MMPI Results Associated with Abnormal Responses to the DST and TRH Tests

In the present study, it was predicted that psychiatric inpatients who obtained abnormal responses on the Dexamethasone Suppression Test (DST) and the Thyrotropin Releasing Hormone Stimulation Test (TRH) would obtain higher elevations on the MMPI scales associated with depressive symptomatology than inpatients with normal DST and TRH responses. Patients with abnormal DST responses obtained significantly lower scores on the F, Psychopathic Deviate, and Paranoia scales, suggesting that they present themselves on the MMPI as less socially maladjusted, and less alienated from societal values than their depressed inpatient peers who obtained normal DST results. No differences were obtained between abnormal and normal responders on either the DST or TRH with respect to the MMPI scales that are typically associated with depression.
