Tests and Measurements in the Behavioral and Social Sciences

The resources listed in this guide are for information only, and do not constitute an endorsement of any specific instrument or legal advice regarding copyright.

Tests and measurements are typically used for research and assessment. They can be referred to as surveys, instruments, questionnaires, scales, tests, or measures. 

There are several ways to identify test instruments, however, finding actual tests and scoring information can be a time-consuming and challenging task. There is no single source that will provide free, full-text copies of a test instrument. 

Tests and measures are often categorized as published or unpublished. Published tests are commercially available for purchase from a publisher, and there may be qualifications for who can administer the test.

Unpublished or noncommercial tests are usually referred to in journal articles, books dissertations, reports, etc., and you may need to contact the author or copyright holder to obtain the entire test or for permission to use it.

One important decision you will face in the research process is whether to use an existing instrument, to modify an instrument, or to create your own instrument from scratch. The latter two will require extensive testing to ensure the reliability and validity of the instrument. This is an important consideration that should be discussed with your advisor or committee.

Be wary of test instruments you find on the web unless they come from an authoritative source. Most publishers do not make their instruments widely available due to the potential for compromising the validity/reliability of the test, and improper administration/evaluation by unqualified persons. Instruments may also be posted on the web by those who have no training in measurement or assessment techniques. Critically evaluate any unpublished test you find.
