You can use ERIC to find information about tests. Sometimes you can retrieve articles containing a copy of the test or measurement instrument itself.
(NOTE: TESTLINK IS NOT FULLY FUNCTIONAL ON SUNDAYS WHILE ETS UPLOADS NEW INFORMATION INTO THE DATABASE)
You can use PsycINFO to find information about tests and perhaps the tests themselves. Sample search:
Search by title (test name), keyword, or phrase describing the atribute(s) you wish to measure.
Sample topic search: Stress AND appended
Limit the word Stress to the subject field (if desired)
Use the word, "appended" to bring up articles in which the test is "appended." You may try other similar terms as well.
Under "Limit Your Results--Classification Codes" (bottom left)- select "Clinical Psychological Testing" and/or "Personality Scales and Inventories" or another code that is more descriptive of your desired outcome.
Note: Even if a test is not appended, this is a good way to find the names of tests, which you can then look for in books or other databases.
