Larsson et al. (2006) showed that common genetic influences explained between 43 % and 56 % of the variance in the three
psychopathic dimensions, which is similar to other studies (Blonigen et al. 2003; Taylor et al. 2003).
Our results revealed higher scores for externalizing behavior and
psychopathic dimensions in delinquent males, and higher internalizing problem scores in delinquent females.
We examined 91 male and 123 female adolescent detainees (aged 14 — 19) for psychopathology - using the Youth Self Report, the Overt Aggression Scale - Modified and a Conduct Disorder Self Report Scale - and for

Considering the relevance of the affective
dimension of the
psychopathic personality in developmental and predictive models of youth conduct problems, the Inventory of Callous - Unemotional traits (ICU) has been developed as a reliable and effective measure of callous — unemotional traits (CU) in childhood and adolescence.
Although some studies include the antisocial
dimension as a fourth
dimension, the YPI assesses three
dimensions: grandiose / manipulative (interpersonal), callous / unemotional (affective), and impulsive / irresponsible (behavioral)
psychopathic personality
dimensions (Hare 1991).
It was hypothesized, based on the study of Andershed et al. (2001), that three groups of adolescents with a
psychopathic personality can be distinguished: 1) adolescents scoring low on the manipulative, unemotional, and irresponsible
dimension («relatively normal group»), 2) adolescents scoring moderately on the manipulative and unemotional
dimension and high on the irresponsible
dimension («impulsive, non-
psychopathic-like group»), and 3) adolescents scoring high on all three
dimensions («psychopathy - like group»).
Considering the characteristics of these three subgroups, it seems that one subgroup in our sample scored low on all three
dimensions measuring
psychopathic traits.
Frick et al. (1999) stated that utilizing different measures or different concepts of a
psychopathic personality (a single
dimension versus separate
dimensions) to test the relationships could explain the mixed findings in the literature.
