“…In regard to internal consistency, alpha coefficients range from .79 to .94 for total scores (Forth et al, 2003;Vitacco et al, 2010) and alphas for factor scores range from .50 to .82 (Andershed, Hodgins, & Tengstrom, 2007;Forth et al, 2003;Vitacco et al, 2010;Vitacco, Neumann, Caldwell, Leistico, & van Rybroek, 2006). Intraclass correlation coefficients range from .82 to .98 (Andershed et al, 2007;Cauffman et al, 2009;Das et al, 2009;Forth et al, 2003). PCL:YV scores are also correlated with externalizing psychopathology, violence, antisocial behaviour, and recidivism (Kosson et al, 2002;Kubak & Salekin, 2009;Murrie et al, 2004;Salekin, 2008;Salekin et al, 2004;Schmidt et al, 2006;Vitacco et al, 2006;2010).…”
