Resumo

Anhedonia has been hypothesized as a latent trait underlying risk for schizophrenia-spectrum disorders. The main goal of the present study was to analyze the psychometric properties of the brief versions of the Physical Anhedonia Scale (PhyS-B) and the Revised Social Anhedonia Scale (RSAS-B). The final sample comprised a total of 1349 college students divided into two subsamples (n1=710; n2=639). Results showed that both instruments have adequate psychometric properties under Classical Test Theory and Item Response Theory frameworks. Internal structure analysis of PhyS-B and RSAS-B scores, through exploratory and confirmatory factor analysis, yielded an essentially one-dimensional solution. Cronbach's alpha coefficient for the total score of PhyS-B ranged between 0.86 and 0.87, and between 0.88 and 0.94 for the RSAS-B. Several items showed differential functioning by gender. The results indicate that the short version of the Physical and Social Anhedonia Scales show adequate psychometric properties for the assessment of the negative dimension of schizotypy in this sample of young adults. Replication and follow-up studies are necessary to confirm the validity and clinical relevance of these scales. © 2015 by Nova Science Publishers, Inc. All rights reserved.
