Writing a research paper or academic essay often requires using sources to support your ideas. To give proper credit and avoid plagiarism, you need to cite those sources. One of the most common styles for academic writing is the APA format. Within this format, parenthetical citations are used to indicate the source of information within the text. Knowing how to do parenthetical citations in APA style correctly is essential for students, researchers, and professionals. This topic provides a detailed explanation of how to create APA-style parenthetical citations, with clear examples and rules that are easy to follow.
Understanding APA Parenthetical Citations
In APA format, parenthetical citations are one way to give in-text credit to the sources you reference. These citations appear inside parentheses and usually include the author’s last name and the year of publication. Sometimes, a page number is also required, especially when quoting directly from the source.
Purpose of Parenthetical Citations
Parenthetical citations help readers find the original source in the reference list at the end of your paper. They also provide transparency and help maintain academic integrity. The APA style emphasizes the author-date citation system, which helps readers see the age and relevance of a source.
Basic Format of APA Parenthetical Citations
The general structure for a parenthetical citation in APA format is:
(Author’s Last Name, Year)
When quoting directly, you should also include a page number:
(Author’s Last Name, Year, p. Page Number)
Examples:
- (Smith, 2020)
- (Johnson & Lee, 2021)
- (Brown, 2019, p. 45)
These citations refer to full entries in the reference list, where more details about the source are provided.
Multiple Authors in Parenthetical Citations
APA style has specific rules for citing sources with multiple authors. The number of authors determines how the citation is formatted.
Two Authors
Use an ampersand (&) between the names:
(Williams & Garcia, 2022)
Three or More Authors
Use the first author’s last name followed by ‘et al.’:
(Chen et al., 2021)
Even if the source has four, five, or more authors, APA 7th edition requires only the first name followed by ‘et al.’ in parenthetical citations.
Quoting vs. Paraphrasing
APA parenthetical citations are used both when quoting and paraphrasing. However, there are slight differences in how they are applied.
Direct Quotes
When you use the exact words from a source, include the page number:
Students often struggle with citation styles (Taylor, 2020, p. 12).
Paraphrasing
If you restate the information in your own words, the page number is optional but recommended:
Many students find citation formatting challenging (Taylor, 2020).
Multiple Works in One Citation
If you need to cite more than one source in a single parenthetical citation, separate them with semicolons and list them alphabetically by the first author’s last name:
(Anderson, 2018; Lee, 2019; Smith, 2020)
This method is useful when multiple sources support the same idea or claim.
Group Authors and Organizations
When citing a source written by a group or organization, use the full name of the group in the citation:
(World Health Organization, 2021)
If the organization’s name is long and appears multiple times, use an abbreviation after the first citation:
First citation:(National Institute of Mental Health [NIMH], 2022)
Subsequent citations:(NIMH, 2022)
Unknown Authors
Sometimes a source does not list an individual or group author. In that case, use the title of the work in italics or quotation marks, depending on the type of source.
Example with Book Title:
(APA Style Guide, 2020)
Example with topic Title:
(Effective Writing Tips, 2021)
Use italics for books and reports, and quotation marks for topics and webpages.
Special Situations in APA Parenthetical Citations
Same Author, Same Year
If you are citing multiple works by the same author published in the same year, add lowercase letters (a, b, c, etc.) after the year:
(Martin, 2020a)and(Martin, 2020b)
Make sure these labels match the order of the sources in your reference list.
Secondary Sources
When you are citing a source that was mentioned within another source (a secondary source), APA recommends identifying both, but citing only the source you actually read.
(Johnson, 2005, as cited in Lee, 2021)
Only include Lee (2021) in the reference list since that’s the source you accessed.
Tips for Using Parenthetical Citations in APA Style
- Always place the citation before the period of the sentence.
- If your sentence already includes the author’s name, only add the year in parentheses.
- Do not repeat the citation multiple times within the same paragraph unless needed for clarity.
- Double-check the spelling and date of every citation to match your reference list exactly.
