Reliability and validity

Tried and tested

Professor Dr Steven Reiss was an experienced test theoretician. The Reiss Profile shows very good validity scores. 

Quality criteria

Each test must fulfil three basic requirements:

  1. Objectivity, meaning that all qualified persons must be able to carry out and then interpret the test results by applying the same criteria.
  2. Validity, meaning that the test should measure what is supposed to be measured.
  3. 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.
