Using American Psychological Association (APA) Format
(Updated to 5th Edition)

Brought to you by the Purdue University Online Writing Lab.

If you are asked to use APA format for a paper, the book to consult is the Publication Manual of the American Psychological Association (5th edition), which the American Psychlogical Association has recently updated. Citing electronic sources was a major part of this update as these types of sources are increasingly common in research within the social sciences. Below, you will find some examples of these updated citation styles. If you want to order an APA manual or view the latest updates about electronic sources in more detail, visit the new APA style web site at http://www.apastyle.org or consult our additional resources section for lots of links to helpful information. For a guide to writing papers in psychology, check out George Mason University's Psychology Writing Guide (at http://www.gmu.edu/departments/psychology/writing/index.htm) or the University of Washington's Psychology Writing Center (at http://depts.washington.edu/psywc/).

We have created an APA style workshop (http://owl.english.purdue.edu/workshops/hypertext/apa/index.html) that offers a wealth of information about writing and formatting papers in APA style. This handout covers the following basic issues:

  • General Format
  • Referring to the Works of Others in Your Text
  • Your Reference List
  • Examples
  • Notes
  • Additional Resources

We also have a PowerPoint presentation available at http://owl.english.purdue.edu/workshops/pp/index.html that covers APA style basics.

General Format

General format for manuscripts written in APA style is covered in the first chapter of the Publication Manual, starting on page ten. What follows are some general guidelines for formatting. For more information about how to format a manuscript, see the many links in our additional resources section.

Your essay should be typed, double-spaced on standard-sized paper (8.5 X 11 inches) with margins of 1 inch on all sides. Your final essay should include, in the order indicated below, as many of the following sections as are applicable, each of which should begin on a separate page:

  • title page, which includes a running head for publication, title, and byline and affiliation
  • abstract
  • text
  • references
  • appendixes
  • author note
  • footnotes/endnotes
  • tables
  • figure captions
  • figures

The pages of your manuscript should be numbered consecutively, beginning with the title page, as part of the manuscript header in the upper right corner of each page. Your references should begin on a separate page from the text of the essay under the label References (with no quotation marks, underlining, etc.), centered at the top of the page. Appendices and notes should be formatted similarly.

Here is a sample title page in APA format. Note how it includes the running head and page number in the upper right hand corner, defines the running head that will title all manuscript pages, and centers the title in the middle of the page. Always remember to consult your instructor if you are writing a paper for a class; s/he may have different guidelines for how a title page should appear.

For more about formatting an APA style paper, consult the publication manual, visit APA Style Essentials (at http://www.vanguard.edu/faculty/ddegelman/index.cfm?doc_id=796), or view a Sample APA Report (at http://www.thewritesource.com/APA/APARESEARCH.HTM) or a APA Simulated Journal Article (at http://www-distance.syr.edu/apa5th.html). Annotated bibliography writers might want to visit APA Format for Annotated Bibliographies (at http://www.lesley.edu/library/guides/citation/apa_annotated.html).

Additional formatting resources, including Microsoft Word templates, are available in our additional resources section.


Handling Quotations In Your Text

Reference citations in text are covered on pages 207-214 of the Publication Manual. For more about in-text references in general, see the University of Wisconsin-Madison Writing Center's page on citations (at http://www.wisc.edu/writetest/Handbook/DocAPACitations.html) or visit the links in our additional resources section for more information. What follows are some general guidelines for referring to the works of others in your text.

When using APA format, follow the author-date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, and a complete reference should appear in the reference list at the end of the paper.

If you are referring to an idea from another work but NOT directly quoting the material, or making reference to an entire book, article or other work, you only have to make reference to the author and year of publication in your in-text reference.

If you are paraphrasing an idea from another work, you only have to make reference to the author and year of publication in your in-text reference, but APA guidelines encourage you to also provide the page number (although it is not required.)

If you are directly quoting from a work, you will need to include the author, year of publication, and the page number for the reference. See our sections on quotations for more information about this.

Examples for referring to another idea or study:

Jones (1998) compared student performance ...

In a recent study of student performance (Jones, 1998), ...

In 1998, Jones compared student performance ...

If there is no author to cite, such as when you are citing a web page that lists no author, use an abbreviated version of the title of the page in quotation marks to substitute for the name of the author.

A similar study was done of students learning to format research papers ("Using APA," 2001).

If you are citing a work that has no author and no date, use the first few words from the title, then the abbreviation n.d. (for "no date"). For more information about referring to electronic sources or sources without authors and/or dates in text, see Citations in Text of Electronic Material (at http://www.apastyle.org/electext.html) or Frequently Asked Questions about APA Style (http://www.apastyle.org/faqs.html) from the APA web site, or our additional resources section.

In another study of students and research decisions, it was discovered that students succeeded with tutoring ("Tutoring and APA," n.d.).

