title: Exploring the Role of Social Anhedonia in the Positive and Negative Dimensions of Schizotypy in a Non-Clinical Sample.
abstract: BACKGROUND
  The present study aimed to investigate the role of social anhedonia, defined as the lack of ability to feel pleasure from interpersonal relationship, in a multidimensional model of schizotypy and to determine the psychometric properties of the Turkish version of Chapman's Revised Social Anhedonia Scale (SAS) in a non-clinical sample.
  
  
  METHODS
  Second-grade students of Ankara University Medical Faculty were recruited (n=266, Mage=20.28). Confirmatory factor analysis was performed to test schizotypy dimensions. The Cronbach's alpha internal consistency value, test-retest reliability and congruent validity of SAS were calculated.
  
  
  RESULTS
  The model in which social anhedonia was allowed to load on both schizotypy dimensions fit the data set better than the model in which social anhedonia was allowed to load on negative dimension alone. The internal consistency assessed with Cronbach's alpha was .84, test-retest reliability was r=.76 and the congruent validity of SAS was r=.55.
  
  
  CONCLUSIONS
  The results of current study were consistent with those of earlier studies showing that social anhedonia was related to both schizotypy dimensions. Furthermore, the psychometric properties of the Turkish Version of SAS revealed that it is a reliable and valid measurement to assess social anhedonia in a non-clinical population.
