Homicide, Psychopathy, and Aging-A Nationwide Register-based Case-comparison Study of Homicide Offenders Aged 60 Years or Older

With populations aging there have been some concerns on elderly offending. We compared elderly homicide offenders with a younger comparison group with special emphasis on psychopathy. We analyzed nationwide register-based material on all homicide offenders aged 60 or older who were in a forensic psychiatric examination in Finland 1995-2004 and their gender-matched comparison group of younger homicide offenders. The offenders 60 years or older were diagnosed less often than the younger ones with drug dependence and personality disorders and more often with dementia and physical illnesses. The mean Psychopathy Checklist-Revised total scores as well as factor and facet scores were lower in the 60 or older age group. The group 60 years or older had significantly lower scores on eight individual items of social deviance. The interpersonal/affective factor 1 scores did not differ. Understanding the possible underlying phenomena of violent behavior may provide help for developing services for the elderly. Language: en
