The association between the personality disorder we now
term psychopathy and criminal behaviour has long been recognised.
For example, in the book of Psalms the traits of pride, vanity, and
manipulativeness were linked with extreme violence. Empirical research
over the last two decades has suggested that psychopathy is linked
to risk of reoffending in general, and violent reoffending in particular.
The validity of this view will be examined: It will be argued that
it is necessary to move towards a greater understanding of the mechanisms
by which these traits may be criminogenic, i.e., drive individuals
to offend. The limitations of current measures of the disorder will
be described. Proposals for the development of improved measures
will be discussed based on the analyse of large data sets. It will
be argued that there is a need for a comprehensive, clinically informed,
measure of psychopathy. Preliminary results from a programme attempting
to develop such a measure will be described.
