Properly citing academic journal articles is a cornerstone of academic integrity and scholarly communication. The American Psychological Association (APA) style is widely adopted in social sciences, education, and psychology. The 7th edition, released in 2019, brought several updates designed to simplify and modernize the referencing process. Understanding these guidelines ensures your work is credible, avoids plagiarism, and allows readers to easily locate your sources.
Key Components of an APA Journal Citation
Every APA journal citation, whether in your reference list or as an in-text citation, needs specific pieces of information. For the reference list entry, the core elements are:
- Author(s): Last name, followed by first initial(s).
- Year of Publication: In parentheses.
- Article Title: Sentence case capitalization.
- Journal Title: Title case capitalization, italicized.
- Volume Number: Italicized.
- Issue Number: In parentheses, not italicized, following the volume number.
- Page Range: Start and end page numbers.
- DOI (Digital Object Identifier): A persistent link to the article.
Let's break these down with examples.
Author(s)
List authors in the order they appear on the article. Use an ampersand (&) before the last author's name.
- One Author: Smith, J. D.
- Two Authors: Smith, J. D., & Jones, A. B.
- Three or More Authors: For articles with 20 or more authors, APA 7th edition simplifies this by listing the first 19 authors, followed by an ellipsis (...) and then the final author's name. For fewer than 20 authors, list all of them.
Example (3-19 authors): Williams, R. T., Brown, S. L., Garcia, M. P., Davis, L. K., Miller, C. J., Wilson, P. A., Taylor, E. R., Anderson, K. M., Thomas, B. L., Harris, J. P., Martin, D. A., White, F. E., Lee, G. H., Walker, S. N., Hall, R. P., Allen, J. M., Young, T. L., King, V. B., & Wright, C. D. Example (20+ authors): Adams, B. A., Baker, C. D., Clark, E. F., Davis, G. H., Evans, I. J., Foster, K. L., Green, M. N., Harris, O. P., Jackson, Q. R., Kelly, S. T., Lewis, U. V., Moore, W. X., Nelson, Y. Z., Parker, A. B., Quinn, C. D., Roberts, E. F., Scott, G. H., Thompson, I. J., Underwood, K. L., ... Zimmerman, P. Q.
Year of Publication
This is straightforward. Just the year the article was published, enclosed in parentheses.
- (2021)
- (2020)
Article Title
Use sentence case capitalization. This means only the first word of the title, the first word of a subtitle (if any), and proper nouns are capitalized.
- Correct: The impact of social media on adolescent self-esteem.
- Correct: A meta-analysis of cognitive behavioral therapy: Efficacy and moderators.
- Incorrect: The Impact Of Social Media On Adolescent Self-Esteem.
Journal Title, Volume, Issue, and Page Range
The journal title is italicized and uses title case capitalization. The volume number is also italicized. The issue number, if present, follows the volume number in parentheses and is not italicized. The page range indicates where the article can be found within the journal.
- Journal Title: Journal of Applied Psychology
- Volume: 35
- Issue: (2)
- Page Range: 112-135
DOI
The DOI is crucial for online articles. It's a unique identifier that helps readers find the exact article, even if the URL changes. APA 7th edition requires the DOI to be presented as a hyperlink.
- `https://doi.org/10.1037/a0020001`
Putting It All Together: The Reference List Entry
Now, let's combine these elements into a full reference list entry.
Basic Format:
Author, A. A., Author, B. B., & Author, C. C. (Year). Title of article. Title of Periodical, Volume(Issue), pages. DOI
Example 1: Article with a DOI
Suppose you're citing an article by Lee, Chen, and Rodriguez published in 2022 in the Journal of Educational Psychology. The article title is "Enhancing student engagement through project-based learning." The volume is 114, issue is 3, and it spans pages 450-465. The DOI is 10.1037/edu0000789.
