Anxiety disorders are the most prevalent class of psychiatric disorders (Kessler, et al., 2005) and their early onset places individuals at risk for a wide range of subsequent problems (Weissman, et al., 1999). Data from the National Latino and Asian American Study (NLAAS) and the National Comorbidity Survey-Replication (NCS-R) were used to investigate the prevalence and correlates of childhood-onset anxiety disorders among U.S.-born whites, U.S.-born Latinos, and foreign-born Latinos. Significant differences in rates of childhood-onset anxiety disorders were found, with foreign-born Latinos reporting the lowest rates. Across all three ethnicity/nativity groups, individuals with childhood-onset anxiety disorders had equal or higher levels of past-year impairment, relative to individuals with adult-onset anxiety disorders. The chronic course associated with childhood-onset anxiety disorders was also revealed to be present regardless of ethnicity and nativity, as indicated by the similarities across groups in the mean number of lifetime disorders and comorbidity rates. Treatment and assessment recommendations are discussed with respect to the findings.

Separation Anxiety Disorder (SAD) is the most commonly diagnosed and impairing childhood anxiety disorder, accounting for approximately 50% of the referrals for mental health treatment of anxiety disorders. While considered a normative phenomenon in early childhood, SAD has the potential to negatively impact a child's social and emotional functioning when it leads to avoidance of certain places, activities and experiences that are necessary for healthy development. Amongst those with severe symptoms, SAD may result in school refusal and a disruption in educational attainment. This paper provides a comprehensive review of the current literature on SAD etiology, assessment strategies, and empirically supported treatment approaches. New and innovative approaches to the treatment of SAD that also employ empirically supported techniques are highlighted. In addition, future directions and challenges in the assessment and treatment of SAD are addressed.
