There are several possible ways to find the full-text of a test. It maybe was attached in a journal article by the author, or was provided as an appendix in a reference book. Please see below for different possibilities and the methods to locate it.
Tests in journal articles
Some journal articles include the test instrument that be discussed. Searching PsycINFO (or ERIC, if your topic is education or children related) may result some findings.
Sometimes, some books also include the full-text test instruments, check this database to see which book has the tests you want.
Please note: The links to "RefWorks' RefShare Interface" and "UT Arlington Web site" are not working any more, but you still can browse the section of "Collections examined". If you find an instrument you want, copy the book title and search it in our library's SearchBox to see whether our library has that book.
