Eighteen bereaved children and adolescents were assessed using the dexamethasone suppression test (DST) and the Diagnostic Interview for Children and Adolescents 4 weeks following parental death. Thirty-nine percent had a positive (nonsuppressed) DST. DST-positive subjects reported more DSM-III-R depressive symptoms (6.3 +/- 2.9 vs. 3.9 +/- 2.7, means +/- SD) than DST-negative subjects. Most frequently reported symptoms included dysphoria, loss of interest, sleep disturbance, appetite disturbance, psychomotor disturbance, and morbid and suicidal ideation. Post-dexamethasone cortisol levels were significantly correlated with the total number of depressive symptoms and suicidal ideation.

Sensitivity, specificity, and diagnostic confidence of the Children's Depression Inventory (CDI) and the dexamethasone suppression test (DST) in assessing childhood depression were determined. Parent and child forms of the CDI and plasma cortisol levels at 8 a.m. and 4 p.m. were used. Three groups of prepubertal children were sampled: (1) 63 depressed inpatients, (2) 14 non-depressed inpatient psychiatric controls, and (3) 21 normal community sample controls. Results suggest that scores greater than or equal to 15 on the CDI obtained from either parent or child provide a good screening instrument (sensitivity = 89%). If the DST is administered to all children with elevated CDI scores, diagnostic confidence is 97.5%. Cautions and recommendations for use of the CDI and DST are made.

Hospitalized prepubertal depressed children with abnormal dexamethasone suppression test (DST) results were treated and given repeat DSTs at 6 weeks (N = 21) and 5 months (N = 14). DST results were significantly correlated with clinical status at 5 months but not at 6 weeks.

Cholesterol, sodium, potassium, and serum glucose were examined to determine if they could predict status on the dexamethasone suppression test (DST) in 59 depressed prepubertal psychiatric inpatients and 21 nondepressed psychiatric inpatients. Multivariate analyses found that none of these variables, alone or combined, were predictive of DST results.

The dexamethasone suppression test was performed on 20 hospitalized prepubertal children who met DSM-III criteria for major depressive disorder. Fourteen children (70%) did not suppress cortisol secretion at either 8:00 a.m. or 4:00 p.m. The 4:00 p.m. value alone predicted 93% of the nonsuppressors.

The dexamethasone suppression test (DST) was performed in 50 hospitalized prepubertal children who met DSM-III criteria for major depressive episode, 18 hospitalized controls with a psychiatric disorder, and 18 nonhospitalized normal controls. Baseline and post-DST cortisol levels were measured at 8 a.m. and 4 p.m. The depressed children had consistently higher cortisol levels than the controls at baseline and post-DST. The DST was positive in 82% of depressed children, 28% of psychiatric controls, and 11% of normal controls. The results indicate that prepubertal depressed children may have abnormalities in the hypothalamic-pituitary-adrenal axis similar to those in adults with a major depressive illness.

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.
