“…Family aggregate studies indicate that children of anxious parents have an elevated rate of anxiety disorders (Beidel & Turner, 1997;Biederman et al, 1996;Merikangas et al, 1998;Petty et al, 2008;Turner, Beidel, & Costello, 1987) and parents of children with anxiety disorders experience higher rates of anxiety disorders (Last, Hersen, Kazdin, Francis, & Grubb, 1987;Last, Hersen, Kazdin, Orvashel, & Perrin, 1991). A recent modelling study investigating risk factors for childhood anxiety found that anxious rearing significantly predicted symptoms of anxiety disorders at 1 year follow-up and trait anxiety of both parents at 1 year follow-up made independent contributions to child anxiety symptoms at 2-year follow-up (Muris et al, 2011).…”
