Tests and other measures fall into two categories:
- Readily accessible tests, scales, questionnaires, measures, etc. found in books and in journal articles (found by using specific databases: such as PsycINFO, CINAHL, and ERIC). The PsycTESTS database has the full-text of many instruments.
- Tests that are restricted and proprietary: those currently available are described and reviewed in the Mental Measurements Yearbook (MMY). Mental Measurements Yearbook is a useful tool for learning more about tests. The database includes reviews for more than 2,000 testing instruments. If you are looking for a specific measure by name, check MMY first to determine whether it is proprietary, who publishes it, and contact information.
For more information regarding tests and measurements, please see FAQ/Finding Information About Psychological Tests from the American Psychological Association.
