in child mental health services, the term parent training (Pt) refers to an evidence-based treatment for children with disruptive behavior. the efficacy of Pt in treating disruptive behavior in children with oppositional defiant disorder and attention-deficit/hyperactivity disorder from preschool to adolescence is supported by decades of research (dretzke et al., 2009;Michelson, davenport, dretzke, Barlow, & day, 2013). indeed, clinicians can choose from one of several well-established, structured programs, including Webster-stratton's (n.d.) incredible years, Kazdin's (2005) Pt, Barkley's (2013) defiant children, and eyberg's Parent-child interaction therapy (Mcneil & Hembree-Kigin, 2011). this body of evidence has influenced international dissemination of Pt and has prompted several clinical practice guidelines in the united states, united Kingdom, and elsewhere in an effort to raise standards of mental health care for youths (american academy of child and adolescent Psychiatry, 2007; national institute for Health and care excellence, 2006).
