Abstract

Preliminary evidence shows that personality traits are important in determining violent behavior in schizophrenia. As only some patients with schizophrenia show a greater risk for violence, this risk may therefore be considered as dynamic, varying as a function of the extent to which certain personality dimensions are present and the degree to which environmental events moderate or exacerbate their expression.

OBJECTIVE:

To compare temperament and character dimensions between violent and non-violent schizophrenic patients and to determine which temperament and character dimensions are predictors of violent behavior in schizophrenia.

METHOD:

We recruited 102 schizophrenic patients without concomitant substance abuse 4 months prior to the assessment. Diagnoses were based on the SCID-I. Personality dimensions were assessed with the Temperament and Character Inventory and violent behaviors with the Overt Aggression Scale.

RESULTS:

Higher levels of the temperament dimension novelty seeking and a lower cooperativeness, as a character dimension, were risk factors for violent behavior in schizophrenic patients.

DISCUSSION:

Our data indicate that schizophrenic patients will show a greater risk for violence according to certain personality configurations and the degree to which environmental events moderate or exacerbate their expression.
