Reliability and validity
Tried and tested
Professor Dr Steven Reiss was an experienced test theoretician. The Reiss Profile shows very good validity scores.
Each test must fulfil three basic requirements:
- Objectivity, meaning that all qualified persons must be able to carry out and then interpret the test results by applying the same criteria.
- Validity, meaning that the test should measure what is supposed to be measured.
- Reliability, meaning that it should be reliable in terms of implementation and results.
The Reiss Profile® fulfils the following scientific criteria
- Test-Retest-Reliability: the four-week Test-Retest-Reliability of the 16 scales scores between 0.69 and 0.88, internal consistency – measured using Cronbachs Alpha – between 0.71 and 0.92.
- Validity: the 16 scales show high levels of concurrent and criterion-related validity. Several scales also show high convergence validity.
- Objectivity: the test manager independent online test guarantees objectivity when taking the test.
- Social desirability: social desirability – checked using Marlowe-Crowne Social Desirability Scale (MCSDS) – is under three percent.
