A self-report test that presents many questionnaire items to two groups that are known to be different is called empirically keyed test.
Self-report tests are helpful since they have high levels of dependability, meaning the results are valid and trustworthy. They are also thought to be more affordable than other psychological exams, which is another factor that makes them advantageous and beneficial.
In a self-report test, participants read the question and choose their own response to it without the help of a researcher or other participant. Any approach that involves asking a participant about their feelings, attitudes, opinions, etc. is a self-report method.
