American Psychological Association (APA) style is an academic format specified in The Publication Manual of the American Psychological Association, a style guide that offers academic authors guidance on various subjects for the submission of papers to the publications of APA. The APA states that the guidelines were developed to assist reading comprehension in the social and behavioral sciences, for clarity of communication, and for "word choice that best reduces bias in language". The Publication Manual of the American Psychological Association contains guidelines on many aspects of academic writing as it is regarded as appropriate by the APA. Among the topics covered are information on the structure of research papers of various kinds, spelling rules, an author-date reference style, construction of tables and graphs, plagiarism, formatting of papers, and much more.
APA style is widely used, either entirely or with modifications, by hundreds of other scientific journals (including medical and other public health journals), in many textbooks, and in academia (for papers written in classes). Along with AMA style and CSE style, it is one of the major style regimes for such work. Many publications have small local style guides that cascade over AMA, APA, or CSE style in a way analogous to how inline styles in HTML cascade over CSS styles (for example, "follow APA style unless otherwise specified herein" or "for issues not addressed herein, follow APA style").
The Publication Manual was established in 1929 as a seven-page document with a set of procedures to increase the ease of reading comprehension (APA, 2009a, p. xiii). Created under the sponsorship of the United States National Research Council, its originators included psychologists, anthropologists, and publishing professionals.
In 1952, the booklet was expanded and published as a 55-page supplement in Psychological Bulletin with revisions made in 1957 and 1967 (APA, 1952, 1957, 1967). The first edition covered word choice, grammar, punctuation, formatting, journal publication policies, and "wrapping and shipping" (APA, Council of Editors, 1952, p. 442).
In response to the growing complexities of scientific reporting, subsequent editions were released in 1974, 1983, 1994, and 2001. Primarily known for the simplicity of its reference citation style, the Publication Manual also established standards for language use that had far-reaching effects. Particularly influential were the "Guidelines for Nonsexist Language in APA Journals," first published as a modification to the 1974 edition, which provided practical alternatives to sexist language then in common usage. The guidelines for reducing bias in language have been updated over the years and presently provide practical guidance for writing about race, ethnicity, age, gender, sexual orientation, and disability status (APA, 2009, pp. 70–77; see also APA, 2009b).
Sixth edition of the Publication Manual
The sixth edition of the Publication Manual of the American Psychological Association was released in July 2009 after four years of development. The Publication Manual Revision Task Force of the American Psychological Association established parameters for the revision based on published criticism, user comments, commissioned reviews, and input from psychologists, nurses, librarians, business leaders, publishing professionals, and APA governance groups (APA, 2007a, 2007b). To accomplish these revisions, the Task Force appointed working groups of four to nine members in seven areas: Bias-Free Language, Ethics, Graphics, Journal Article Reporting Standards, References, Statistics, and Writing Style (APA, 2009, pp. xvii–xviii).
The APA explained the issuing of a new edition only eight years after the fifth edition by pointing to the increased use of online source or online access to academic journals (6th edition, p. xv). The sixth edition is accompanied by a web presence.
Errors in the first printing of the sixth edition
Despite multiple reviews of the manuscript at the copy-editing and proof-reading stages by senior editors, staff realized, shortly after the manual had gone to press, that the sample papers contained multiple errors. Among the detected errors were:
- In 188 style guidelines, two errors were made, and one of these was a punctuation error.
- In almost 1,000 examples provided to illustrate those rules, 36 errors were made (roughly half of these occurred in the sample papers, which were subsequently corrected and posted online). Another 10 occurred in the 374 examples that were provided in the reference chapter.
- Five clarifications to text were made. These were not errors, but rather clarified and expanded text, for example, adding a second example for both a blog post and a blog comment.
- Three pages of nonsignificant typographical errors were corrected. These included such things as changing an em dash to an en dash, changing a minus sign to a hyphen, and correcting for added space that was automatically added when a sample form was reproduced.
In the interest of transparency (and following the same procedure that was followed for the fifth edition), staff posted all of the corrections online in a single document on October 1, 2009, and shortly thereafter alerted users to the existence of the corrections in an APA blog entry. On the same day the corrections were posted, an individual posting to the Educational and Behavioral Sciences Section mailing-list (EBBSS-L) of the American Library Association alerted readers to what she described as the "many" errors in the first printing, and speculated that "some but not all" would be corrected in a second printing. On October 5, 2009, APA staff responded to the note, clarifying that errors were found in the sample papers, that the papers had been corrected and posted online, that the substantive guidance in the manual was correct and accurate as printed, and that a full list of corrections could be found at the APA Style website. Nevertheless, APA refused initially to exchange submitted erroneous books of the first with corrected versions of the second printing.
On October 13, 2009, the article "Correcting a Style Guide" was published in the online newspaper Inside Higher Ed that included interviews with several individuals who defined the errors as "egregious" (Epstein, 2009). The article, along with rumors spread on various mailing-lists, resulted in exaggerated accounts of both the magnitude and the extent of the errors, with some reports on Amazon.com claiming more than 80 pages of errors had occurred. APA responded to the increasing confusion by issuing an apology, and implementing a return/replacement program for purchasers who wished to exchange their first-printing copies for second-printing copies of the Publication Manual. The first-edition copies returned to APA were destroyed. The second and all subsequent printings of the Publication Manual have been fully corrected.