Your reference list entry would look like this:
Lee, S. H., Chen, L. W., & Rodriguez, M. A. (2022). Enhancing student engagement through project-based learning. Journal of Educational Psychology, 114(3), 450-465. https://doi.org/10.1037/edu0000789
Example 2: Article without a DOI (less common for recent articles)
If an article doesn't have a DOI, and it was accessed online, you'll typically include the journal homepage URL. If it's from a print journal, you just end the citation after the page numbers.
Suppose you found an older article by Davis from 2010 in the Review of Educational Research, volume 80, issue 1, pages 100-120. It doesn't have a DOI.
Davis, P. R. (2010). The role of metacognition in learning. Review of Educational Research, 80(1), 100-120.
In-Text Citations
In-text citations briefly identify the source within your text, usually including the author's last name and the publication year. They direct the reader to the full citation in your reference list.
Parenthetical Citations
This is when the citation appears at the end of a sentence or clause.
- Research indicates a strong correlation between self-efficacy and academic performance (Bandura, 1997).
- Several studies have explored the benefits of early childhood education (Smith & Jones, 2020).
Narrative Citations
This is when you incorporate the author's name into the text as part of the sentence.
- Bandura (1997) argued that self-efficacy is a crucial determinant of motivation and achievement.
- Smith and Jones (2020) found that early interventions significantly impact long-term educational outcomes.
Citing Multiple Authors In-Text
- Two Authors: Always cite both names every time.
(Smith & Jones, 2020) Smith and Jones (2020) found...
- Three or More Authors: For three or more authors, list the first author's last name followed by "et al." and the year, starting with the first citation.
(Williams et al., 2021) Williams et al. (2021) suggested...
Citing Direct Quotations
When you use someone's exact words, you must include the page number(s) where the quote can be found.
- Parenthetical: The study concluded that "students who engage in collaborative learning demonstrate higher levels of critical thinking" (Johnson, 2019, p. 55).
- Narrative: Johnson (2019) noted that "students who engage in collaborative learning demonstrate higher levels of critical thinking" (p. 55).
If there are no page numbers (e.g., some online-only articles), use paragraph numbers or section headings.
Common Issues and Tips
- Missing Information: If a piece of information (like the issue number or DOI) is genuinely missing and cannot be found, omit it. Do not create it.
- Capitalization: Adhere strictly to sentence case for article titles and title case for journal titles.
- Italics: Remember to italicize the journal title and the volume number.
- DOIs vs. URLs: Prioritize DOIs. If an article has both a DOI and a URL, use the DOI. If it has neither but was accessed online, use the URL of the journal's homepage, not the direct link to the PDF.
- Databases: When citing articles retrieved from academic databases (like PsycINFO, JSTOR, or ERIC), do not include the name of the database or the URL for the database itself. If the article has a DOI, use that. If it doesn't, and you found it through a database search but it's also available elsewhere with a DOI, use that DOI. If it has no DOI and no stable URL, you can omit the URL.
- Consistency: The most important thing is consistency. Once you've established a format for a particular type of source, stick to it throughout your reference list.

When to Use "et al." for In-Text Citations
APA 7th edition simplifies in-text citations for sources with three or more authors. You will use "et al." for every citation, regardless of how many times you cite the source.
- Example: (Thompson et al., 2023) or Thompson et al. (2023) found...
This applies to all parenthetical and narrative citations.
Handling Articles with No Author
If an article has no author, begin the citation with the title of the article. Use sentence case for the article title and italicize the journal title. The year follows the title.
- Example: The future of artificial intelligence in education. (2021). Educational Technology Review, 29(1), 45-60.
When to Use Paragraph Numbers
For sources that don't have page numbers (like some online articles, websites, or interviews), you can use paragraph numbers. Indicate this with "para." followed by the number.
- Example (direct quote): The author stated that "digital literacy is now a fundamental skill" (Smith, 2020, para. 7).
Final Thoughts on Accuracy
Mastering APA journal citation is an ongoing process. Referencing the official Publication Manual of the American Psychological Association (7th ed.) is always the most authoritative source. Practicing these formats regularly will build your confidence and ensure your academic work is presented professionally and ethically.
