Example – commercially published test, citing its manual
Scroll down for associated examples
Psychological tests may be published commercially (usually for use in practice), or non-commercially by the test’s creator (usually for research use), perhaps within a journal article or on the test creator’s website.
If possible, cite the test by its supporting literature, such as a publication it first appeared in or which is associated with it: If the test simply appears within a journal article, just cite that article in the usual format. If you obtain the test from the test creator’s website, it may be cited as the website or they may request you to make certain citations (e.g. to a particular journal article about it). If the test is commercially-produced, cite the test’s manual like a book.
