Test-retest reliability is a specific way to measure reliability of a test and it refers to the extent that a test produces similar results over time. We calculate the test-retest reliability by using the Pearson Correlation Coefficient, which takes on a value between -1 and 1 where: Test-Retest Reliability (sometimes called retest reliability) measures test consistency — the reliability of a test measured over time. In other words, give the same test twice to the same people at different times to see if the scores are the same.

See also: reliability. Medical Dictionary, © 2009 Farlex and Partners. Essentially, test-retest reliability measures the stability of scores across time. If scores from both administrations are highly correlated with stable scores and error variances across time, then evidence of test-retest reliability is assumed. Pearson's r is used to establish evidence of test-retest reliability. Test-Retest Reliability (sometimes called retest reliability) measures test consistency — the reliability of a test measured over time.

Test–retest is a term used to describe the properties of measure-ment tools evaluated twice on different time occasions. During the last decades, many research reported on the two related but clearly different notions of test–retest, namely, reliability and agreement (e.g. Bland and Altman, 1986; Grenier et al., 2000; Test-retest reliability is the degree to which test scores remain unchanged when measuring a stable individual characteristic on different occasions.
