There are two main forms of in-text citations: parenthetical and narrative.
Depending on the source, in-text citations may look slightly different depending on how many authors are credited.
The table below provides examples of how to write citations for various author types.
Table 1
Formatting of Citations
Author Type | Parenthetical Citation | Narrative Citation |
One Author | (Nguyen, 2019) | Nguyen (2019) |
Two Authors | (Nguyen & Martin, 2020) | Nguyen and Martin (2020) |
Three or More Authors | (Salas et al., 2018) | Salas et al. (2018) |
Group Author with Abbreviation First Citation Subsequent Citations |
(World Health Organization [WHO], 2020) (WHO, 2020) |
World Health Organization (WHO, 2020) WHO (2020) |
Group Author Without Abbreviation | (Harvard University, 2019) | Harvard University (2019) |
The APA manual also outlines the six steps to creating a citation in the image presented in Figure 1.

APA's Six Steps to Proper Citation
When citing multiple works within a parenthetical citation, list each citation in alphabetical order separated by semicolons.
When there are multiple works by the same author, order citations by the year of publication. Citations with no date go first, followed by works with dates presented in chronological order (earliest to latest). For entries with the same year and same author, designate a letter that corresponds with the reference entry.
When citing specific sections of a source, provide the author and date followed by the information on the specific section. The reference list should include an entry for the entire source. Citing specific sections of a source may be done when paraphrasing or when directly quoting. See Sections 8.13 and 8.23–8.27 of the APA Manual (7th ed.) for more information.
The specific section may be a page number, paragraph, chapter, etc. For example:
An author is unknown when no author is listed. For example, religious works such as the Bible contain unknown authors. Anonymous authors are specifically listed and identified as “anonymous" within the work.
When an author is unknown, use the title of the work as the author in in-text citations. Italicize the title if it is italicized in the reference entry. Use quotation marks if it is not italicized in the reference entry. For example:
For anonymous authors, replace the author with “Anonymous" such as: (Anonymous, 2017).
In works where the source has been translated, reprinted, republished, or reissued, the in-text citation must contain both the original publication date and the publication of the update/adaptation. The years are separated by a slash, with the earliest year first. For example:
As a general rule, include the author and year in every occurrence. However, when referencing the same work in a narrative citation within one paragraph, the date may be omitted after the first occurrence. However, if the reference is interrupted by another source or citation, it must be cited again. The source must also be cited again at the start of a new paragraph. For more information, see Section 8.16 of the APA Manual (7th ed.).
Citations serve a couple of purposes to (1) support your point or argument and (2) give credit to the work of others. Knowing how to format citations as described in the sections above is important, but do not forget to keep in mind when to include citations and what the purpose of the citation is. Here are some basic tips to get started:
Declarative statements occur when you are (1) making statements of fact, (2) drawing on established knowledge (specific theories, modalities, historical knowledge), (3) making an association that has been studied in the literature, and (4) making references to “the literature", “researchers", “studies." In addition, common field-specific content still requires citations. For instance, you may have worked in a particular field for a long time and some knowledge may seem “general" to you, but it likely still needs to be cited for individuals outside of your field of expertise. However, if the general public is familiar with the concept (even outside the field) citations may not be needed. For example, "Facebook is a social media platform" would not require a citation because this is common knowledge to a large majority of people in different fields. However, the sentence "Using social media platforms like Facebook increases the likelihood that an individual will experience depression" would require a citation.
Examples
Interpretive statements do not need to be cited. They represent how you are connecting the cited literature to your overall discussion. Sometimes, depending on the requirements of the assignment, these may be your own personal thoughts. Other times you may use interpretive statements to convey the connection between a cited source and your point. Interpretive statements may also offer critique, perhaps explaining how a cited study cannot be adequately generalized because its sample included only males or mostly white participants. These critiques also represent interpretive statements that come from you and do not need to be cited.
