Violent offenders with schizophrenia : quantitative and qualitative studies focusing on the family of origin
Abstract: The focus of the thesis is on violent offenders with schizophrenia and their relatives. The aims were to explore incidence of violent crimes, the extent to which family members were victims, to investigate individual background factors among violent offenders, and to identify psychotic symptoms and triggering factors associated with fatal violence. In addition, parents were interviewed to build an understanding of their experiences and emotional reactions. One study examined all 369 male individuals who had committed a violent crime (assault, homicide or attempt to any of these crimes), who in a pre-trial forensic psychiatric evaluation (FPE) during 1992-2000 were diagnosed with schizophrenia, and who were referred to forensic psychiatric treatment. Although the majority of the 615 victims was unacquainted to the offenders, family members or male acquainted were most at risk of being severely injured or killed as victims. Background factors were studied for the 207 Swedish offenders who for their first time were subjects of a FPE during the study period. There were indications that those offenders who targeted family members had an earlier onset and more severe course of their mental illness. During the study period, 48 offenders committed homicides. Of the 52 victims, 83% were family members or acquainted to the offender. Those who killed a family member had more often delusions and/or hallucinations, were less often intoxicated, had to a lesser extent committed a previous violent crime and they were younger at the time of the homicide. Parents, who were interviewed, were very emotionally involved in their adult sons, although they were not living together. Ignorance regarding the diagnosis of their son and his criminality negatively influenced the contacts, both between parent and son and between parent and professionals in psychiatry. However, the referral to forensic psychiatric treatment gave the parents hope for a positive development.
