Temperament and character differences in psychopathic and non-psychopathic antisocial adolescents

Abstract

The present study tested the possibility of distinguishing between different types of antisocial adolescents based on psychopathic characteristics, and the differences between antisocial adolescents of different ages and subtypes in relation to the Cloninger's personality dimension. The sample included 101 antisocial male adolescents, divided into two age groups (71 respondents in the 13-17 age group and 30 in the 18-25 age group). After conducting model-based cluster analyses, non-psychopathic type (without pronounced signs of psychopathy) and psychopathic type (with pronounced antisocial, lifestyle and interpersonal facet) (Hare’s model) were singled out in the whole sample. Within the psychopathic type, in comparison with juveniles, older adolescents showed a significantly lower expression of character dimensions of Self-directedness and Cooperativeness, which are key in determining all personality disorders. Within the group of juvenile offenders, members of the two subtypes did not differ significantly in temperament and character, which indicates that juveniles are in the process of personality development, especially when it comes to their character, so they are more susceptible to treatment and their outcomes are uncertain. The results suggest that the inflation of psychopathic scores may occur in juveniles due to the identification of developmental features of adolescence (impulsivity, immaturity) as psychopathic, which implies the need to apply basic personality models in the assessment of antisocial adolescent.
