Note: Equivalence Intervals (EI) are based on adjusted cell means for the pure GAD group. Superscripts denote non-equivalence. GAD CSR= GAD Clinical Severity Rating on the Anxiety Disorders Interview Schedule for DSM-IV: Child and Parent version; C-GAS=Children’s Global Assessment Scale; CASAFS=Child and Adolescent Social and Adaptive Functioning Scale.
