Test-Retest Reliability - Simple Reliability Testing
Test-retest reliability. The calculation of test-retest reliability is straightforward. The same test is administrated on two occasions to the same individuals under the same conditions. This yields two scores for each person and the correlation between these two sets of scores is the test-retest reliability …

(Gay) Reliability is the degree to which a test consistently measures whatever it measures. Errors of measurement that affect reliability are random errors and errors of measurement that affect validity are systematic or constant errors. Test-retest, equivalent forms and split-half reliability are all determined through correlation.

Test-Retest Reliability. Test-retest reliability was analyzed using data from 39 children who had two Toddler Module administrations within 2 months. Reliability was evaluated using algorithm subtotal scores across the SA and RRB domains, as well as algorithm total scores. Analyses addressing the 12-20/NV21-30 algorithm, which included 31 ...

Reliability. Internal consistency: Analysis of internal consistency yielded a Cronbach’s alpha of .92 for the clinical sample and .93. Test-Retest Reliability: Test-retest reliability was assessed over a one week interval among a sub-sample of 26 outpatients from one clinic site (r = .93). Validity. Content Validity:

Test-retest reliability at a 2-week interval was investigated using n = 30 children aged 4-6 years from Michigan and n = 34 children aged 7-9 years from Texas. Though the correlations shown are acceptable, it would be difficult to generalize about stability over time given the sample characteristics.
