There were 511 men with schizophrenia who performed socially dangerous acts. All patients were further divided into 2 groups of comparison: group І — persons with a negative personality mechanism of implementation (127 persons) and group ІІ — persons with a productive-psychotic mechanism for the implementation of socially dangerous acts (251 persons). In order to achieve the goal, a comprehensive approach was used including clinicopsychopathological and statistical methods. As a result of a study of patients with schizophrenia who committed the SDA against human life, the existence of violations of their social and labor adaptation has been confi rmed. According to the structure of socio-demographic factors characterizing social disadvantages and contributing to the manifestations of social danger, this contingent practically does not diff er from the general population of persons, on which the court applied other types of compulsory measures of a medical nature. As a result of the analysis, there was confi rmed the existence of violations of social and labor adaptation of schizophrenic patients who committed socially dangerous acts. It has been proved that the mechanism of realization of a socially dangerous act can be considered as an important predictor of the repeated SDA.
