What is a psychological test?

Psychological tests are assessment tools frequently used in many fields of psychology. They are used to measure a range of variables related to psychology, such as intelligence, personality, or attitudes and so on, and they usually involve the analysis of a sample of behavior. Tests are a standardized measurement instrument - they may be called an inventory, questionnaire, index, scale, checklist, profile or a test.

The Library does not hold copies of tests - tests are published commercially and are often restricted to trained or registered professionals - but we can help you locate test reviews and identify suitable tests for your research.
