Characteristic hostility in schizophrenic outpatients

Abstract

In this study of 133 schizophrenic outpatients, we assessed characteristic hostility and correlates of hostility over a 6-month period. Results showed that 13 percent of the study group were characteristically violent, 18 percent were characteristically threatening, and another 21 percent were irritable and argumentative. About half (48%) were without hostility. A multiple regression model identified six variables-housing instability, hallucinations or delusions, schizoaffective diagnosis, lack of depression, alcohol use, and bizarre behavior-that together accounted for over 50 percent of the variance in observed characteristic hostility. Hostility also predicted rehospitalization and total inpatient days during 1-year followup. Implications of these findings for assessment and future research are discussed. © 1991 Oxford University Press.
