Factor structure of the Hare Psychopathy Checklist: youth version in German female and male detainees and community adolescents.

Substantial evidence exists for 3- and 4-factor models of psychopathy underlying patterns of covariation among the items of the Psychopathy Checklist-Revised (PCL-R) in diverse adult samples. Although initial studies conducted with the Psychopathy Checklist: Youth Version (PCL:YV) indicated reasonable fit for these models in incarcerated male adolescents in the United States and the United Kingdom, only one published study has addressed the factor structure of PCL:YV psychopathy in female adolescents, and no prior studies have addressed it outside of these countries. We used confirmatory factor analysis to investigate the factor structure underlying PCL:YV scores in 314 incarcerated (143 male, 171 female) and 193 in-school (99 male, 94 female) adolescents, ages 14 to 19 years. The 2-factor model provided adequate fit only for incarcerated male adolescents and the 4-factor model was problematic in all samples, but the 3-factor solution provided an adequate model in incarcerated and community male adolescents. None of the models provided consistently acceptable fit among female adolescents. Current findings provide evidence for the robustness of the 3-factor model of psychopathy in incarcerated and community male adolescent samples but raise doubts about the applicability of this model to female adolescents.
