About the methodology
The Pathocharacterological Diagnostic Questionnaire (PDO) was created by A.E. Lichko and N.Ya. Ivanov at the V.M. Bekhterev Research Institute in the 1970s. The method is based on a clinical-psychological approach to character typology and identifies 11 types of accentuations.
Each type represents an extreme variant of the norm in which certain character traits are excessively strengthened, creating selective vulnerability to specific psychogenic influences while maintaining good resilience to others.
The method has undergone extensive clinical testing and is widely used in Russia and CIS countries for career guidance, counseling, and research purposes.