Personal communications, such as e-mail messages to you, or private interviews that you conducted with another person, should be referred to in your in-text citations but NOT in your reference list. (For more information, see page 214 of the Publication Manual.) To cite a personal communication, provide initials and last name of the communicator, the words personal communication, plus an exact date in the body of your paper.

For example:

A. P. Smith also claimed that many of her students had difficulties with APA style (personal communication, November 3, 2002).

Formatting Citations in Your Text

Here are some basic rules for formatting citations in the body of your paper. For more information about these rules, see pages 94-99 and 207-209 of the Publication Manual.

  • Always capitalize proper nouns, including author names.
  • If you refer to the title of a source within your paper, capitalize all words that are four letters long or greater within the title of a source.
  • When capitalizing titles, capitalize both words in a hypenated compound word.
  • After a colon or dash in a title, capitalize the first word.
  • Italicize the titles of longer works such as books, edited collections, movies, documentaries, or albums.
  • Put quotation marks around the titles of shorter works such as journal articles, articles from edited collections, television shows, and song titles.
  • If a work has two authors, cite both names every time the reference appears in your text. Join the authors' names with the word and.
  • If a work has three, four, or five authors, cite all of the authors the first time you refer to the work in your text. The next time you refer to the work, shorten the citation to the last name of the first author plus the words et al. Join the authors' names with the word and if you are referring to them in the text; join the authors' names with an ampersand (&) if you are referring to them in a paranthetical citation.
  • If a work has six authors (or more), cite only the last name of the first author plus the words et al.

Short Quotations

Formatting quotations is covered on pages 117-121 in the Publication Manual.

To indicate quotations of fewer than 40 words in your text, enclose the quotation within double quotation marks. Provide the author, year, and specific page citation in the text, and include a complete reference in the reference list. Punctuation marks, such as periods, commas, and semicolons, should appear after the parenthetical citation. Question marks and exclamation points should appear within the quotation marks if they are a part of the quotation but after the parenthetical citation if they are a part of your text.

Examples:

She stated, "Students often had difficulty using APA style," (Jones, 1998, p. 199), but she did not offer an explanation as to why.

According to Jones (1998), "Students often had dificulty using APA style, especially when it was their first time" (p. 199).

Jones (1998) found "students often had difficulty using APA style" (p. 199); what implications does this have for teachers?

If you are citing a work that has no author, no date, and no page numbers, use the first few words from the title, then the abbreviation n.d. (for "no date"), and then use paragraph numbers (if available) or simply leave out any reference to pages.

Example:

In another study of students and research decisions, it was discovered that students succeeded with tutoring ("Tutoring and APA," n.d.).

Long Quotations (block quotes)

Formatting long quotations is covered on pages 117-118 and 292-293 in the Publication Manual.

Place quotations longer than 40 words in a free-standing block of typewritten lines, and omit quotation marks. Start the quotation on a new line, indented five spaces from the left margin. Type the entire quotation on the new margin, and indent the first line of any subsequent paragraph within the quotation five spaces from the new margin. Maintain double-spacing throughout. The parenthetical citation should come after closing punctuation mark.

Example:

Jones's 1993 study found the following:

Students often had difficulty using APA style,especially when it was their first time citing sources. This difficulty could be attributed to the fact that many students failed to purchase a style manual or to ask their teacher for help. (p. 199)

Choosing double or single quotation marks

If you are using a quotation that uses quotation marks as a short quotation, use single quotation marks to set off the material that was originally enclosed in quotation marks. If you are using a quotation that uses quotation marks in a block quote, use double quotation marks to set off the material that was originally in quotation marks.

For more about in-text references in general, see the University of Wisconsin-Madison Writing Center's page on citations (at http://www.wisc.edu/writetest/Handbook/DocAPACitations.html) or visit the links in our additional resources section for more information.


Your Reference List

Formatting your reference list is covered in chapter four of the Publication Manual, which starts on page 215. Further information about citing sources and formatting your reference list can be found in our additional resources section. What follows are some general guidelines for formatting your reference list.

Your reference list should appear at the end of your paper. It provides the information necessary for a reader to locate and retrieve any source you cite in the body of the paper. Each source you cite in the paper must appear in your reference list; likewise, each entry in the reference list must be cited in your text.

Your references should begin on a separate page from the text of the essay under the label References (with no quotation marks, underlining, etc.), centered at the top of the page. It should be double-spaced just like the rest of your essay. If you would like to see a sample reference list, these links to Sample APA Report (at http://www.thewritesource.com/APA/APARESEARCH.HTM)and a APA Simulated Journal Article (at http://www-distance.syr.edu/apa5th.html) both provide sample reference lists that you can view.

Basic Rules

  • Authors' names are inverted (last name first); give the last name and initials for all authors of a particular work.
  • Reference list entries should be alphabetized by the last names of the first author of each work.

  • If you have more than one article by the same author(s), single-author references or multiple-author references with the exact same authors in the exact same order are listed in order by the year of publication, starting with the earliest.

