title: The frequency of associations between positive and negative symptoms and dysphoria in schizophrenia.
abstract: Weekly assessments of depression, anxiety, and positive and negative symptoms were performed on 80 subjects with schizophrenia or schizoaffective disorder. Using procedures previously reported in another study, the frequency of significant correlations between the sum of anxiety and depression ratings and positive symptoms was compared with the frequency of significant correlations between the sum of anxiety and depression ratings and negative symptoms. Results confirm that dysphoria in schizophrenia tends to be more frequently associated with positive versus negative symptoms, regardless of diagnostic subtype or symptom type. This provides further evidence of the independence of negative symptoms from dysphoria and suggests that the level of positive symptoms and level of dysphoria may mutually influence one another.
