Abstract

BackgroundIn his developmental model of emerging psychopathy, Lynam proposed that the -fledgling psychopath- is most likely to be located within a subgroup of children elevated in both hyperactivity-inattention-impulsivity HIA and conduct problems CP. This approach has garnered some empirical support. However, the extent to which Lynam-s model captures children who resemble psychopathy with regard to the core affective and interpersonal features remains unclear.

MethodsIn the present study, we investigated this issue within a large community sample of youth N = 617. Four groups non-HIA-CP, HIA-only, CP-only, and HIA-CP, defined on the basis of teacher reports of the Strengths and Difficulties Questionnaire SDQ, were compared with respect to parent-reported psychopathic-like traits and subjective emotional reactivity in response to unpleasant, emotionally-laden pictures from the International Affective Pictures System IAPS.

ResultsResults did not support Lynam-s model. HIA-CP children did not appear most psychopathic-like on dimensions of callous-unemotional and narcissistic personality, nor did they report reduced emotional reactivity to the IAPS relative to the other children. Post-hoc regression analyses revealed a significant moderation such that elevated HIA weakened the association between CP and emotional underarousal.

ConclusionsImplications of these findings with regard to the development of psychopathy are discussed.
