“…The migration of the concept to children has shown many similar findings, with raters evidencing independent agreement, and measures demonstrating structural stability and concurrent and predictive meaning (see Salekin, 2006;Salekin, Rosenbaum, & Lee, 2009a) as well as a genetic basis (Larsson, Andershed, & Lichtenstein, 2006;Viding & Larsson, 2010). Several research findings have shown, however, that there may be some developmental differences in the concept of psychopathy in childhood, in that studies tend to indicate only modest levels of stability, greater levels of comorbidity (Kubak & Salekin, 2009;Salekin, Leistico, Trobst, Schrum, & Lochman, 2005;Salekin, Neumann, Leistico, DiCicco, & Duros, 2004b), and dissimilar correlates with internalizing symptoms and some performance tasks (see Forth, Kosson, & Hare, 2003;Lee, Salekin, & Iselin, 2010;Salekin, 2006;Salekin & Frick, 2005;Salekin, Rosenbaum, Lee, & Lester, 2009).…”
