Instructions for sending contributions to Public Opinion


Opinião Pública publishes scientific articles by Brazilian and international researchers on theory and methodology in public opinion, social and political behavior, political culture and democracy, media studies, elections, and political representation, articles which base their themes or hypotheses on theoretical frameworks and on empirical, quantitative, qualitative, or documentary research data in order to generate findings and support conclusions.

Opinião Pública is progressively aligning with open science procedures by adopting the CC-BY (Creative Commons Attribution) license, providing open access to data, analysis methods, and other research materials used in investigations (available on this site, at the end of the page referring to the article, section Public Opinion Journal), and allowing the submission of the author’s original version of a manuscript that has been previously posted on preprint servers: Scielo (, Social Science Research Network ( and ResearchGate (

Opinião Pública also accepts articles presented in conference proceedings. If approved, its publication is subject to the withdrawal of the Annals or Collection where it was previously published.

Articles shall be submitted (in .doc format) exclusively through the online submission system Scielo/ScholarOne: The articles cannot be submitted for publication or consideration in any other journal. The publications included in the Public Opinion Journal are submitted to a process of anonymous review by specialists (double-blind review). Articles from the preprint server go through the one-blind review evaluation process.

The journal Public Opinion publishes articles in Portuguese, Spanish, and English. In order to guarantee anonymity in the evaluation, the name(s) of the author(s) shall NOT appear in the body of the text, nor shall there be any other reference that enables identification.  If the article is approved for publication, the copyright must be assigned to Cesop/Unicamp, mentioning agreement with the publication, which must also include the name, full address, telephone, fax, e-mail, title and the institution to which author is linked. The author must also share databases, codes, methods and other materials used and resulting from the research presented in the published article.

The publication of a new article from an author whose work has been previously selected for publication in past issues must wait the period of one (1) year from the publication of the prior edition.

The abstracts must come in four versions: Portuguese, English, French, and Spanish, and must be a maximum of 200 words. The abstracts must contain the description of the analyzed object and the article objectives; type of research methodology or approach used; results; implications; and originality of the article. The article must be between 20 and 40 pages, including images, notes, and references. The page layout must be A4 standard with 1.5 cm left and right margins, Times New Roman 12-point font, and 1.5 line spacing. The title of the article cannot exceed the maximum of 20 words and must be presented in all four languages, in addition to five keywords that identify the content. Frames, maps, tables, etc. must be in their proper place in the body of the text. In the event an article is selected for publication, the author(s) shall deliver all content as separated files, as objects in Word, enabled for editing.

Citations must be done in the body of the text and composed as follows: (Last Name of the Author, date) or (Last Name of the Author, date, page). E.g.: (Souza, 1976; Assis, 2000) or (Souza, 1976, p. 64). Different titles by the same author published the same year shall be identified by a letter after the date. E.g.: (Almeida, 1989a), (Almeida, 1989b). In the event that two authors are cited for one publication or two publications are attributed to the same author, the citations must appear as follows: (Souza and Almeida, 1990; Sanches, 2000, 2005).

The bibliographical references used must be presented at the end of the article, listed alphabetically, according to the ABNT norms (NBR 6023), as in the following examples.

Dataset availability. The dataset the authors used in the article must be assigned to the journal and shall be available for access in the Cesop website. 

We ask that close attention be paid to the spelling of names and to the dates of publications cited in the text and in the bibliographical references in order to minimize any discrepancies.

The Public Opinion journal team will ultimately revise typographical errors, spelling, grammar, spelling of proper names, acronyms, publication dates in the citations, and bibliographical references; however, the more careful the contributors are with all of these aspects, the lesser the chances of errors in the article to be published.
