Anhedonia, a central dimension within the schizotypy construct, has been considered to be a promising vulnerability marker for schizophrenia-spectrum disorders. The Revised Physical Anhedonia Scale (RPhA) and Revised Social Anhedonia Scale (RSAS) are two self-reports widely used in the assessment of anhedonia; however, they psychometric characteristics have been scarcely investigated in Spanish population. The objective of the current work was to study the psychometric properties of the Revised Physical and Social Anhedonia Scales in non-clinical young adults. The sample was composed of 728 college students with a mean age of 20.1 years (SD = 2.5). The data indicated that the scales showed adequate psychometric characteristics. The Cronbach alpha was 0.95 (RSAS) and 0.92 (RPhA) respectively. The confirmatory factor analysis carried out on the matrix of tetrachoric correlations showed that both scales presented an essentially unidimensional solution. The Revised Physical and Social Anhedonia Scales seem to be adequate for psychosis-risk assessment in non-clinical populations. Future research should further investigate the construct validity in other populations and cultures as well as study its relation to emotional aspects and cognitive endophenotypes.
快感缺失是精神分裂症型人格结构的一个核心维度，被认为是精神分裂症谱系障碍一个很有前景的易感性标志物。修订版身体快感缺失量表（RPhA）和修订版社交快感缺失量表（RSAS）是广泛用于评估快感缺失的两个自评量表；然而，它们的心理测量学特征在西班牙人群中几乎未被研究过。当前这项研究的目的是探讨修订版身体快感缺失量表和社交快感缺失量表在非临床年轻成年人中的心理测量学特性。样本由728名大学生组成，平均年龄为20.1岁（标准差=2.5）。数据表明，这两个量表显示出了足够的心理测量学特征。克朗巴哈α系数分别为0.95（RSAS）和0.92（RPhA）。对四分相关矩阵进行的验证性因素分析表明，两个量表均呈现出基本单维的解决方案。修订版身体快感缺失量表和社交快感缺失量表似乎适用于非临床人群的精神病风险评估。未来的研究应进一步探讨其在其他人群和文化中的结构效度，并研究其与情感方面和认知内表型的关系。
