Looking for a questionnaire for a personality trait or other “individual difference” measure?
The International Personality Item Pool (IPIP) is an online collection of valid and reliable public domain tests. Look up a trait and then view a short list of items that have been shown to discriminate among levels of that construct. Add a Likert scale to the items and you have a questionnaire.
How to cite the IPIP? Answer is:
Name of Scale. Retrieved July 34, 2029, from International personality item pool: A scientific collaboratory for the development of advanced measures of personality traits and other individual differences: http://ipip.ori.org/
The full text of these tests and measures is often not included as a PDF in PsycTests.
If there is no PDF, look for a "Test Location" field which will tell you where to find a copy of the test in the journal article or book listed at the top of the record. (or there may just be a "Permissions" field that tells you to contact the author or publisher.
In order to best find your test topic, limit your search term to TI (Title) or SU (Subjects). This eliminates the tests where your topic is just one item in a questionnaire about something less relevant.
The correct APA Citation will be at the top of each test PDF. Example:
