Abstract
The aim of the present study is to present a model of depressive vulnerability centered
on anhedonia. After a review of the literature, we suggest a specific symptomatic
profile associating anhedonia, introversion, low sensation-seeking, autonomy, dysfunctional
attitudes, high displeasure capacity, obsessive-compulsive features, passitivity and
pessimism. This symptomatic profile could constitute a mild chronic mood disorder
which, following stress, might decompensate into unipolar endogenomorphic depression.
Several methods of research are suggested to test the validity of our model.
