Anticipatory and consummatory components of the experience of pleasure in schizophrenia: cross-cultural validation and extension.Psychiatry Res. 2010 Jan 30; 175(1-2):181-3.PR
This study examined anticipatory and consummatory pleasure in schizophrenia patients with and without negative symptoms. Negative symptom patients experienced less anticipatory pleasure than non-negative symptom patients; only one facet of consummatory pleasure was unaffected in negative schizophrenia. Greater pleasure deficits were correlated with more severe positive and negative symptoms.
