Tests, instruments, and scales focus on measuring outcomes. Sometimes you can view a test because it has been published in a journal article or dissertation. However, tests are copyrighted. If you cannot find the full-text of the test via a database such as PsycTESTS or from journal articles, you may have to purchase the test directly from the publisher.
These two tools are recommended for those who need to create a survey or questionnaire with more than a few questions. There are a number of other apps and survey options online for the shorter surveys.
