La. Marshall et Dj. Cooke, The childhood experiences of psychopaths: A retrospective study of familial and societal factors, J PERS DIS, 13(3), 1999, pp. 211-225
We compared the childhood experiences of criminal psychopaths with those of
criminal nonpsychopaths, to examine whether differences in either the type
or intensity of adverse experience in childhood could be identified. One h
undred and five prisoners, 50 psychopaths, and 55 nonpsychopaths were asses
sed with the Psychopathy Checklist-Revised (PCL-R) and Childhood Experience
of Care and Abuse (CECA) semistructured interviews, Both assessment measur
es have been demonstrated to be reliable and valid instruments, File inform
ation from both adult and child services provided corroborative material. F
actor analysis of the childhood experience variables revealed two distinct
factors, familial and societal, both of which were highly correlated with a
dult psychopathy scores. These findings suggest that: the experiences psych
opaths have in childhood influence adult outcome.
