  1. Areas under Receiver Operating Characteristics Curves using the three different A-TAC scales (DSM-IV items, Gate items and Sum scores) as predictors of the diagnoses specified in the second column using first the clinical sample and controls, and then both the clinical and the community samples and the controls (data for both sexes is given in this Table, while data for boys only are given in Table 2 and for girls only in Table 3).
