Revisiting the association of aggression and suicidal behavior in schizophrenic inpatients.
ABSTRACT Our study investigated the association of aggression and suicidal behavior in schizophrenic inpatients. Eight thousand nine hundred one admissions for schizophrenia (1998-2007) to a psychiatric university hospital were included. Schizophrenic suicides (n = 7)/suicide attempters (n = 40) were compared to suicides (n = 30)/suicide attempters (n = 186) with other diagnoses and to schizophrenic non-attempters regarding aggression. Logistic regression analysis was performed to explore risk factors for attempted suicide. Schizophrenic suicides/suicide attempters did not differ from other suicides/suicide attempters or from schizophrenic non-attempters with regard to aggression. Risk of inpatient suicide attempt was increased for patients with attempted suicide at admission, high school graduation, and disorganized subtype. Aggression could not be found to be a predictor of attempted suicide. Aggression seems to have a minor role for suicidal behavior in schizophrenia.

ABSTRACT: In the research literature, aggressive behavior has traditionally been classified into two distinct subtypes, impulsive or premeditated. Impulsive aggression is defined as a hair-trigger aggressive response to provocation with loss of behavioral control. Premeditated aggression is defined as a planned or conscious aggressive act, not spontaneous or related to an agitated state. The present study outlines the development of a clinically useful self-report instrument, the Impulsive/Premeditated Aggression Scales (IPAS), designed to characterize aggressive behavior as predominately impulsive or predominately premeditated in nature. The IPAS showed strong reliability and validity. Analysis of the IPASscores demonstrated thepresence of two types of aggressive behavior, impulsive and premeditated, in men referred for anger problems. The aggression of most individuals in the present sample was characterized as predominately impulsive in nature (90%).Assessment 07/2003; 10(2):183-90. · 2.01 Impact Factor
