PSYC 310R: Research Methods in Social Psychology: APA 7th

APA

About APA 7th edition

Recently updated by the American Psychological Association, the 7th edition of the APA style has some new best practices. It is still most widely used for research papers in psychology, social sciences, and many STEM courses.

Citing a source in this style consists of two parts:

  1. An in-text citation
  2. A reference list entry

See How to Format In-Text Citations, How to Format the Reference List, and the Examples in the left navigation for details.

How to Format In-Text Citations (Section 8 of the APA Manual)

For more detailed information see Publication Manual sections 8.10-8.22.

An in-text citation provides your reader with two pieces of information:

  1. The last name(s) of the author(s) from the corresponding reference list entry
  2. The date of the cited information

Standard Formatting of the In-Text Citation

Table summarizing Basic In-Text Citations in APA 7th Edition Style
Author Type Parenthetical Citation Narrative Citation
One author (Myrick, 2015) Myrick (2015)
Two authors (Hinsch & Sheldon, 2013) Hinsch and Sheldon (2013)
Three or more authors (Nabi et al., 2006) Nabi et al. (2006)

Group author with abbreviation - First citation

Group author with abbreviation - Subsequent citations

(National Institute of Mental Health [NIMH], 2015)

(NIMH, 2015)

National Institute of Mental Health (NIMH, 2015)

NIMH (2015)
Group author without abbreviation (Wellesley College, 2020) Wellesley College (2020)
  • No Author (sections 8.14 and 9.12)
    • Check to see if an organization or group authored the content. Use their name in place of a personal author. Use the full name each time if using an abbreviation would not be readily understood by your reader.

      Children with bipolar disorder are treated in similar ways as adults (National Institute of Mental Health, 2015).

    • If there is no organization, use the first few words of the title of the corresponding reference list entry. Put double quotation marks around titles of articles, chapters, and web pages; use italics for book titles, brochures, and reports.

      Polls show that black workers approve of labors unions more than white workers ("Black Workers Matter," 2016).

  • No Date (section 9.17): use n.d. in place of the date.

When to Include Page Numbers

For more detailed information see Publication Manual sections 8.23-8.36.

When paraphrasing, APA style does not require page numbers in the in-text citation. However, authors are encouraged to include page numbers if it will help the reader locate the relevant information in longer texts. Consult with your professor regarding the need for page numbers for paraphrased information.

For direct quotations, the author, year, and page number must be included. The page number can be given in parentheses at the end of the exact quotation or incorporated into the in-text citation. For one page, use "p." and for two or more pages, use "pp."

Newman (1994) concluded "sibling conflict is so common that its occurrence is taken for granted" (p. 123).

Such findings have prompted one researcher to conclude, “Sibling conflict is so common that its occurrence is taken for granted” (Newman, 1994, pp. 123).

For direct quotations from sources without page numbers, use paragraph numbers, if visibly numbered in the document. Otherwise, use the heading name and count the number of paragraphs after the heading to the paragraph containing the quotation.

(Smith, 2016, para. 1)

(Lee 2015, Discussion section, para. 4)

How to Format the Reference List (Section 9 of the APA Manual)

The reference list provides the full details on the sources you used in the research for your paper.

Each entry should include the following reference components:

  • Author
  • Publication Date
  • Title
  • Publication Source

See the examples in the left navigation for the required elements for each type of source. Continue reading below for details on formatting each reference component and ordering the reference list.

Formatting of Reference Components

For more information see: Publication Manual, section 9.7-9.12.

  • Invert the names of all authors (the last name followed by initials).
  • Keep author names in the order they appear on the document.
  • Put commas between the names.
  • Precede the last author with an ampersand (&).

    Dillard, J. P., & Shen, L.
    Guastello, D., Braun, S., Gutierrez, J., Johnston, K., & Olbinski, B.

  • For groups or institutions as authors, use their full name. Follow the name with a period.

    National Institute of Mental Health.

  • For works with no author, move the title to the author position. Follow the title with a period.

    Black workers matter.

For more information see: Publication Manual, sections 9.13-9.17.

  • Put the year the work was published or produced in parentheses.
    • For magazines, newspapers, and newsletters, give the year and exact date (month, month and day, or season) of publication, separated by a comma.

      (2016, January).
      (2016, March 7).
      (2016, Summer).

    • If the source has no date, put n.d. (meaning no date) in the parentheses.

      (n.d.).

  • End the component with a period.

For more information see: Publication Manual, sections 9.18-9.22.

  • Format of the Title Element:

    Factors influencing infants’ ability to update object representations in memory.

    Imaginary companions: An evaluation of parents as reporters.

    Heritage language education: A new field emerging.

    • For works that are part of a greater whole (e.g. journal articles, book chapters, etc.): do not italicize the title or use quotation marks, and do capitalize the first word of the title, subtitle, and any proper nouns.
    • For works that stand alone (e.g. books, webpages, etc.): italicize the title, and capitalize the first word of the title, subtitle, and any proper nouns.
    • Finish the component with a period.

For more information see: Publication Manual, sections 9.23-9.37.

  • Journals, magazines, blogs, and newsletters
    • Include the periodical title, volume number, issue number, and page range or article number.
    • Capitalize the major words of the publication title, italicize the title, and put a non-italicized comma after the title.
    • Put the volume number after the title.
    • Italicize the volume number.
    • Put the issue number for any publication with an issue number in parentheses immediately after the volume number with no space. Do not italicize the issue number.
    • Put the page range of the article after a comma after the issue number. Do not italicize the issue number.
    • End with a period and a DOI or URL as applicable (see sections 9.34-9.36)

      Psychological Science, 20(7), 805–812. https://doi.org/10.1111/j.1467-9280.2009.02377.x

  • Books and reports
    • New in the APA 7th edition: do NOT give the publisher's location
      • For works associated with specific locations (e.g. a conference paper), include the location: city; province, territory, or state using U.S. postal abbreviations for states; and country.
    • Give the publisher's name.
      • Publisher names change over time. Use the spelling and capitalization listed on the work you are citing.
      • Spell out the names of associations, companies, and university presses.
      • If the author is the same as the publisher, do not include the publisher in the reference (leave only as the author).
      • End the component with a period.

        Guilford Press.

Formatting and Ordering the Reference List

For more information see: Publication Manual, 2.12 and 9.1-9.52.

  • Start a new page for the reference list.
  • Capitalize, bold, and center the word References on the page.
  • Double space the entries.
  • Use the hanging indent feature of your word processor to indent the second and subsequent lines of the entries.

      Brownfield, G. (2015).
      Browning, R. (2013).

  • single-author: arrange chronologically (earliest one first)

    Brown, L. (n.d.).
    Brown, L. (2013).
    Brown, L. (2016).

  • same first author, but different co-authors: come after the single-author entries for the first author and then alphabetically by the last name of the second author (or third or fourth author, if the order of co-authors match exactly).

    Oliver, M. B. (2003).
    Oliver, M. B., Ash, E., & Woolley, J. K. (2013).
    Oliver, M. B., Ash, E, Woolley, J. K., Shade, D. D., & Kim, K. (2014).

  • same authors in the same order: arrange chronologically.

    Feigenson, L., & Carey, S. (2003).
    Feigenson, L., & Carey, S. (2005).

  • same author(s) and same date: add lowercase letters a, b, c, immediately after the date in the parentheses, assigning based on the month published. Dates with only a year on the publication are listed first.

    de Villiers, J., & Pyers, J. (1997a).
    de Villiers, J., & Pyers, J. (1997b, April).
