APA Style in 6(ish) Minutes

About APA Style

This guide is a quick introduction to the American Psychological Association (APA) Style for references and citations. Be sure to consult the Publication Manual of the APA or the APA Style website for detailed standards and procedures. 

In-Text Citations

When you reference another source use an in-text citation in the body of your paper. 

Basic Format:
(Author's Last Name(s) or Organization, Year).

I'm using...

If you're quoting the exact words of someone else, introduce the quote with an in-text citation in parentheses. Any sentence punctuation goes after the closing parenthesis.

  • According to Brown (2019), "milk chocolate is the best kind of candy" (p. 1021).
  • Brown (2019) found that "milk chocolate is the best kind of candy" (p. 1021).
  • Although experts have argued about this for decades, "milk chocolate is the best kind of candy" (Brown, 2019, p. 1021).

 

If you're directly quoting more than 40 words, use a blockquote. Block quotes don't need quotation marks. Instead, indent the text 1/2" as a visual cue that you are citing. The in-text citation in parentheses goes after the punctuation of the quote.

Shavers (2007) study found the following:

While research studies have established that socioeconomic status influences disease incidence, severity and access to healthcare, there has been relatively less study of the specific manner in which low SES influences receipt of quality care and consequent morbidity and mortality among patients with similar disease characteristics, particularly among those who have gained access to the healthcare system. (p. 1021)

Tip: Use direct quotes sparingly! Focus on summarizing the findings from multiple research studies. In the sciences and social sciences, only use the exact phrasing or argument of an individual when necessary.

Paraphrasing or summarizing the main findings or takeaways from a research article is the preferred method of citing sources in an APA paper. Always include the last name of the author(s) and the year of the article, so your reader can find the full citation in the reference list.

According to Shavers (2007), limitations of studying socioeconomic status in research on health disparities include difficulties in collecting data on socioeconomic status and the complications of classifying women, children, and employment status.

 

In-text citations differ depending on the number of authors listed for a work, and if there is a group author.

I'm citing a work with...

You only need the author's last name and the year.

(Abrams, 2018)

Connect both authors' last names with & (ampersand) and include the year.

(Wegener & Petty, 1994)

If there are 3 or more authors use et al., which means "and others."

(Harris et al., 2018)

First time with an abbreviation:

(Centers for Disease Control and Prevention [CDC], 2019)

Then all subsequent citations: (CDC, 2019)

References page

Include the complete citation at the end of your paper in a references section. References are organized by the author's last name in alphabetical (A-Z) order. Use an hanging indent to separate each list item.

Basic Format:
Author, A. A., & Author, B. B. (Date). Title of the work. Source where you can retrieve the work. URL or DOI if available

I'm citing a...

  1. Author(s). Note: List each author's last name and initial as Author, A. A., Author, B. B., & Author, C. C. Use an ampersand (&) before the final author's name. Read more from the APA Style website if there are 21 or more authors.
  2. (Year).
  3. Title of the article. Note: For works that are part of a greater whole (e.g. articles, chapter), use sentence case. Only the first word of the title and subtitle and proper nouns are capitalized.
