During your research you may find you would like to use psychological tests or measures. These are instruments that allow researchers to measure a particular variable such as memory, intelligence or personality. The UK's Institute of Work Psychology defines a test as:
"A brief sample of someone's behaviour, obtained under standard conditions, and scored according to a fixed set of rules that provide a numeric score or classification." (Myors & Carstairs, 2001).
Tests usually fall into two types:
Many tests (especially commercially available ones) require you to be professionally trained and accredited in order to use them. I.e. many of the commercial suppliers will only supply tests to clinical professionals. It can be challenging to find the full text of tests, instruments, and measures. This guides provides a starting point to finding these types of resources.
If you'd like to know more about psychological testing generally, Professional Bodies are a good place to start.
Alternatively, check the websites of these providers:
Buros Institute of Mental Measurements makes a lot of its material available on its website free-of-charge or for a small fee.
ETS Test Collection is a not for profit Educational Testing Service.
Pearson Assessment provide many products adapted to UK needs. The focus is on Psychology, Allied Health and Education. Each test is classified with a Qualification Code. Before you can purchase material from them, you have to be registered. Your level of qualification governs the tests they will sell to you.
Many tests and questionnaires can be found in books, journal articles and databases. It may be possible for you to use them or adapt them for your own work, with the permission of the author.

For example if you wanted to find a questionnaire on body-image in a database you could perform the following search:
"body image" in SU Subjects and "test construction" in SU Subjects.
You may be able to find psychological tests and measures using databases such as PsycINFO and CINAHL Plus.
The following tabs provide step by step instructions on how to do so on each database. You should be aware that full tests are not available for all records.

Alternatively, undertake your Subject Term/keyword search, and then refine the results using the Source Type refine option ( Click on ‘Show More’ to display the ‘Research Instruments’ tick box).
Search using the Instrumentation Field. Enter the specific name of the research instrument into the search box and select ‘Instrumentation’ from the drop-down list. Click Search.
