    1. What we Publish

    1.1 Aims & Scope

    Before submitting your manuscript to JPPA, please ensure you have read the Aims & Scope.

    1.2 Fairness and Equal Opportunity

    The National Psoriasis Foundation (NPF) advocates for improved access to care and meaningful access to treatments for all. JPPA supports fairness and equal opportunity in wider society through our publishing activities. There is no discrimination (i.e., age, ethnicity, gender, ability, social class, socioeconomic status, sexual orientation, gender identity, primary spoken language, and geographic region) regarding our editorial board, peer reviewers, and author base.

    1.2.1 Use of inclusive language

    Inclusive language acknowledges diversity, conveys respect to all people, is sensitive to differences, and promotes equal opportunities. Content should make no assumptions about the beliefs or commitments of any reader; contain nothing which might imply that one individual is superior to another on the grounds of age, gender, race, ethnicity, culture, sexual orientation, disability, or health condition; and use inclusive language throughout. Authors should ensure that writing is free from bias, stereotypes, slang, reference to dominant culture and/or cultural assumptions. Avoid the use of descriptors that refer to personal attributes such as age, gender, race, ethnicity, culture, sexual orientation, disability, or health condition unless they are relevant and valid. Refer to the current AMA style guide on race and ethnicity for a complete discussion and examples. These guidelines are meant as a reference to help identify appropriate language but are not exhaustive or definitive. Please see the full AMA Manual of Style for more information.

    1.2.2 English Language Editing Services

    Authors seeking assistance with English language editing, translation, or figure and manuscript formatting to fit the journal’s specifications should consider using Sage Language Services. Visit Sage Language Services on our Journal Author Gateway for further information.

    5. Research Data and Reporting Guidelines

    The journal is committed to facilitating openness, transparency, and reproducibility of research, and has the following research data sharing policy. 

    Subject to appropriate ethical and legal considerations, authors are encouraged to:

    • share your research data in a relevant public data repository
    • include a data availability statement linking to your data. If it is not possible to share your data, we encourage you to consider using the statement to explain why it cannot be shared.
    • cite this data in your research

    5.1 Reporting Methods

    Describe statistical methods with enough detail to enable a knowledgeable reader with access to the original data to judge its appropriateness for the study and to verify the reported results. When possible, quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals). Avoid relying solely on statistical hypothesis testing, such as P values, which fail to convey essential information about effect size and precision of estimates. References for the design of the study and statistical methods should be to standard works when possible (with pages stated). Define statistical terms, abbreviations, and most symbols. Specify the statistical software package(s) and versions used. Distinguish prespecified from exploratory analyses, including subgroup analyses.

    • Describe the type of study, e.g., randomized clinical trial phase III, pilot, case–control, meta-analysis etc.
    • Indicate the aim of the statistical analysis (primary objective, secondary objective, exploratory or ancillary analysis).
    • Describe the statistical methods in the order in which are used in the results.
    • Make it clear which statistical test was used for which variable.
    • State if any assumptions were checked and how.
    • Describe how missing data was handled (if data is missing).
    • Describe any planned sensitivity or subgroup analyses.
    • If relevant, include a sample-size calculation, with sufficient detail so it can be verified, and report the minimal clinically significant difference (if possible).
    • Report the alpha-level (one or two sided) and the statistical package.
    • Describe with enough detail to enable a knowledgeable reader with access to the original data to verify the reported results. For more details about reporting standards, please see the ICJME recommendations.

    5.2 Reporting Results

    • Present in the same order of importance as described in the methods.
    • Include effect sizes and their 95% confidence intervals with the appropriate degree of precision, in addition to P-values. Please read this editorial and accompanying paper on how to report confidence intervals.
    • Adjusted data for multiple testing.
    • Include both absolute and relative measures.
    • Provide enough detail that the results can be incorporated into other analyses; for example, in future meta-analytical studies if reporting a continuous outcome, provide mean (standard deviation), while for categorical outcomes when reporting relative summary statistics, please include the frequency of the outcome (numerator) over the total sample observed (denominator). In addition to these recommendations, all applicable general and study-specific SAMPL guidelines should be followed. 

    The relevant EQUATOR NETWORK reporting guidelines should be followed depending on the type of study.

    • CONSORT: Evidence-based, 25-item checklist containing the minimum recommendations for reporting Randomized Clinical Trials (RCTs).
    • STROBE: Cohort, case-control, and cross-sectional studies.
    • PRISMA: Reporting systematic reviews and meta-analyses.
    • CARE: Evidence-based, minimum recommendations for case reports. The CARE guidelines provide early signs of what may work for patients.
    • ARRIVE: For reporting animal research and peer-reviewers of animal research studies.
    • SQUIRE: For reports that descrie system level work to improve the quality, safety, and value of healthcare, and used methods to establish that observed outcomes were due to the intervention(s).

