Measuring Intimate Partner Violence Victimization and Perpetration: A Compendium of Assessment Tools by Often a test or measure used for dissertation research is reproduced in the dissertation, if it is not a commercial test.
The websites of research centers or academic departments may distribute tests. Generally these will come up with a Google search by test name, but the following is a list of sites with collections of tests.
Unfortunately, some tests are sold by commercial vendors that place severe restrictions on their use. These are almost impossible to obtain by interlibrary loan because they are generally not sold to libraries, and often quite expensive. If the test you are seeking falls into this category, you will have the most success searching the other resources listed on this page for similar tests.
How to tell if it is a commercial test?
Often, if you Google the title of a commercial test, you will find the website of the vendor that sells it. Alternatively, you may search:
