Test-retest reliability is being assessed because the same measure is being administered to the same respondents at two separate times to determine if the results are consistent over time. Split-half reliability involves splitting a measure into two halves and comparing the scores, equivalent-forms reliability involves administering two parallel forms of a measure, and criterion validity involves comparing the results of a measure to an external standard to determine its accuracy.
