Romano, PH.D., 1 computer file (PDF); viii, 194 pages, appendices A-H.The main goal of this study was to determine if there are differences in four groups of male adolescents (i.e. child sex offenders, peer/adult sex offenders, crossover sex offenders, and non-sex delinquents) in their levels of psychopathy traits (i.e. grandiosity, impulsivity, lack of empathy, interpersonally exploitative, and risk taking) and antisocial behaviors. The non-sex delinquents group was found to have significantly higher levels of grandiosity and lack of empathy than the three sex offender groups. The three sex offender groups were found to have significantly higher levels of antisocial behavior than the non-sex delinquent group. A confirmatory factor analysis using the Multidimensional Inventory of Development, Sex and Aggression (MIDSA; MIDSA Clinical Manual, 2007) scales for psychopathy traits and institutional record review measures of antisocial behavior provided no evidence for adequate fit for the two, three, or four-latent factor models of psychopathy.en-USAdolescentAntisocialDelinquentPsychopathySex OffenderEducational PsychologyThesis or Dissertation
