A substantial body of research suggests that subclinical symptoms characterize the longitudinal course of major depression and have important pathophysiological and treatment implications. Specific treatment of residual symptoms may in fact improve longterm outcome, by acting on those residual symptoms that progress to become prodromes of relapse. The assessment of psychological well-being is also important, since its absence may create conditions of vulnerability to possible adversities. The route of recovery, thus, lies not exclusively in alleviating the negative, but in engendering the positive.
