摘要

Considerable evidence suggests that violent behavior observed in schizophrenic patients is motivated by psychotic symptomatology. The understanding of violence in schizophrenic patients requires consideration of psychiatric symptomatology. Objective: This study investigated the relationship between violent behavior and psychiatric symptomatology in schizophrenic patients. Method: One hundred and thirteen patients were recruited. Thirteen patients were excluded due to concomitant substance abuse six months prior to the assessment. Diagnoses were based on the SCID-1. Psychotic symptom severity was assessed with the PANSS. Violent behaviors were assessed with the OAS. Results: Violent behaviors were associated with more severe psychotic symptomatology including hallucinations, delusions, excitement, poor impulse control, and thinking disturbances. Conclusions: Patients with exacerbation of psychotic symptomatology have an increased risk of violent behavior. It is necessary to determine which subtypes of hallucinations and delusions are implicated in the association of schizophrenia and violent behavior. Violent behavior in schizophrenic patients is a heterogeneous phenomenon best explained in the context of specific symptoms associated with violence and course of illness. The retrospective assessment of the variables raises methodological questions concerning the reliability of measurement of the impact of psychotic symptoms on violence. Aggr. Behav. 31:511-520, 2005.
