2ND STUDY OF VALIDATION OF THE FRENCH VER SION OF THE PHYSICAL ANHEDONIA SCALE (PAS) IN 356 SUBJECTS

This work presents a second study of validation of the French version of the Physical Anhedonia Scale (PAS) in four groups (221 and 32 norma l subjects, 61 schizophrenics (RDC) and 42 major depressives (RDC). Th e internal consistency was determined by the Kuder-Richardson coeffici ent (KR 20) which values was 0.75 in the normal group and 0.82 in the schizophrenic group. The mean of the correlations between each item an d the total score was 0.25. The concurrent validity was studied by the correlation coefficient between the PAS score and a sub-scale of phys ical pleasure (FCPCS-PP) extracted from the Fawcett Clark Pleasure Cap acity Scale. The values were - 0.39 (p < 0.01) in the normal groups, - 0.37 (p < 0.01) in the schizophrenic group and - 0.56 (p < 0.01) in t he depressive group. A test retest have shown a value of 0.76 (p < 0.0 1) between two passations (3 weeks) of the PAS. The norms of PAS in th e French population were given.
