Background Information for the STAB Model
The STAB model is not a procedure that can be assessed with the common quality criteria of personality-related psychological testing procedures. It concerns an explanatory model which allows the target group members from management (who have no relevant experience in this context) to examine their own everyday differential models for the description of human behaviour, particularly in work situations. In the process they review concepts based on well-ordered decision-making. In this regard, a linguistic differentiation of behaviour is used which was already developed by William Marston in 1928 in his book “The Emotions of Normal People” on the basis of Jungian type formation.
(Marston’s book was reprinted in 1989 as “one of the 100 most important specialized psychological books of the 20th century”, firstly by Thomas Lyster Publishing, Ormskirk England; since 1999, it has been published by Routledge London – New York)
The STAB model utilised by Process One is one of the various existing instrumented adaptations of the original Marstonian differential model which have been developed under the term “Disc” over the course of decades.
This adaptation was developed at the end of the 80s and has been applied in various didactic work contexts. However, we consider its utilisation as a diagnostic tool to be inappropriate and exaggerated.
The apparent validity of the model in a didactic context is very high (overall, several thousand people). The content-related validity is based upon item analysis which has been carefully implemented in the design with the assistance of multi-person ratings from linguistic experts. In an English version of the DISC model, there is both a reliability test as well as correlation analysis with the 16 PF type indicator which shows validity at the level of 1%.