    Example:

    Randomized Controlled Trials

    Authors of randomized controlled trials must follow the guidelines presented in the CONSORT statement, and submit a completed CONSORT manuscript checklist with their manuscript. A copy of the "CONSORT Checklist for Authors Submitting Reports of Randomized Controlled Trials" may be downloaded from the JAAD Web site. Similar guidelines for authors of observational and epidemiologic studies are included in the STROBE statement and the related RECORD checklist, for observational comparative effectiveness studies in the GRACE principles, and for studies of diagnostic accuracy in the STARD statement.

    Other resources can be found at NLM’s Research Reporting Guidelines and Initiatives.

    6. Editorial Policies

    6.1 Peer Review Policy

    JPPA operates a conventional single-anonymized reviewing policy in which the reviewer’s name is always concealed from the submitting author.

    The editorial staff will review the manuscript and, if it meets JPPA’s editorial standards and submission criteria, will send it to at least two reviewers. Reviewers are experts in their fields who can provide an objective assessment of the manuscript. Reviewers will not be assigned to a paper if:

    • The reviewer is based at the same institution as any of the co-authors.
    • The reviewer is based on the funding body of the paper.
    • The author has recommended the reviewer.
    • The reviewer has provided a personal email address (e.g., Gmail/Yahoo/Hotmail) and an institutional email account cannot be found after performing a basic Google search (name, department, and institution).

    Reviewers will pay particular attention to scientific accuracy, adherence to reporting guidelines, relevance, novelty, importance, and appropriate style of the submission. Decisions on manuscripts will be made as rapidly as possible. 

    Some degree of manuscript revision should be expected and regarded as constructive. A request to submit a revised manuscript does not guarantee that it will be accepted; rather this means the submission will be reconsidered after additional peer review.

    The Editor or members of the Editorial Board may occasionally submit their own manuscripts for publication in the Journal. In these cases, the peer review process will be managed by alternative members of the Board and the submitting Editor/Board member will not be involved in the decision-making process.

    The Editors also require the reviewer to disclose any competing interests or conflicts of interest that might interfere with their objectivity (or to recuse oneself from acting as a reviewer). The Editors and members of the editorial staff have registered their competing interests with the National Psoriasis Foundation. The Editors and members of the editorial staff will ensure that all conflicts are appropriately resolved. Conflicts that cannot be appropriately resolved will result in rejection of the manuscript or review. Undisclosed conflicts may result in sanctions.

    JPPA is committed to delivering high quality, peer-review for your paper, and thus has partnered with Web of Science (previously Publons). Web of Science is a third-party service that seeks to track, verify, and give credit for peer review. Reviewers for JPPA can opt in to Web of Science to claim their reviews or have them automatically verified and added to their reviewer profile. Reviewers claiming credit for their review will be associated with the relevant journal, but the article name, reviewer’s decision and the content of the review is not published on the site. For more information visit the Web of Science website.

    6.2 Authorship

    6.2.1 Authorship Conditions

    Papers should only be submitted for consideration once consent is given by all contributing authors. JPPA adheres to the authorship guidelines outlined in the ICMJE Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals.

    In summary, each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. Acquisition of funding, collection of data, or general supervision of the research group alone does not constitute authorship, although all contributors who do not meet the criteria for authorship should be listed in the Acknowledgments section.

    Authors should meet all the following ICMJE recommendations:

    1. Made a substantial contribution to the concept and design, acquisition of data or analysis and interpretation of data; AND

    2. Drafted the article or revised it critically for important intellectual content; AND

    3. Final approval of the version to be published. AND

    4. Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

    6.2.2 Corresponding Author

    All authors should identify one corresponding author who accepts primary responsibility for the submission, peer-review, and publication process. The JPPA editorial staff will only communicate with the corresponding author, however, other authors can be designated to receive relevant emails.

    Upon acceptance of manuscript, the corresponding author must submit a License to Publish form. This contributor form will be emailed to the address on file. Additionally, the corresponding author’s complete address, telephone and fax numbers, and e-mail address must be provided on the title page.

    Please note that AI chatbots, for example ChatGPT, should not be listed as authors. For more information see the policy on Use of ChatGPT and generative AI tools.

    6.3 Acknowledgements

    All contributors who do not meet the criteria for authorship should be listed in an Acknowledgements section. Examples of those who might be acknowledged include a person who provided purely technical help, or a department chair who provided only general support.

    Any acknowledgements should appear first at the end of your article prior to your Declaration of Conflicting Interests (if applicable), any notes and your References.

    6.3.1 Third party submissions

    For individuals who have provided writing assistance and/or submit a manuscript on behalf of the author(s) but who do not qualify as authors, a statement must be included in the Acknowledgements section of the manuscript and in the accompanying cover letter. The statements must:

    • Disclose this type of editorial assistance – including the individual’s name, company, and level of input
    • Identify any entities that paid for this assistance
    • Confirm that the listed authors have authorized the submission of their manuscript via third party and approved any statements or declarations, e.g., conflicting interests, funding, etc.

    It is not necessary to disclose the use of language polishing services.

