Is the test published or unpublished?
Published simply means that it is available through a publisher, usually for a price. Find information, including publishers, about these tests in Mental Measurements Yearbook with Tests in Print or the ETS Test Collection Database. Or use a search engine, such as Google, to search for the test and find publication information about a test on a publisher's website.
Unpublished tests are often research instruments that can be found in journal articles, PsycTESTS, and online.
Researchers may post the survey or test they used on a website. Use a search engine, such as Google, and put quotation marks around the title of the test. The quotation marks will make your search more precise.
Possible last method of accessing the full text of a test or survey? Contact the author. Many authors are university professors. You can find their contact information in their published articles or the university's website. Send them an email inquiring about using their survey. Let them know you are a student or researcher working on a project and would like to look at or use their survey. The more detail you provide the more helpful they will likely be.
