Role of serotonin and noradrenaline in social dysfunction: a review of data on reboxetine and the Social Adaptation Self-evaluation Scale (SASS).
Social impairment is a common feature of depressive illness, often causing substantial and clinically meaningful dysfunction. Although the depressive symptoms and social impairment are linked, the naturalistic course and response to treatment of these two aspects of depression do not necessarily correlate. A variety of self-report and clinician-administered assessment scales which are specific for the measurement of social functioning and have good psychometric properties have been developed in the past 40 years. The most recent of these instruments is the Social Adaptation Self-evaluation Scale (SASS), a 21-item scale designed in 1989 to assess patient response to antidepressant treatment. SASS was used in two clinical trials comparing reboxetine, the new selective noradrenaline reuptake inhibitor (selective NRI), with fluoxetine. While no difference in efficacy was detectable by traditional assessments of symptoms, reboxetine proved to be significantly more effective than fluoxetine in improving social functioning in patients with depression. Reboxetine was also more effective than fluoxetine in rectifying social functioning in the subset of patients who remitted from an episode of major depression. Specifically, reboxetine improved patient motivation, energy and self-perception. These results indicate that antidepressant therapy can achieve more than symptom relief in depression. It is speculated that there may be a difference in the roles played by serotonin and noradrenaline in social functioning.
