The dexamethasone suppression test in depressed retarded adults: preliminary findings.

This study was undertaken to determine the utility of the Dexamethasone Suppression Test (DST) for diagnosing depression in institutionalized mentally retarded persons. Depressed and nondepressed institutionalized mentally retarded persons were given 1 mg dexamethasone for an overnight DST. Serum cortisol concentrations greater than 4 micrograms/dl at both 8:00 AM and 4:00 PM provided discrimination of depressed from nondepressed groups. Also, using the criteria of serum cortisol concentrations greater than 4 micrograms/dl at 8:00 AM and 4:00 PM, at 4:00 PM and 10:00 PM, or at 8:00 AM, 4:00 PM, and 10:00 PM differentiated these groups. These results suggest that the DST may be useful for detecting melancholia among institutionalized retarded persons.

Concurrent validity of the behavior development survey.

The Vineland Social Maturity Scale, the Peabody Picture Vocabulary Test (PPVT), the Adaptive Behavior Scale (ABS), and the Behavior Development Survey, an abbreviated five-domain version of the ABS, were administered to a stratified random sample of 111 mentally retarded individuals. The network of correlations obtained among these measures indicated that the Behavior Development Survey is a concurrently valid method of assessing adaptive behavior and demonstrates a pattern of correlations with the Vineland and the PPVT similar to that demonstrated by the more extensive ABS.
