with your submission regardless of manuscript type.  This can be uploaded as a separate file or inserted in the ‘Comments for the Editor’ box.   Please indicate your intended manuscript type.

References
References should be cited in Vancouver style (see ‘Citing Medicine: The NLM Style Guide for Authors, Editors, and Publishers, 2nd edition’: https://www.ncbi.nlm.nih.gov/books/NBK7282/ for guidance).  When available, please provide URLs for references. 

Figures, Tables and Illustrations
Figures, tables and illustrations with legends must be placed within the text at the appropriate points, not at the end of the manuscript.  These must be in portrait format and in 12-point for tables.  When providing tables, please make sure that you create a new table row for each row, rather than have multiple rows in one cell.

You will also have the option of uploading supplementary files as part of your online submission. This could be research instruments (e.g. questionnaires), research materials, research results in full, transcripts, full data analysis, source texts, or other material such as Powerpoint files including screenshots or presentations, graphical/photographic representation of your work, or jpeg versions of conference posters. These must be limited to 1Mb in file size. 

Supplementary appendices intended for publication must be numbered and referred to in the manuscript (e.g. Supplementary Appendix 1).  When these are used, an additional section titled ‘Supplementary Appendices’ should appear in the manuscript before the References section, where appendices should be listed numerically along with a brief description of their content.

Metadata
Please enter the title of the article (and subtitle if relevant) and include keywords in the relevant section.  Terms from the medical subject headings (MeSH) list of Index Medicus should be used (see online: https://www.nlm.nih.gov/mesh/2017/mesh_browser/index.html).  Enter the names of authors and any translators if applicable.  One author must be named as the corresponding author.  Author details should be entered including: title, full name, email address, ORCID number (if available), URL (if applicable) and organisational affiliation.

Ethics
The Committee on Publication Ethics (COPE) addresses issues surrounding breaches of research and publication ethics, and its guidelines define best practice in the ethics of scientific publishing (http://publicationethics.org/resources/code-conduct.  This journal strives to adhere to these guidelines and we encourage authors to refer to them. All submitted research articles must include a statement that the study has obtained ethical approval, including the name of the ethics committee, the ID number of the approval and a statement confirming that participants (if applicable) gave informed consent before participating in the study.  If the study did not require ethical approval, this should be stated along with the reason why this was the case.

Funding
Sources of funding must be declared at the end of the submitted manuscript.  If the funder plays any additional role in the study, for example, in study design or data collection, this should also be noted.   

Conflicts of interest
Conflicts of interest can be personal, commercial, political, academic or financial.  Any actual or potential conflicts of interest must be disclosed by all authors.  If there are no existing conflicts of interest, this will be noted on the published manuscript as ‘None declared’. 

Please check that you have complied with the following:

  1. References are cited consistently and in accordance with journal style
  2. URLs to online references are provided and live
  3. All references mentioned in the Reference list are cited in the text, and vice versa
  4. All tables and figures are referred to in the text
  5. Abbreviations in tables and figures are explained in the table notes and figure captions
  6. (If you are not a native English speaker) the text has been revised using a professional manuscript editing company. All such services are paid for and arranged by the author. Use of one of these services does not guarantee acceptance or preference for publication
  7. Only one space has been entered after the full-stop at the end of a sentence
  8. Italics or ‘single quotes’ have been used for emphasis (avoid using underlines)
  9. The same elements have been keyed in exactly the same way throughout the manuscript

After submission
Once you have completed your submission, you will receive confirmation via email. The corresponding author will take responsibility for the submission as it is being processed, for example, for responding to requests for further information or editorial queries.  However, the editors will send copies of correspondence to all listed authors. Following submission, the manuscript will be assigned to an Editor who will determine whether it is suitable for this journal.  If so, the manuscript will then be sent to be peer reviewed, as appropriate for the type of submission. The Editorial Board reserves the right to choose the reviewers, and reviewer identity will be blinded to authors.  Following peer-review, the Editor will provide feedback to the author, based on the reviewers’ comments and recommendations. These might be to: accept, request minor revisions to, request major revisions to, or reject the manuscript. At this point, the manuscript will be returned to the corresponding author for response. The Editor will make a final decision based on the authors’ response.

Fee structure
Publishing with IJPDS is currently free of charge, and this will be the case until 31st December 2017 after which time it will be reviewed.  In future fees will vary with type of submission. Please contact the journal for further details if required.

Corrections, Retractions, Republications and Version Control
If a correction is necessary after publication, this must to be notified to the journal promptly.  We will then endeavour to publish a correction notice as soon as possible. If the corrections are significant enough to warrant a retraction of the article, republication may be possible at the discretion of the Editorial Board. In such cases a new version of the corrected article may be published, detailing the changes made, and any prior versions of the article archived.
