[Comorbidity of substance abuse and psychosis. Results of a multicenter study ].

The comorbidity of psychotic disorders and substance misuse disorder (SUD) is a well known and documented phenomenon. The aim of the present study was to find an answer to the question whether among the known Hungarian drug addicts how severe are the occurrence of the psychotic symptoms. The study sample consisted 194 out of 200 clinically treated drug addicts. The instruments used for the investigation were the European Adolescent Assessment Dialogue (Euro ADAD) and the Symptom Checklist 90 Revised (SCL 90-R). The most important findings suggest that the clinically relevant psychotic states were quite rare. The highest values of PSY subscale were associated with dependent people on the "other drugs" (hallucinogens, solvents), cocaine, alcohol and heroin. The correlation between the values of the subscale and the usage of the ambulant or hospital form of mental health care was not too strong, yet significant.
