in the anticipatory but not the consummatory subscale of the TEPS. FBF mediate the relationship between S and all the Anhedonia Scales. FBF Memory and Overstimulation subscales were the greatest predictors of all the anhedonia scores in the S group. We suppose that these experiences prevent patients from retaining a positive experience from past pleasant activities and, consequently, the lack of anticipatory pleasure would represent an avoidance of potentially stressing new scenarios. Conclusion: Considering the primary nature of BS, anhedonia in schizophrenic patients could be seen as a secondary phenomenon.
