Validitiy and Realiabilty

SIZE PROZESS® electronic online questionnaires

For the SIZE PROZESS® Personality Anlyses, scientifically evaluated online questionnaires are being used exclusively.


The SIZE PROZESS® personality questionnaires were evaluated and further developed in cooperation with Univ. Prof. Dr. Thomas Werani (JKU Linz), so that the scientifically defined requirements for the quality criteria of reliability and validity are being met.

 "The overall quality of the SIZE PROZESS® measuring instrument is high!



All scales which the SIZE PROZESS® measuring instrument is based on, meet the defined minimum requirements for the proof of reliability and validity, with most scales far exceeding these. The overall quality of the SIZE PROZESS® measuring instrument can therefore be classified as high.

This result is statistically well backed up (secured).  This is because a) not only first generation methods were used for the scale test, but also second-generation methods, which are considered to be more demanding, and b) the test is based on a broad database (n = 751)".
