1. Test-retest reliability was also adequate. 2. PPA consistently shows test / retest reliability . 3. In doing this, each scale forms a unidimensional construct, demonstrating good test-retest reliability . 4. Additionally, there was strong test-retest reliability in K-D tests in both groups. 5. The test-retest reliability of the NEO PI-R has also been found to be satisfactory. 6. They reported a favorable analysis in terms of internal consistency, test-retest reliability , and concurrent validity. 7. High test-retest reliability is good, because it proves that the data collected from the study is consistent. 8. Reliability has been assessed by numerous independent researchers and it has clearly demonstrable internal consistency and test-retest reliability . 9. The MSQoL was assessed for reliability and validity and was found to have good consistency and test-retest reliability . 10. Retest reliabilities of the global scales ranged from 0.72 to 0.94 where retest stability increasing with age.
