Abstract
During the last decades, interest has increased in structured risk
assessment of future violence as well as in research addressing the link
between schizophrenia and violence. The overall aim of this study was to
extend our knowledge concerning risk assessment and the connection
between schizophrenia and criminal behavior. An additional aim was to
replicate previous studies from North America in a Swedish socio-cultural
context.
Method This study comprised all male violent criminal offenders diagnosed
with schizophrenia (N=272) subjected to a pre-sentence forensic
psychiatric assessment for the first time between 1988 1995.The study had
a retrospective design, where data on background, criminological
characteristics and re-offending were obtained through registers and
files. Predictive validity for various risk factors was estimated with
logistic regression and receiver operating characteristic (ROC) analysis.
Results A psychopathic personality disorder as measured by the
Psychopathy Checklist - Revised (PCL-R) increased the risk for
post-discharge violent re-offending. No other investigated risk factors
yielded the same strong association to violent failure (Paper I). The
historical part of the HCR-20 risk assessment instrument predicted
violent recidivism in a short- (2 years) and a long-term (7 years)
perspective. The Violence Risk Appraisal Guide predicted violent
recidivism in the long- (7 years) but not in the short-term (2 years)
perspective. The predictive accuracy as measured by ROC analysis
increased over time (Papers II & III). Psychopathy was related to
increased violent and non-violent criminality across different age
intervals from adolescence to adult age. Substance abuse did not further
increase crime rates above the level associated with psychopathy (Paper
IV). Offenders with an early onset of criminal behavior differed
significantly from those with a later onset in terms of adolescent
behavior, adult social conditions, criminality and substance abuse (Paper
V).
Conclusions The study suggests that psychopathy and historical risk
factors should be more in focus when assessing risk for future violence
among offenders with schizophrenia. The different trajectories into
criminality suggested by the early/late starter typology might have
implications for treatment.
