The purpose of this research study is to see how certain hormones cause changes in mood and thinking in some depressed patients and to determine the effectiveness of mifepristone in treating some forms of depression.
This study is conducted in conjunction with an observational study "Clinical and Biological Characteristics of Psychotic Depression".

- Change in Psychotic Symptoms Subscale (PSS) of the Brief Psychiatric Rating Scale (BPRS) [ Time Frame: baseline to day 9 ]
The BRPS is a rating scale of various psychiatric symptoms. Each item is rated on a scale of 1 to 7, with 1 being not present. The PSS is the sum of 4 items from the BPRS, which indicates the level of positive psychotic symptoms.. Thus, the range for the PSS is 4 to 28, with higher scores indicating greater levels of positive psychotic symptoms.
For ease of interpretation, the sum of the PSS then has 4 items subtracted so that a score of 0 (instead of 4) indicates that there are no psychotic symptoms. In doing this, the range for the PSS becomes 0 to 24), with larger values indicating more positive psychotic symptoms.
The measure is the change score of PSS total day 1 less PSS total Day 9. 0 indicates no change, where as positive numbers indicate a decrease in psychotic symptoms.
- Change in Mean Cortisol Level [ Time Frame: Day 1 to Day 9 difference ]The reported value is the difference in mean evening cortisol from baseline to Day 9 The mean evening cortisol is calculated from the hourly cortisol value taken from 1800 hrs to 0100 hrs for both time points. The outcome measure is the difference of mean evening cortisol from Day 9 less the mean evening cortrisol from baseline. Negative values indicate a reduction in cortisol levels at Day 9, whereas positive values indicate an increase in cortisol at Day 9. Serum cortisol levels are reported in ug/dL
- % Change in Mean Evening Pre- and Post- Florinef Cortisol After Treatment With Either Mifepristone or Placebo [ Time Frame: Day 23 ]
Time 1 (baseline) = Difference in cortisol level from Day 1 (pre-florinef mean evening cortisol) at Baseline less Day 2 (post-florinef mean evening cortisol) at baseline
Time 2 (post- mife or placebo treatment) = Difference in cortisol level from Day 22 (pre-florinef mean evening cortisol) and Day 23 (post-florinef mean evening cortisol level).
All measurements were the percent change in mean cortisol level from 6 pm to 10 pm. Cortisol levels are expressed as ug/dL
Percent change in cortisol decrease between Time 2 and Time 1 post florinef should be greater with mifepristone than placebo, reflecting enhanced mineralocorticoid receptor activity.
