Additional points

Like any good literature search, you will not always find the article you want for your research. The same principle applies to locating specific tests. You will need to be flexible about the sources available. If you are unable to find a test or measure always ask a librarian for assistance.

Give yourself enough time to search, review, and find an actual test. Also determine whether the test is copyrighted and whether you are qualified to administer the test.

It is tempting to want to develop your own test to suit your needs. However, there are many factors to consider such as sampling, scoring, etc. Do not re-invent the wheel. Perform a thorough search using the resources listed here to see if a tool already exists that may suit your needs.

Remember to always cite your sources. For example, consult the Publication Manual of the American Psychological Association, 6th ed. or a brief guide:

You have an ethical responsibility to use tests wisely. You should select tests that meet the purpose for which they intended and for the appropriate population. You should select tests that attempt to make them as fair as possible for test takers. You should inform test takers about their rights, responsibilities, and risks and benefits in taking part in any study, treatment, or program.
