Objectives：Violence is a serious problem in some patients with schizophrenia. Homicide is one of the most extreme aggressive behavior. The purpose of this study was to investigate the characteristics of subjective symptomatology and psychological state of schizophrenia with homicidal behavior.
Methods：Subjects were schizophrenia patients hospitalized in a mental hospital due to their homicidal behavior (n=64, group 1). Control subjects were schizophrenia patients without homicide also hospitalized in another mental hospital(n=75, group 2). Subjects were matched by age, years of education and dosage of antipsychotics. Minnesota Multiphasic Personality Inventory(MMPI) and Symptom checklist-90-R(SCL-90-R) were used to evaluate the subjective symptomatology. In group 1, the results of MMPI and SCL-90-R had been acquired following the incident that led to hospitalization.
Results：Schizophrenia patients with homicide showed overall elevated MMPI clinical scales and SCL-90-R scales. The group with homicidal behavior had significantly higher scores than patients without homicidal behavior on the subscales of depression, hysteria, psychopathic deviance, paranoid, social introversion as assessed by the MMPI. They also had significantly higher scores on the subscales of obsessive-compulsive, interpersonal sensitivity, anxiety, paranoid ideation, psychoticism as assessed by the SCL-90-R.
Conclusion：Schizophrenia patients with homicidal behavior did present different clinical subjective pictures : unstable emotion, more paranoid tendency, difficulty with control of anger, more perceptual disturbance. Under those subjective states they had a risk of violent behavior.
