Who are you?

Personality Testing

The PST-R ® Personality Structure Assessment 
Who am I?  Why do I do the things I do?

The PST-R ® Personality Structure Assessment is a scientifically evaluated diagnostic tool which offers a reliable insight into the various characteristics and structure of the personality. It was developed by German psychologist Dr. Michael Dieterich and is continually being developed further by the Institute of Practical Psychology.


What makes the PST-R ® so unique?

A unique element of the PST-R ® is its ability to identify differentiated layers of the personality.  The PST-R ® assumes that while personality is partially inherited, a significant portion is formed over the course of a lifespan. The PST-R breaks the personality down according to the following three layers:


  • The earliest acquired deep core structure

  • The basic structure formed in early life 

  • The most recent perceivable and changeable outward character traits


By measuring the three layers, it is possible to recognize which areas of the personality are well embedded and unlikely to change; and in which areas the potential for change and growth still exist.


Based on these findings, a holistic approach is utilized to develop and implement an individualized treatment plan or self-development program, which is encouraged and supported through individual counseling or  group counseling.


The PST-R ® incorporates the concepts of the 16 Personality Factor Tests (16 PF) according to Schneewind, the Eysenck Personality Inventory (EPI), the Freiburg Personality Inventory (FPI), and the depth psychology approach of Fritz Riemann, Eric Berne, Alfred Adler, etc..

The instrument consists of 324 multiple-choice questions which take approx. 60 - 90 minutes to answer, and is available in the English, German and French languages.
