Construct and predictive validity of the Psychopathy Checklist: screening version in a violent offender population in Australia

The base rate of psychopathy is consistently reported to be considerably higher in offender populations compared to in the general community. A debate in the research literature concerning psychopathy assessment surrounds the role of antisocial behaviour within the conceptualisation of the Psychopathy Checklist instruments. This thesis is the first comprehensive evaluation of the screening version of the Psychopathy Checklist in an Australian offender sample. Results failed to support the established conceptualisation of this tool; yet results were consistent with international research for predicting reoffending. Findings have implications for the risk assessment, treatment, and management of Australian violent offenders.
