“…In fact, only one published study to date has investigated the validity and reliability of the PCL:YV in a large sample of adolescent females (N ¼ 125; , and no studies have explicitly compared males and females in terms of how psychopathic features manifest themselves and relate to relevant outcomes. Studies using the PCL:YV with all-male samples have generally supported the concurrent and predictive validity of psychopathic features, by showing, for example, that youth with higher scores on the PCL:YV engage in aggressive and delinquent behaviors more often (Forth & Burke, 1998;Kosson et al, 2002), and tend to recidivate violently, more frequently, and in a shorter period of time compared to low-scoring youth (Catchpole & Gretton, 2003;Corrado et al, 2004;Gretton et al, 2004). Notably, in the latter study by Gretton and colleagues (2004), scores on the PCL:YV (coded from archival information) were shown to contribute to the prediction of violent offending over a 10-year retrospective follow-up period once the effects of prior violence, conduct disorder symptoms, and age at first offense were accounted for.…”
