APA In-text Citations

Basic Format:
(Author's Last Name 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 Shavers (2007), "Direct quote" (p. #).
  • Shavers (2007) found that "Direct quote" (p. #).
  • [Some other introduction] "Direct quote" (Shavers, 2007, p. 1021).

 

If you're directly quoting more than 40 words...

Use a blockquote. Block quotes don't need quotation marks, but are indented 1/2" as a visual cue of a citation. The in-text citation in parentheses goes after the punctuation of the quotation.

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)

Pro Tip: Use direct quotes sparingly! Research cited in an APA paper is focused more on the synthesis of findings from a variety of research studies, and less about the exact phrasing or argument of an individual.

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, among others (p. 1016).

I'm citing...

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)

If the work has no author, use a shortened form of the title in parentheses. Note that titles are capitalized in in-text citations.

Book with no author: (Interpersonal Skills, 2019)

Article with no author: ("Understanding Sensory Memory," 2018)
