ANHEDONIA AND BLUNTED AFFECT IN MAJOR DEPRESSIVE DISORDER

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.
