Policy Concerning Duplicate and Redundant Publications
Duplicate or redundant publication is a publication that overlaps substantially with one already published, in press, or in an electronic media submission. (International Committee of Medical Editors. http://www.icmje.org/publishing4overlap.html)
Duplicate or redundant submission is the same manuscript (or the same data) that is submitted to different journals at the same time. International copyright laws, ethical conduct, and cost effective use of resources require that readers can be assured that what they are reading is original. (International Council of Medical Editors. http://www.icmje.org/publishing4overlap.html)
Manuscripts that are submitted to JPP should not have been published or currently submitted elsewhere. Duplicate publication is a violation of the APA code of ethics (APA Publication Manual, 2010) and will be grounds for prompt rejection of the submitted manuscript. If the editor was not aware of the violation and the article has been published, a notice of duplicate submission and the ethical violation will be published in JPP and reported to APA.
Policy Concerning Reviews of Multiple Manuscripts That Originate from the Same Study
(See editorial for detail on policy: Drotar, D. (2010). Editorial: Guidance for submission and review of multiple publications derived from the same study. Journal of Pediatric Psychology, 35, 225.230)
There are good scientific reasons to publish multiple manuscripts from a single study (e.g. differences in questions addressed, distinct purposes, new scientific knowledge, etc.). However, multiple manuscripts from the same study can also result in piecemeal publication. A piecemeal publication is defined as the unnecessary submission of findings from the same study piece by piece as opposed to a more integrative single (or fewer) manuscript(s) (APA Publication Manual, 2010). Piecemeal publications overlap significantly in focus, content, or data, do not reflect a novel scientific contribution, and may limit scientific progress. Moreover, they can raise confusion in readers if they appear to be independent publications and lead to erroneous conclusions in meta-analyses. For these reasons, authors should avoid piecemeal publication. Manuscripts from the same study should be submitted only if they are important new scientific contributions compared with previous publications and manuscripts under review from the same study.
Recommendations for Authors Concerning Multiple Publications From the Same Study
Authors can facilitate effective editorial review of multiple manuscripts that originate from the same study by doing the following in a cover letter and relevant text of the manuscript:
1) Authors should in a cover letter and in the method section describe the larger study, and provide all relevant references related to the larger study even if these data are not yet published.
2) Authors should clarify the relationship between the larger study and data described in their manuscript: especially the research questions that have been examined in previous research versus those that are addressed in the submitted manuscript and the extent of overlap in methods, data, variables etc. in the various studies.
3) In a cover letter and in the body of the manuscript, authors should indicate a clear rationale for and state the new scientific contribution of their manuscript relative to any previously published research that was derived from the same study or data set.
4) Relevant submitted manuscripts and/or publications from the study should be included with the submission current under review. This will facilitate editorial review. This material should be uploaded with the original submission of the manuscript in a file with the designation name “Previously published ms (not for review or publication)." If necessary, multiple manuscripts/publications can be uploaded.
5) Suitable procedures for blinding should be used for those references that are cited in the text, e.g. when an authors name is mentioned in a study that clearly links back to the larger project from which the manuscript’s data are drawn. Please substitute the names with letters, e.g. XXX, in the text citations (see instructions for blinding on the JPP website). Names will be inserted upon final acceptance of the manuscript.
6) Authors should include a footnote on the title page of the manuscript that indicates the methods of this study are based on a study first reported in (provide reference).
Please note that failure to disclose complete information concerning multiple publications from the same study that relate to a submitted manuscript could be grounds for rejection of the manuscript.
INSTRUCTIONS TO MANAGING EDITORS CONCERNING MULTIPLE PUBLICATIONS FROM THE SAME STUDY
Editors will review the cover letter from authors regarding the description of the parent study, current submission, relevant publications, and previous submissions as relevant. Before assigning the manuscript to reviewers, editors should make an initial determination about whether the submission has the potential to make a new independent scientific contribution to research in pediatric psychology relative to what has already been published or submitted from the study. If the answer is yes then the manuscript will be sent out to reviewers. If the answer is no, then the manuscript will be rejected without additional review with a letter of explanation to the author that describes the rationale for the decision. This decision will be blinding. However, authors may submit other manuscripts from the same study.
INSTRUCTIONS TO REVIEWERS
Reviewers are charged with making a determination about whether the manuscript makes a new, significant, independent contribution to research in pediatric psychology based on the authors stated rationale. It is not uncommon that reviewers have knowledge of duplicate submissions or unacknowledged submissions or piece publications from a larger study that the managing editor of a manuscript does not know about. Reviewers who identify such submissions and publications should let the managing editor know immediately.
