It can be challenging to find the full text of tests, instruments, and measures. This is due to the fact that most well-known tests are commercial property and must be purchased. "Unpublished" tests are the ones you are much more likely to find in full text. These tests are the ones that have been published as part of a research article or in a handbook of measures.
The following resources can help you locate research measures:
Communication Research Measures (provided by Prof. James C. McCroskey, University of Alabama, Birmingham
Directory of Unpublished Experimental Mental Measures, multivolume set.
Psychological Tests for Students' Use
(maintained by Prof. Ron Okada, Faculty of Health, York University, Toronto, Ontario)
The SAGE handbook of personality theory and assessment, Vol 2: Personality Measurement and Testing / edited by Gregory J. Boyle, Gerald Matthews, Donald H. Saklofske.
