title: Depression dexamethasone nonsuppression and negative symptoms in schizophrenia.
abstract: This study compared three measures of depression in schizophrenia and their correlation with the Dexamethasone Suppression Test (DST). The degree of overlap of these three measures with negative symptoms was also examined. The Hamilton Depression Rating Scale (HDRS), the depressive syndrome score of the Present State Examination (PSE), and the Scale for the Assessment of Negative Symptoms (SANS) were administered to 50 acutely ill, hospitalized schizophrenics. Patients were diagnosed using DSM-III criteria for schizophrenia. DSM-III criteria were also used to assess the presence of a major depressive episode. Results were that DST nonsuppression was significantly associated with the presence of a major depressive episode, but not with depressive rating scale scores or with negative symptoms. It is concluded that the DST may be of value in differentiating a depressive syndrome from a negative symptom syndrome in schizophrenia.
