The SIZE PROZESS® personality model offers a grounded and systematic way of looking at personality, which is also taken into account within theoretical measurement criteria. One key advantage is the complex scaling which foregoes simple overall scores and instead focuses on the individual combination of sub-results in order to present the complexity of the personality. This enables you to obtain detailed insights into your self-concept and that of others, as well as your overall personality, based on six personality traits.

The questionnaire uses a tried and tested 5-layer answer scale in a forced-choice format, which has proven itself as robust against falsification attempts. The reliability and construct validity have been tested using classical (explorative factor analysis, Cronbach's alpha) and modern (confirmatory factor analysis (SEM)) procedures. The results show exceedingly satisfying values in terms of the tested quality criteria and confirm the underlying theoretical model.

In summary, the SIZE PROZESS® questionnaire meets the current statistical standards for psychological measurement tools and can be considered extremely valid and reliable.
