International audience. The aim of the study is to explore the validity and the reliability of the French version of the SHAPS in two groups of subjects. 208 healthy students and 103 inpatients meeting the RDC criteria for schizophrenia or depression filled out the French versions of the SHAPS and the revised Physical Anhedonia Scale of Chapman and Chapman. The internal consistency of the SHAPS was measured in each group using first the Kuder Richardson coefficient (point biserial) between the items and the total score. The concurrent validity was studied using the Pearson correlation coefficient between the SHAPS and the PAS in each group. The predictive validity was determined by the comparison of the SHAPS score between the two groups. The reliability was studied using a test-retest in a sub-group (n = 32) extracted of the control group. The values of the KR 20 in the healthy and psychiatric groups were respectively 0.47 and 0.80. The mean of the correlations between the items and the total score were respectively 0.35 and 0.52. The values of the correlations between the SHAPS and the PAS were respectively in the normal and psychiatric groups 0.39 (p < 0.001) and 0.34 (p < 0.001). Psychiatric subjects had a higher score (m = 2.33, sd = 2.68) on the SHAPS than the normals (m = 0.89, sd = 1.18) [F (1,303) = 12.26, p = 0.0005]. The test-retest showed a correlation of 0.56 (p < 0.01) between the two passations of the SHAPS. The metrological parameters of the SHAPS were discussed as well as the utility of that scale compared to the PAS.
