Anxiety disorders are among the most common mental health problems in children and adolescents (Ollendick & Pincus, 2008). Epidemiological studies since 1986 have reported that, as a group, anxiety disorders are present in approximately 10% of the population of children ages 6-17 (McLoone, Hudson, & Rapee, 2006). Anxiety disorders have a high prevalence rate, an early onset, significant long-term consequences (Le., school drop-out, psychopathology in adulthood, difficulties with social relationships, lower self-esteem, etc.), and a chronic course if left untreated (Ramirez, Feeney-Kettler, Flores-Torres, Kratochwill, & Morris, 2006). However, youth suffering from anxiety disorders are not always adequately identified and provided with treatment (Neil & Christensen, 2009).
