“…Over the last several decades, research has resulted in substantial progress in the development of effective behavioral and pharmacological treatments for a wide range of childhood disorders (Hibbs & Jensen, 1996;Kazdin & Weisz, 2003;Phelps, Brown, & Power, 2002). Despite such progress, limitations in scientific knowledge and continuing controversies concerning treatment of child and adolescent mental disorders (Leo, 2006) create an imperative to conduct research to establish the efficacy of treatment (Kazdin & Weisz, 2003;Phelps et al, 2002). However, the design and implementation of research concerning psychological and psychopharmacological treatments for children and adolescents with mental disorders raise inherent ethical challenges that need to be addressed (Derivan, Leventhal, March, Wolraich, & Magnozito, 2004;Hoagwood, Jensen, & Fisher, 1996).…”
