The relation between anhedonia and affective flattening was studied in 61 normal subjects and 61 major depressives. Affective flattening and anhedonia were defined by the following self-rating scales: Fawcett-Clark Pleasure Capacity Scale (FCPCS), Hardy Displeasure Capacity Scale (HDCS), FCPCS-PP (subscale of physical pleasure), and HDCS-PD (subscale of physical displeasure). The depressives are more sensitive to displeasure and more anhedonic than controls. Concerning physical stimulations (FCPCS-PP and HDCS-PD) in the depressed group, anhedonia and affective flattening are not linked, suggesting that physical anhedonia is not secondary to low emotional reactivity (affective flattening) and constitutes an independent dimension.
