title: Lexical Characteristics of Anticipatory and Consummatory Anhedonia in Schizophrenia: A Study of Language in Spontaneous Life Narratives.
abstract: OBJECTIVE
  The extent to which anticipatory anhedonia (an important determinant of outcome in schizophrenia) is determined by interpersonal characteristics, cognitive biases, or even artifacts of measurement remains unclear. The present study aims to provide understanding cognitive, affective and phenomenological characteristics of this construct by examining the lexical characteristics of life narratives with schizophrenia with computerized lexical analysis.
  
  
  METHODS
  A total of 41 individuals with a diagnosis of schizophrenia or schizoaffective disorder completed the Indiana Psychiatric Illness Interview, and the lexical characteristics of these narratives were examined for their relationships to both anticipatory and consummatory anhedonia.
  
  
  RESULTS
  Results revealed that relatively higher levels of both anticipatory and consummatory anhedonia were linked with fewer past-related words and by lesser use of first-person plural pronouns.
  
  
  CONCLUSIONS
  This may suggest anhedonia is linked to diminished access to past narrative episodes and a lesser sense of shared important moments with others.
