PSYC 571: Tests and Measurements (Harrisburg)

Links to databases and other resources for finding psychological testing instruments. Also provides explanations, search tips, and other "words to the wise" for locating and using tests.


Identifying the best tests for your thesis or research project can be challenging. There may be many tests available, each for different purposes and populations, and each of different levels of quality.

One place to start is by exploring tests that are widely used and have been peer-reviewed by other researchers. Below are some steps and resources.

Step 1: Explore Tests That Are Commonly Used and Peer Reviewed

NOTE: These sources do NOT provide copies of tests. Instead, they give you basic information such as the test name, purpose, population, scoring system, validity, price, and publisher.

Step 2: Identify Additional Tests (if needed)

You can identify additional tests using these resources. Note, however, that reliability/validity information and the full text of the test may not be freely available for every item. 

Search Tips

Finding the best tests and measurements for your project can be challenging. As you work through the steps above, here are some general tips:

    “Truncate” (*) your keyword searches so that library databases will search for all forms of the root word
    • For instance, assess* will find books and articles that have “assessment” or “assessing” in the title
  • Try related and broader words, especially if you are finding too few results.
    • For instance, if you’d like to measure problem-solving ability in 16 to 21-year olds, try both "adolescents," "high school," and related words. Also, you can try "intelligence" (a broader term) instead of “problem-solving ability”
  • Carefully note every clue you find regarding your tests, their authors, and their publishers, including:
    • Abbreviations, popular names, and “official” or spelled-out names of your tests
    • Names of all authors who were involved in the development of the tests
    • Corporations that published the tests, or universities where the tests' authors work
    • Alternative versions and new editions of the tests 
  • On the internet, many free versions of tests are edited or shortened -- they are not the complete, original tests that you are expected to use. Be cautious about using them
