A comparison of the cortisol suppression index and the dexamethasone suppression test in prepubertal children

Results of the dexamethasone suppression test (DST) and the cortisol suppression index (CSI) were compared in 50 depressed prepubertal children and 36 control subjects. The 4:00 p.m. DST, the two-point DST, and the 8:00 a.m. revised criterion CSI yielded the best results and had similar clinical utility and diagnostic confidence values.
