Psychopathic personality traits and delinquent and risky sexual behaviors in Croatian sample of non-referred boys and girls.

The current study investigated the association of psychopathic traits with violent and non-violent delinquency, delinquency versatility, and risky sexual behavior in Croatian sample of non-referred boys (n = 226) and girls (n = 480). Psychopathic traits were measured by the self-report Youth Psychopathic Traits Inventory (YPI). Consistent with the study's hypotheses, Impulsive-Irresponsible and Callous-Unemotional dimensions were most consistently associated with all outcome measures. Results of the regression analyses showed that the Impulsive-Irresponsible behavioral style had stronger association with non-violent delinquency and delinquency versatility for boys. However, the Impulsive-Irresponsible dimension had stronger influence on risky sexual behavior for girls compared with boys. The results of a two-group confirmatory factor analysis revealed that the three-factor model of the YPI was invariant across gender.
