Only children with scores one standard deviation above or below the normative mean on the Approach scale were invited to participate in the study and were classified as behaviourally inhibited (BI, n 1⁄4 85) or behaviourally uninhibited (BUI, n1⁄479). Of the BI children, 69 met criteria for an anxiety disorder (AD), using the ADIS-P-IV (see below) and five BUI chil- dren also met criteria for an anxiety disorder. These 74 children (45.1%; 41 girls and 33 boys) were included in the AD group. The remaining 90 children (54.9%; 51 girls and 39 boys) who did not meet criteria for an anxiety disorder were included in the Non-AD group.
