Disruptive behavior disorders in children are distressing to others due to the abnormal nature of the child's behavior (Christophersen & Mortweet, 2003). These disorders include attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). Prevalent rates for these disorders range from 2% to 23% of the population. A commonly identified contributor to the exacerbation of symptoms is parenting, specifically a coercive parenting style (Patterson, 1982). Several parent training programs have been developed and found to be effective in reducing child and adolescent problem behaviors (Barlow & Cohen, 2004; Bunting, 2004). The current dissertation represents an adaptation of one of these programs, Webster-Stratton's (2008), "Incredible Years" program, to Appalachian culture. An underserved ethnic minority, Appalachians, are identified in the literature as characterized by personalism (Jones, 1994), familism (Keefe, 1986), high-context communication (Puckett, 2005), and adult-centered parenting (Cole, 1988). Webster-Stratton's program is well researched and empirically validated to reduce problem behaviors in conduct disordered children and has been found to be effective in many cultures (Gross, Fogg, Webster-Stratton, Garvey & Grady, 2003). The current project entails both a detailed description of program components, and a description of a method for systematically evaluating program effectiveness.
