[Scales of the "O" symptom questionnaire].

The article presents the scales of the "O" Symptom Check-list which were derived on the basis of an analysis of a patient population of over three thousand. The patients filled out the "O" Symptom Check-list before treatment. 14 variables of various syndromes were constructed, which corresponded with most of the neurotic disorders classified in ICD-10. The results obtained were compared with the scales constructed 20 years ago, in an attempt to explain the dynamics of the psychopathology in the course of those years. It was noted that the analysis of the results of the single scales can be helpful in defining and observing the most common neurotic disorders and noting their comorbidity.
