TI  - Psychosis-predictive value of self-reported schizotypy in a clinical high-risk 
      sample.

AB  - [Correction Notice: An Erratum for this article was reported in Vol 125(7) of 
      Journal of Abnormal Psychology (see record 2016-47529-004). In the article, there 
      was an error in the Author Note. The affiliation of Daniela Hubl was incorrectly 
      listed as "University Hospital of Child and Adolescent Psychiatry and 
      Psychotherapy, University of Bern." It should have been listed as "University 
      Hospital of Psychiatry and Psychotherapy, University of Bern." All versions of 
      this article have been corrected.] Schizotypy is considered an indicator of 
      psychosis-proneness and therefore, a precursor to schizophrenia-spectrum 
      psychosis. In the early detection of psychosis, the widely used ultra high-risk 
      criteria refer to the positive features of schizotypy and schizotypal personality 
      disorders (SPD). In clinical high risk (CHR) samples, self-reported or clinically 
      assessed SPD, notably the lack of close friends, has been suggested to facilitate 
      the prediction of psychosis. In community samples, self-reported schizotypy has 
      mainly been assessed psychometrically using the 4 Wisconsin Schizotypy Scales 
      (WSS; Chapman, Chapman, Kwapil, Eckbald, & Zinser, 1994), and the positive 
      schizotypy dimension was consistently predictive of psychosis (Debbane et al., 
      2015). However, psychometrically assessed schizotypy has not yet been studied as 
      a potential predictor of psychosis in CHR samples. To bridge this gap, we studied 
      the psychosis-predictive value of 3 of the WSSs and their association with CHR 
      state in a clinical sample. One hundred 28 patients (23 +/- 7 years; 81% considered 
      CHR) from 2 early detection services were followed for 12 to 101 months. Within 
      48 months, 36 (28.1%) converted to psychosis. Only physical anhedonia was 
      associated with CHR state, and high scores for physical anhedonia were predictive 
      of conversion in conjunction with the CHR state. Physical anhedonia rather than 
      positive schizotypy scales might separate future converters from nonconverters in 
      clinical samples already presenting a phenomenologically more extreme range on 
      the psychosis continuum. Given their reported psychosis-predictive value in 
      nonclinical samples, psychometric schizotypy measures in general might be useful 
      for the initial screening of psychosis-proneness in the community, whereas 
      physical anhedonia might be particularly useful in CHR samples. (PsycINFO
