The longitudinal course of anxiety disorders in 45 children and adolescents with Williams syndrome (WS) was examined. Children were ages 4–13 years at the initial assessment. To assess their child’s DSM-IV diagnoses, parents completed a structured diagnostic interview 3–9 times at intervals of at least 1 year.
