1. Psicothema publishes works of an empirical nature, in English, that are carried out with methodological rigour and which make a contribution to the advance of any field of scientific psychology. Exceptionally, the Editorial Board will accept the publication of a work in Spanish if the content justifies this decision. It also accepts works of a theoretical nature (previously proposed or requested by the Editorial Committee), giving preference to those that deal with critical research issues and discuss controversial approaches. Furthermore, interdisciplinarity is one of the journal's prime concerns.
2. Articles must be unpublished. Psicothema shall not accept any work that has been totally or partially published elsewhere, nor those that are in the process of publication or have been presented for review by another journal. It is assumed that all those who appear as authors and those named as responsible for correspondence have given their consent.
3. Articles must be in Word and have a maximum length of 6,000 words (including title, abstract, references, figures, tables, appendices and illustrations). Manuscripts must be double-spaced, with 3 cm margins and page numbers at top right. On the first page, for purposes of anonymity, only the title and the total number of words will appear, and not the authors' names. Authors must try to avoid including in the text any clues to their identity. The second page must include an abstract, in English and Spanish, of not more than 200 words. The abstract should be structured into the following sections: Background, Method, Results and Conclusions.
Figures and tables must be included at the end of the manuscript, one per page. They should be composed by the authors in the form they wish them to appear, and should be numbered appropriately. Their position in the text should be indicated. Their base must measure 7 or 14 cm, and the letters and symbols that appear in them must be clear. Blank spaces should be avoided, making as economical use as possible of the space available. The criterion for calculating the approximate space occupied by tables and figures is as follows: two figures of 14 x 20 cm are equivalent to a printed page of Psicothema and three pages of double-spaced text. In the case of photographs, they must have a base of 7 or 14 cm and a maximum height of 20 cm.
All manuscripts will be reviewed anonymously. Authors should suggest three possible reviewers they consider suitable for reviewing their work, clearly indicating their postal address and e-mail. Likewise, authors may indicate the names of people whom, for whatever reason, they do not wish to be involved in the review process.
4. Manuscripts should adhere to the publication norms of the APA (Publication Manual of the American Psychological Association, 5th or 6th edition). Below we summarize the most important of these requirements and mention some further ones.
Bibliographical references within the text should give author's surname and year of publication (in brackets and separated by a comma). If the author's name forms part of the narrative it should be followed in brackets by the year of publication. If there are only two authors both should be cited in all cases. In cases of more than two but less than six authors, all should be cited the first time, and on all subsequent occasions only the name of the first author followed by "et al." and the year. The exception to this is when there is another case of the same surname and the same year, in which case the complete list of authors should be included. For more than six authors the "et al." form should be used throughout, in case of confusion adding subsequent authors until the work is clearly identified. Where different works are cited within the same brackets, they should be ordered alphabetically by first author. For works by the same author(s) and from the same year, the letters a, b, c, etc., should be added to the year, which should always be included.
The list of references at the end of the article shall be ordered alphabetically and according to the following norms:
a) Books: Author (surname, comma, initials of first name(s) and full stop; in cases of various authors, these are to be separated by a comma and before the last one with an "&"); year (in brackets) and full stop; full title in italics and full stop; city of publication and colon followed by publisher. Example:
Lezak, M., Howieson, D. B., & Loring, D. W. (2004). Neuropsychological Assessment (4th ed.). New York: Oxford University Press.
b) For chapters from books with various authors, articles from reports of conferences or similar: Author(s) of the chapter or article used; year; title of the chapter or article and full stop. These should be followed by "In", the director(s), editor(s) or compiler(s) (initials of the name; surname), and in brackets, Ed., adding an "s" in case of plurals; title of the book in italics, and pages covered by the chapter or article in brackets; city and publisher. Example:
de Wit, H., & Mitchell, S. H. (2009). Drug Effects on Delay Discounting. In G. J. Madden & W. K. Bickel (Eds.), Impulsivity: The Behavioral and Neurological Science of Discounting (pp. 213-241). Washington, DC: American Psychological Association.
c) For journals: Author(s); year; title of the article; full name of the journal in italics; vol. in italics; issue number in brackets without separation from volume number, and pages covered by the article. Example:
Byrne, B. M. (2008). Testing for multigroup equivalence of a measuring instrument: A walk through the process. Psicothema, 20, 872-882.
d) For web references: Authors are required to archive any web references before citing them using WebCite ® technology. This is an entirely free service that ensures that cited webmaterial will remain available to readers in the future.
If the original version of a non-English book is used, give the original title and, in brackets, the English translation. For all other norms please consult the APA manual (APA. 2001, 2010).
5. If an article is accepted for publication the rights of printing and reproduction in any form belong to Psicothema, which will not reject reasonable request from the author(s) to obtain permission for the reproduction of their contributions. It is understood that the opinions expressed in the articles are the exclusive responsibility of the authors, and do not compromise the opinion and scientific policy of the journal. Likewise, the activities described in work published in Psicothema shall be in accordance with generally accepted criteria of ethics, in relation to experimentation with both humans and animals, and with all aspects of professional deontology. It is the author's responsibility to be able to provide to interested readers copies of raw data, procedural manuals, scores, and relevant experimental material in general.
6. Articles shall be submitted via the journal's website: www.psicothema.com (authors' section). Receipt will be acknowledged immediately, and at the earliest possible opportunity the author will be informed of a decision about acceptance. Part of the costs of composition and publishing of the work will be the responsibility of the authors. The author will receive the offprint in PDF format and a hardcopy of the number in which the article will be published.
