Test-retest reliability refers to the consistency of a test's results when the same individuals take the test multiple times under similar conditions. If a test has poor test-retest reliability, it means that the scores are not consistent across testing sessions, which makes it unsuitable for repeated measures designs (A), indicates that participants may receive different scores on successive occasions (B), and implies that the reasons for score changes cannot be easily determined because the inconsistency could be due to the test's unreliability rather than actual changes in the trait being measured (C).
