Hedonic capacity and schizotypy revisited: A taxometric analysis of socialanhedonia

P. E. Meehl (1962) originally conjectured that hedonic capacity was an indi cator of the latent class or taxon of schizotypy. However, P. E. Meehl (198 9, 1990) subsequently diminished the role of hedonic capacity in his theory , indicating that hypohedonia is one of a dozen normal-range (nontaxonic) i ndividual-differences factors that may potentiate the expression of schizop hrenia. This dimensional-only view of hedonic capacity was tested by applyi ng 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 measur ed by the RSAS is taxonic in nature with a base rate approximating .10. The se data are interpreted in the context of other findings suggesting that so cial anhedonia is an indicator of schizotypy.
