Empirically derived MMPI profile subgroups of incarcerated homicide offenders.

Several classification systems have been developed to identify subgroups of criminals. Recently, investigations have attempted to derive empirical classifications of specific types of offenders. The present study investigated the occurrence of MMPI profile subgroups in a sample of incarcerated homicide offenders. One hundred and eighteen convicted male homicide offenders were the subjects. MMPIs were collected as a part of evaluations to determine eligibility for a work release program. Results identified four distinct profile subgroups, which ranged in levels of psychopathology from normal to severely disturbed. Subgroups are discussed with reference to previous research and the development of a taxonomic system for homicide offenders.
