Look for articles that discuss the test in the database PsycInfo. Cinahl or PubMed databases may help if your topic covers health or medical issues. Check the bibliography or reference list of your articles or books for further sources of information on a test. MMY or HAPI databases may give you contact information for the tests or a vendor name to contact about a test/measure.
Search in the library catalog for "psychological tests" as a Subject Heading.
Check the author’s website. If you are also searching via Google Scholar (set preferences) or Advanced Google, you may be asked to pay or login for some sources. If you are checking from home, then you can set preferences in Google Scholar for the UCF Library and login with your NID and NID password. Always check to see if UCF Libraries has the journal article/book you are searching for, do not pay for an article. You can InterLibrary Loan a copy of the article via UCF Libraries webpages (http://library.ucf.edu/ILL/). Google Scholar is only one web source, make sure you use others.
