A reference to a psychological test (also called a measure, scale, survey, quiz, or instrument) follows the usual who-when-what-where format.
Here’s an example of a test you might have retrieved directly from a website:
Purring, A. (2012). Charisma and Tenacity Survey [Measurement instrument].
A test's name is a proper noun, so be sure to capitalize it in the reference.
In other cases, you may actually be citing the database record rather than the test. If you found a record for the test in a database, you can cite it, whether or not the record contains a link to the test itself:
Barks, H., & Howls, I. (2013). Directions of Generosity [Database record].
Retrieved from The McAdoo Database of Fictional Titles.
Or, perhaps you’ve used a test that is not available online. Not to worry, the format varies only in the "where" element. Use the first example above as your template, but replace “Retrieved from with the location and publisher (e.g., Petland, MD: E & K Press).
Although some tests are better known by their acronyms than by their full titles, the acronym is not included in the reference.* Rather, introduce the acronym at the first use in the body of the paper, as shown in the examples below.
In the body of your paper, be careful to write the name exactly as it appears in your reference. And here again, capitalize the test name, because it is a proper noun. However, capitalize the word survey (or instrument, quiz, etc.) only if it’s part of the test’s name:
“In this study, we used Purring’s (2012) Charisma and Tenacity Survey (CATS) rather than Barks and Howls’s (2013) Directions of Generosity survey.”
The abbreviation need not be introduced if the test name is mentioned only once. However, if the test name appears frequently in the paper (i.e., generally three or more times), define it the first time, and use the abbreviation consistently thereafter. Note also that the test names are not italicized when used in the text.
Finally, although you don’t need to include the author and date every time you mention the test by name, do include the author–date citation if you quote directly from the test or paraphrase it in any way.
If you’ve read this far, you’ve passed my test! Give yourself an A+.
*The exception is the rare case where the acronym is the only official name of the test (i.e., an official spelled-out title no longer exists, which is an uncommon occurrence; the most famous example is the SAT, which no longer has a spelled-out name).