    For example:

    Berndt, T. J. (1996). Exploring the effects of friendship quality on social development. In W. M. Bukowski, A. F. Newcomb, & W. W. Hartup, (Eds.), The company they keep: Friendship in childhood and adolescence.  (pp. 346-365). Cambridge, UK: Cambridge University Press.

    Berndt, T. J. (2002). Friendship quality and social development. Current Directions in Psychological Science, 11, 7-10.

    Wegener, D. T., & Petty, R. E. (1994). Mood management across affective states: The hedonic contingency hypothesis. Journal of Personality & Social Psychology, 66, 1034-1048.

    Wegener, D. T., & Petty, R. E. (1995). Flexible correction processes in social judgment: The role of naive theories in corrections for perceived bias. Journal of Personality & Social Psychology, 68, 36-51.


  • When an author appears both as a sole author and, in another citation, as the first author of a group, list the one-author entries first.

    For example:

    Berndt, T. J. (1999). Friends' influence on students' adjustment to school. Educational Psychologist, 34, 15-28.

    Berndt, T. J., & Keefe, K. (1995). Friends' influence on adolescents' adjustment to school. Child Development, 66, 1312-1329.


  • References that have the same first author and different second and/or third authors are arranged alphabetically by the last name of the second author, or the last name of the third if the first and second authors are the same.
    For example:

    Wegener, D. T., Kerr, N. L., Fleming, M. A., & Petty, R. E. (2000). Flexible corrections of juror judgments: Implications for jury instructions. Psychology, Public Policy, & Law, 6, 629-654.

    Wegener, D. T., Petty, R. E., & Klein, D. J. (1994). Effects of mood on high elaboration attitude change: The mediating role of likelihood judgments. European Journal of Social Psychology, 24, 25-43.


  • If you are using more than one reference by the same author (or the same group of authors listed in the same order) published in the same year, organize them in the reference list alphabetically by the title of the article or chapter. Then assign letter suffixes to the year.

    For example:

    Berndt, T. J. (1981a). Age changes and changes over time in prosocial intentions and behavior between friends. Developmental Psychology, 17, 408-416.

    Berndt, T. J. (1981b). Effects of friendship on prosocial intentions and behavior. Child Development, 52, 636-643.


    When referring to these publications in your paper, use the letter suffixes with the year so that the reader knows which reference you are referring to. For example: "Several studies (Berndt, 1981a, 1981b) have shown that..."

  • Use "&" instead of "and" when listing multiple authors of a single work.

  • If no author is given for a particular source, begin with and alphabetize by using the title of the work, which will be listed in place of the author, and use a shortened version of the title for parenthetical citations.

  • Personal communications, such as e-mail messages to you, or private interviews that you conducted with another person, should not be cited in your reference list because they are not retrievable sources for anyone else. You should make reference to these sources in your in-text citations. (For more information, see page 214 of the Publication Manual.)

  • All lines after the first line of each entry in your reference list should be indented one-half inch from the left margin. This is called hanging indentation.

  • When referring to any work that is NOT a journal, such as a book, article, or Web page, capitalize only the first letter of the first word of a title and subtitle, the first word after a colon or a dash in the title, and proper nouns. Do not capitalize the first letter of the second word in a hyphenated compound word.
  • Capitalize all major words in journal titles.
  • Italicize titles of longer works such as books and journals.
  • Do not italicize, underline, or put quotes around the titles of shorter works such as journal articles or essays in edited collections.

Basic Forms for Sources in Print

Our additional resources section also has some links to examples and resources.


A Note on Notes

Because long explanatory notes can be distracting to readers, APA style guidelines recommend the use of endnotes/footnotes. In the text, place a superscript numeral immediately after the text about which you would like to include more information (e.g., Scientists examined the fossilized remains of the wooly-wooly yak.1) Number the notes consecutively in the order they appear in your paper. At the end of the paper, create a separate page labeled Notes (with the title centered at the top of the page). Below are examples of two kinds of notes.

Evaluative bibliographic comments

1 See Blackmur (1995), especially chapters three and four, for an insightful analysis of this extraordinary animal.

2 On the problems related to yaks, see Wollens (1989, pp. 120-135); for a contrasting view, see Pyle (1992).

Explanatory or additional information considered too digressive for the main text

3 In a recent interview, she (Weller, 1998) reiterated this point even more strongly: "I am an artist, not a yak!" (p. 124).


Additional Resources

It's always best to consult the Publication Manual first for any APA question. If you are using APA style for a class assignment, it's a good idea to consult your professor, advisor, TA, or other campus resources for help with using APA style -- they're the ones who can tell you how the style should apply in your particular case. For extraordinary questions that aren't covered clearly in the style manual or haven't been answered by your teacher or advisor, contact the Writing Lab for help at (765) 494-3723 or email owl@owl.english.purdue.edu.

Here are some other resources for using APA style and writing research papers that might also help answer your questions.
