P. E. Meehl (1962) 最初推测享乐能力是精神分裂症潜在类别或分类群的指标。然而，P. E. Meehl (1989, 1990) 随后削弱了享乐能力在他的理论中的作用，表明享乐减退是可能增强精神分裂症表达的十几个正常范围（非分类）个体差异因素之一。通过将分类程序应用于修订版社会快感缺失量表（RSAS；M. L. Eckblad、L. J. Chapman、J. P. Chapman 和 M. Mishlove，1982），在大学生样本（N = 1,526）中测试了这种享乐能力的唯维度观点。分析表明，RSAS 测量的构造本质上是分类学的，基本比率接近 0.10。这些数据是在其他发现的背景下解释的，这些发现表明社交快感缺失是精神分裂症的一个指标。
P. E. Meehl (1962) originally conjectured that hedonic capacity was an indicator of the latent class or taxon of schizotypy. However, P. E. Meehl (1989, 1990) subsequently diminished the role of hedonic capacity in his theory, indicating that hypohedonia is one of a dozen normal-range (nontaxonic) individual-differences factors that may potentiate the expression of schizophrenia. This dimensional-only view of hedonic capacity was tested by applying taxometric procedures to the Revised Social Anhedonia Scale (RSAS; M. L. Eckblad, L. J. Chapman, J. P. Chapman, & M. Mishlove, 1982) in a sample of college students (N = 1,526). Analyses indicated that the construct measured by the RSAS is taxonic in nature with a base rate approximating .10. These data are interpreted in the context of other findings suggesting that social anhedonia is an indicator of schizotypy.