    Where appropriate, Sage reserves the right to deny consideration to manuscripts submitted by a third party rather than by the authors themselves.

    6.4 Funding

    The Journal requires all authors to acknowledge their funding in a consistent fashion under a separate heading. It should appear under the heading ‘Funding’ after any Acknowledgments and Declaration of conflicting interests, and before Notes and References. Please visit the Funding Acknowledgements page on the Sage Journal Author Gateway to confirm the format of the acknowledgment text in the event of funding, or state that: This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.

    6.5 Declaration of Conflicting Interests

    JPPA requires a declaration of conflicting interests from all authors enabling a statement to be carried within the paginated pages of all published articles. 

    The Journal requires all authors to acknowledge their institutional or corporate affiliations and funding sources. These include, but are not limited to, employment, royalties, consulting arrangements with a commercial entity, stock or other equity ownership, stock options, patent licensing arrangements, payments for conducting or publicizing a product or study, or consulting relationships with investment companies. In addition, authors are required to disclose similar associations with companies that make a competing product.

    Please ensure that a "Declaration of Conflicting Interests" statement is included at the end of your manuscript, after any acknowledgements and prior to the references. Please ensure that each author is represented in the statement. If no conflict exists, please state that "The Author(s) declare(s) that there are no conflicts of interest." It is acceptable to indicate authors by their initials.

    For guidance on conflict-of-interest statements, please see the ICMJE recommendations here.

     7. Submitting Your Manuscript

    JPPA is hosted on Sage Track, a web based online submission and peer review system powered by ScholarOne™ Manuscripts. Visit https://mc.manuscriptcentral.com/JPPA to login and submit your article online.

    IMPORTANT: Please check whether you already have an account in the system before trying to create a new one. If you reviewed or wrote for the journal in the past year, you will have had an account created. For further guidance on submitting your manuscript online please visit ScholarOne Online Help.

    7.1 ORCID

    As part of our commitment to ensuring an ethical, transparent, and fair peer review process, Sage is a supporting member of ORCID, the Open Researcher and Contributor ID. ORCID provides a unique and persistent digital identifier that distinguishes researchers from every other researcher, even those who share the same name, and, through integration in key research workflows such as manuscript and grant submission, supports automated linkages between researchers and their professional activities, ensuring that their work is recognized.

    The collection of ORCID IDs from corresponding authors is now part of the submission process of this journal. If you already have an ORCID ID, you will be asked to associate that to your submission during the online submission process. We also strongly encourage all co-authors to link their ORCID ID to their accounts in our online peer review platforms by following the below steps:

    Click the link when prompted, sign into your ORCID account and our systems are automatically updated. Your ORCID ID will become part of your accepted publication’s metadata, making your work attributable to you and only you. Your ORCID ID is published with your article so that fellow researchers reading your work can link to your ORCID profile and from there link to your other publications.

    If you do not already have an ORCID ID, please follow this link to create one or visit our ORCID homepage to learn more.

    8. On Acceptance and Publication

    8.1 Sage Production

    Your Sage Production Editor will keep you informed as to your article’s progress throughout the production process. Proofs will be made available to the corresponding author via our editing portal Sage Edit or by email, and corrections should be made directly or notified to us promptly. Authors are reminded to check their proofs carefully to confirm that all author information, including names, affiliations, sequence, and contact details are correct, and that Funding and Conflict of Interest statements, if any, are accurate.

    8.2 OnlineFirst Publication

    OnlineFirst allows final articles (completed and approved articles awaiting assignment to a future issue) to be published online prior to their inclusion in a journal issue, which significantly reduces the lead time between submission and publication. Visit the Sage Journals help page for more details, including how to cite OnlineFirst articles.

    Sage provides authors with online access to their final article.

    8.3 Promoting Your Article

    Publication is not the end of the process! You can help disseminate your paper and ensure it is as widely read and cited as possible. The Sage Author Gateway has numerous resources to help you promote your work. Visit the Promote Your Article page on the Gateway for tips and advice.

    For information and guidance on how to make your article more discoverable, visit our Gateway page on How to Help Readers Find Your Article Online.

    9. Further Information

    Any correspondence, queries, or additional requests for information on the manuscript submission process should be sent to the JPPA editorial office: jppa@psoriasis.org.

    9.1 Appealing the Publication Decision

    Editors have very broad discretion in determining whether an article is an appropriate fit for their journal. Many manuscripts are declined with a very general statement of the rejection decision. These decisions are not eligible for formal appeal unless the author believes the decision to reject the manuscript was based on an error in the review of the article, in which case the author may appeal the decision by providing the Editor with a detailed written description of the error they believe occurred.

    If an author believes the decision regarding their manuscript was affected by a publication ethics breach, the author may contact the publisher with a detailed written description of their concern, and information supporting the concern, at publication_ethics@sagepub.com.

    For further information including guidance on fair dealing for criticism and review, please see the Copyright and Permissions page on the Sage Author Gateway.
