In exceptional cases the word limit can be exceeded, but in principle this should be avoided. Supplementary material, like large tables, data sets, protocols, videos, questionnaires, non-English versions of the article can be uploaded as supplementary material and will thus also be available online.
Checklists and guidelines Please make use of checklists that are available for a number of study designs, including randomized controlled trials (CONSORT). Here you will also find quidelines for meta-analyses (MOOSE) and on studies of diagnostic accuracy (STARD). Further useful links are those to systematic reviews Cochrane Reviewers' Handbook and PRISMA, and to observational studies (STROBE).
Cover Letter In the cover letter, the corresponding author should reveal whether the submitted article – or very similar work - has been previously published or orally presented, or is under consideration elsewhere. If the manuscript forms part of a book currently in press, the authors should specify details of the publisher and expected date of publication. The author should also indicate if he/she is a member of ESTSS and and if so, give the membership details.
The authors are also encouraged to list at least 2 potential reviewers with full name, institution, email address and area of expertise. Please note: the suggested reviewers should not be from the authors’ own institute, nor a co-author of any published paper/papers of the present author/authors. The Editors reserve the right of final selection.
Acknowledgements All contributors who do not meet the criteria for authorship should be listed in an acknowledgments section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chairperson who provided only general support. Financial and material support should also be acknowledged.
Conflict of interest and funding Authors are responsible for disclosing financial support from the industry or other conflicts of interest that might bias the interpretation of results.
Ethics and consent When reporting experiments on patients or animals, please indicate whether the procedures followed were approved by your local ethics committee and/or in accordance with the Helsinki Declaration of 1975, as revised in 2008 (http://www.wma.net/en/30publications/10policies/b3/17c.pdf).
Language All articles should be written in English - British or American as long as consistency is observed. SI units should be used.
TranslationsESTSS acknowledges the very important role played by scientific literature published in countries where English is not the first language, and seeks to increase visibility of literature that would otherwise be accessible only within the borders of those countries. For this reason, the Journal encourages authors to submit their paper in the original language as well, for co-publication with the official English-language version.
The English abstract will be translated into German (Rita Rosner), French (Louis Jehel and Yann Quidé), Italian (Laura Porry), Spanish (Dani Mosca and Dolores Mosquera), Russian (Marina Scherbak), Turkish (Gözde Koçak), and Polish (Maja Lis-Turlejska). If anyone would like to translate the abstract into another language please contact the Editor, and we would be very happy to display this translation as well.
The translations can be found by clicking on the link below the English abstract or by clicking on Supplementary files (highlighted) in the column to the right (Reading Tools).

MANUSCRIPT LAYOUT - research articles
(Click here to download the guidelines in PDF format)
Wherever possible, the paper should follow the traditional layout: Title, Biographical details, Abstract, Keywords, Background, Objective, Method, Results, Discussion, Conclusions, References, Tables, Figures.
Title The title should be informative and accurate and at the same time trigger the interest of the reader. A short running head will be derived from the title to appear on each page of the paper.
Title page Organize the title page in the following way: 1) title of manuscript, 2) name of author(s), 3) name of department(s) and institution(s), and 4) name and full postal and email address of the corresponding author who also acts as 'Guarantor' for all parts of the paper. Please observe that the journal adheres to a 'double blind' review process and thus, the identity of the authors should remain unknown until the paper is accepted; the submitted paper should not include author name, affiliation and corresponding author address. Please see Ensuring a Blind Review
Abstract Articles must include a structured abstract of 200-300 words providing sufficient information for a reader to be able to decide whether or not to proceed to the full text of the article. The abstract should be structured in the following way (incl. these headings): Background, Objective, Method, Results, Conclusions.
Keywords After the abstract, please give 5-10 key words for readers looking for material by key word searching on Internet. Avoid using the same words as in the title.
Figures Upon acceptance please supply figures/graphics/images in at least 300 dpi. For further information please see Guidelines.
If the figures/graphics/images have been taken from sources not copyrighted by the author, it is the author’s sole responsibility to secure the rights from the copyright holder to reproduce those figures/graphs/images for both worldwide print and web publication. All reproduction costs charged by the copyright holder must be borne by the author.
When figures/graphics/images are reproduced, a parenthesis should be added to the figure legend thus: (Reproduced with permission from xxx.)
Section headings Please do not number section headings. Use a maximum of three levels of headings made clear by orthographic indicators, i.e. capitals, italics, bold etc.
Quotations Please use double quotation marks. Quotations longer than 40 words should appear in a separate paragraph, indented by tapping a ca 1cm right margin, without quotation marks.
Citation and reference system The European Journal of Psychotraumatology applies to the APA system. Check for full details here or here (oral presentation).
APA style uses the author-date citation system allowing the readers to find the sources cited in the text in the reference list, where each source is listed alphabetically.
Style in the text:
To insert a citation in text, include the author’s surname and year of publication. For a direct quotation, include the page number of specific location of the phrase or sentences in the original work.
EXAMPLES:
- Kessler (2003) found that among epidemiological samples ...
- Early onset results in a more persistent and severe course (Kessler, 2003)
- In 2003, Kessler’s study of epidemiological samples showed that …
- Training materials are available (Department of Veterans Affairs, 2001, 2003)
- Several studies (Derryberry & Reed, 2005a, 2005b, in press-a, Rothbart, 2003a, 2003b) show...
Style in the reference list:
All citations should be listed in the reference list, with the exception of personal communications and classical works.
Put references in order by the author’s surname or first author’s surname if there is more than one author.
Use the hanging indent paragraph style. Double-space the entire reference list.
