title: Correlations over time between dysphoric mood and symptomatology in schizophrenia.
abstract: Monthly assessments of depression, anxiety, and positive and negative symptoms of schizophrenia were performed on 52 schizophrenic patients over periods ranging from 12 to 29 months. Data were analyzed to assess the extent to which symptoms of dysphoria (anxiety and depression) were more strongly related to negative or positive symptoms of schizophrenia. Consistent with past research using comparisons across subjects, the current longitudinal data show that there is a more consistent relationship between dysphoria and positive rather than negative symptoms.
