title: [Translation and validation of the Revised Social Anhedonia Scale (SAS Social Anhedonia Scale, M.L. Eckblad, L.J. Chapman et al., 1982). Study of the internal and concurrent validity in 126 normal subjects].
abstract: The Revised Social Anhedonia Scale (SAS) with 40 items (Eckblad et al., 1982) which studies the social dimension of anhedonia has been validated in the United-States (Mishlove & Chapman, 1985). However, no french translation and validation of this scale has been made to date. This work presents the french translation of the Social Anhedonia Scale and its validation. After a back-translation and final adjustment, it has been submitted to a sample of 126 control subjects from the general population. Furthermore, they were asked to fill two other scales: the Chapman Physical Anhedonia (PAS) with 61 items and the Fawcett Pleasure Scale (36 items), both of them exploring the subjects answer in terms of anhedonia/hedonia towards social, sensorial and/or physical experiences. The internal validity has been determined on the one hand by the Cronbach alpha coefficient which showed a strong unidimensional characteristic (0.80) and the other hand by the correlation of each item with the total score using the point biserial coefficient which ranged from .204 to .559. The concurrent validation has been determined by the Pearson correlation coefficient between the french version of social anhedonia scale and the french version of physical anhedonia scale. The values were .42, p = .001. Furthermore, this two scales are significant inversely correled to the french version of the pleasure scale: r = -.22, p = .0125 for the first, and r = -.26, p = .0027 for the second. The internal and concurrent validity of the french version of the revised social anhedonia scale should allow to improve our understanding of anhedonia in psychiatry and psychopathology.
