What is test-retest reliability?
Date:

Test-retest reliability refers to the consistency in the responses of participants throughout time. Often, participants are measured with time between the measurement occasions. If we assume that a characteristic is stable, the person should get similar scores with similar measurements. If the correlation between both tests is high (at least .70), a test has a high reliability.
