title: The composition of the depressive syndrome in acute schizophrenia.
abstract: The composition of the depressive syndrome was examined at both the acute and chronic phases of schizophrenic illness in 86 newly admitted patients. A subgroup with pronounced depression was defined, and a discriminant analysis was performed using symptoms from the Hamilton Rating Scale for Depression (HRSD) as discriminant variables. At the acute phase, the following nine symptoms from the HRSD were significant: depressed mood, guilt, suicide, retardation, three types of insomnia, and two somatic symptoms. At the chronic stable phase, only four symptoms were significant: depressed mood, suicide, general somatic symptoms, and loss of weight. Initial insomnia, middle insomnia, genital symptoms, and loss of insight were poorly correlated. The positive and negative symptoms and extrapyramidal side-effects were not discriminators at either phase. These findings suggest that only certain items from the HRSD may be crucial when assessing depression in schizophrenia.
