This guide describes major resources used to locate materials on psychological or behavioral instruments as related to the health sciences. Please note tests can also be referred to as inventories, measurements, psychometric tests, questionnaires, scales, surveys, and tools.
Finding the full test or its related literature is not always easy and often requires checking several resources including directories, textbooks, theses, and databases.
The resources described in this guide may help you find and acquire the actual test instrument or locate the literature that discusses the use and validity of the test.
Sometimes it may be necessary to contact the author or creator of the test to gain access. Often a professional credential is required to administer the test.
Psychological tests are standardized measures of a particular psychological variable.
Tests can be purchased commercially or unpublished tests can be found in the literature using one of several resources.
