features identified by Soviet psychiatrists P. B. Gannushkin and O. V. Kerbikov, which are characteristic of personality disorders (“constitutional psychopathies” according to P. B. Gannushkin). These criteria include:
1) Totality (pathological traits manifest themselves everywhere: at home, in society, at work, in everyday conditions and under emotional stress; in turn, a pathological trait determines the entire mental image of a person);
2) Stability (pathological traits persist throughout life, little reversible);
3) Violation of social adaptation / social disadaptation (pathological characteristics of the personality are expressed to a degree that prevents successful social adaptation; in this case, social disadaptation is a consequence of pathological traits and is not due to an unfavorable environment).
