Question

Quizplus · Accepted Answer

Test-retest reliability refers to how consistent the results of a measure are over time when the same measure is administered to the same participants on two or more occasions. Therefore, the best choice is when participants fill out the same measure on more than one occasion, as this is the only option that fits the definition of test-retest reliability. The other options may refer to other forms of reliability (such as inter-rater reliability or parallel forms reliability) but are not specifically linked to test-retest reliability.
