Mastering Apa Case Study Citations A Step By Step Guide For Clear And Accurate References 2

Accurate citation is the backbone of academic integrity. In psychology, education, and social sciences, the American Psychological Association (APA) style sets the standard for referencing sources—including case studies. Yet many students and researchers struggle with formatting case study citations correctly. Mistakes in punctuation, author order, or date placement can undermine credibility and result in lost points or rejected submissions. This guide breaks down the process into manageable steps, ensuring your references are consistently precise and professionally formatted.

Understanding APA Case Study Citation Basics

In APA 7th edition, case studies are treated as either standalone publications (e.g., published in journals) or as part of larger works (e.g., textbooks or edited volumes). The key to correct citation lies in identifying the source type and applying the appropriate structure. A typical reference includes four core components: author(s), publication year, title of the case study, and source information (journal, book, or database).

The general format for a journal-published case study is:

Author, A. A., & Author, B. B. (Year). Title of case study. Journal Name, Volume(Issue), page range. https://doi.org/xx.xxxxxx

If the case study appears in an edited book, the format adjusts slightly:

Author, A. A. (Year). Title of case study. In E. Editor (Ed.), Title of book (pp. xx–xx). Publisher.

Accuracy in capitalization, italics, and punctuation is non-negotiable. Titles of case studies use sentence case—only the first word and proper nouns are capitalized. Journal names, however, are in title case and italicized.

Tip: Always verify whether your case study has a DOI. If available, include it at the end of the citation without a period.

Step-by-Step Guide to Formatting Case Study Citations

1. Identify the Source Type: Determine if the case study is from a journal, book chapter, institutional repository, or online platform like Harvard Business Review.
2. Gather All Necessary Information: Collect author names, publication year, full title, journal or book title, volume and issue numbers (if applicable), page range, and DOI or URL.
3. Format the Author Names: List last names followed by initials. Use an ampersand (&) before the final author in multi-author entries.
4. Apply Correct Title Capitalization: Use sentence case for the case study title; capitalize major words in the journal or book title.
5. Italicize Proper Elements: Italicize the journal name and volume number—but not the issue number, which goes in parentheses immediately after.
6. Add the DOI or URL: Present DOIs as hyperlinks starting with https://doi.org/. For URLs without DOIs, provide the direct link without \"Retrieved from\" unless a retrieval date is needed.

Example: Journal-Published Case Study

A peer-reviewed case study titled \"Cognitive Behavioral Therapy in Adolescent Depression: A Case Study\" by L. M. Reyes and T. J. Kim, published in 2022 in the Journal of Clinical Psychology, Volume 78, Issue 4, pages 567–579, with DOI 10.1002/jclp.23401, would be cited as:

Reyes, L. M., & Kim, T. J. (2022). Cognitive behavioral therapy in adolescent depression: A case study. Journal of Clinical Psychology, 78(4), 567–579. https://doi.org/10.1002/jclp.23401

Example: Case Study in an Edited Book

If the same case study appeared in a textbook edited by D. A. Patel titled Modern Approaches to Mental Health Treatment, published by Sage Publications in 2021, on pages 112–125, the citation would be:

Reyes, L. M. (2021). Cognitive behavioral therapy in adolescent depression: A case study. In D. A. Patel (Ed.), Modern approaches to mental health treatment (pp. 112–125). Sage Publications.

Common Pitfalls and How to Avoid Them

Missteps in APA citations often stem from overlooked details. Here are frequent errors and how to prevent them:

Error	Correct Approach
Incorrect author formatting: “Reyes, Lisa M.”	Use initials only: “Reyes, L. M.”
Using “et al.” in reference list entries	List up to 20 authors; use ellipsis only after the 19th
Capitalizing all words in article titles	Use sentence case: only first word and proper nouns capitalized
Omitting italics for journal name and volume	Italicize both: Journal Name, Volume
Adding “Retrieved from” before DOIs	DOIs stand alone: https://doi.org/xx.xxxxxx

Tip: When in doubt, consult the official APA Publication Manual (7th ed.) or the Purdue OWL APA guide for authoritative examples.

Real Example: Applying the Guidelines in Practice

Sophia Tran, a graduate student in clinical psychology, was preparing a literature review that included a pivotal case study on PTSD treatment in veterans. She found a relevant case titled \"Narrative Exposure Therapy with Combat Veterans: A Longitudinal Case Analysis\" by M. R. Ellison and C. D. Nguyen, published in 2020 in the Journal of Traumatic Stress, Volume 33, Issue 2, pages 201–210, with DOI 10.1002/jts.22503.

Initially, Sophia wrote:

Ellison, M. R., & Nguyen, C. D. (2020). Narrative exposure therapy with combat veterans: A longitudinal case analysis. Journal of Traumatic Stress, 33(2), 201–210. doi:10.1002/jts.22503

She missed two critical elements: italics for the journal and volume, and the proper DOI format. After reviewing APA guidelines, she corrected it to:

Ellison, M. R., & Nguyen, C. D. (2020). Narrative exposure therapy with combat veterans: A longitudinal case analysis. Journal of Traumatic Stress, 33(2), 201–210. https://doi.org/10.1002/jts.22503

This small correction ensured her paper met academic standards and demonstrated attention to detail—a trait valued in scholarly writing.

“Precision in citation reflects rigor in research. A single misplaced period can distract readers and raise questions about overall credibility.” — Dr. Alan Prescott, Academic Writing Consultant, University of Michigan

Checklist for Perfect APA Case Study Citations

• ☑ Journal or book title in title case and italicized
• ☑ Volume number italicized; issue number in parentheses, not italicized
• ☑ Page range included with en dash (–)
• ☑ DOI formatted as https://doi.org/xx.xxxxxx

• ☑ Retrieval dates included only for sources designed to change over time (e.g., wikis)

Frequently Asked Questions

How do I cite a case study without a DOI?

If no DOI is available and the case study is from a library database or print source, omit the DOI. For online sources without DOIs, include the URL of the journal’s homepage or stable link. Do not use database URLs (e.g., EBSCOhost).

Can I cite a case study from a course pack or internal document?

Yes, but treat it as an unpublished manuscript or personal communication if it’s not publicly accessible. If it’s part of a university-released course pack, cite it as:

Author, A. A. (Year). Title of case study [Unpublished case study]. Department Name, University Name.

What if the case study has no listed author?

Begin the citation with the title in place of the author. Maintain sentence case and italicize the title as you would a standalone work. Example:

Crisis intervention in schools: A case study. (2019). School Psychology Quarterly, 34(1), 45–52. https://doi.org/10.1037/spq0000301
