One takes clinical and psychopathologic symptoms, which cause ‘circulus vitiosus’ as a criteria of disability. On one hand it is a provocative factor, and on the other it is a consequence of worsening of the psychological condition, which leads to the breach in the society order in one or another area. It is important to determine the medical constituents which limit the vital functions and lead to development of social insufficiency and psychic disorders of patients.

In order to determine the medical criteria which lead to limitations in vital functions and social insufficiency we have examined 460 patients. We found out that the patients having positive syndromes which lead to limitations in vital functions have depression embarrassment, hallucinations, paranoid depression prevail. The negative include asthenic change, reduction of energy potential reduction and regress of a personality. The differentiative diagnostics of clinical and psychopathologic symptoms is not effective under conditions of psychiatric hospital. We found out that the hyperdiagnostics of the criticism level as “absent” and self-appraisal as ‘reduced’ is not proven and needs to be proved experimentally. In its turn, the diagnostics of level of self-appraisal as ‘reduced’ and development of ‘passive’ and ‘supportive’ rehabilitation measures may lead to destruction of the rehabilitation potential of a personality and forms the basis behavior. The examination of the suicidal tendencies should be based on obligatory use of screening methods.
