Medicine: Tests and Measures
The resources here will help you find tests and measures that you may consider using in your own research. Mental Measurements Yearbook with Tests in Print primarily indexes published, commercially available tests with information on how to acquire them. PsycTests primarily covers unpublished tests (often including the full text of the test itself). Both offer varying information regarding validity and reliability of tests referenced. PsycInfo is another great place to look for test information in scholarly works that used them, though the full test is often not available there.
