Recent studies estimate that 8-20% of children meet the criteria for an anxiety disorder (Albano et al., 2003; Beidel et al., 1999). If left untreated, anxiety can interfere considerably with social and psychological development (Silverman and Ginsburg, 1998; Mendlowitz et al., 1999). The high prevalence rates and the costs associated with childhood anxiety make investigating risk factors which contribute to the development of anxiety, an important undertaking.
