Children and adolescents with Conduct Disorder (CD) engage in persistent and repetitive behaviors that violate the rights of others (e.g., fighting, bullying, theft) or basic social rules (e.g., running away from home, being truant form school). The worldwide prevalence of CD is approximately 50 million, and CD is currently estimated to account for 5.75 million years lived with disability globally (Erskine et al., 2014; Whiteford et al., 2013). Children with CD are at increased risk for a wide range of physical, mental, and social problems as adults (Colman et al., 2009), and this is especially true for children who exhibit an early-onset and persistent pattern of conduct-problem symptoms (Colman et al., 2009; Moffitt, Caspi, Harrington, & Milne, 2002; Odgers et al., 2008; Piquero, Daigle, Gibson, Piquero, & Tibbetts, 2007; Piquero, Shepherd, Shepherd, & Farrington, 2011).
