Brief summary:
This study will determine whether adding interpersonal psychotherapy to treatment with the antidepressant escitalopram will be more effective in reducing symptoms of depression than antidepressant medication alone.

Detailed description:
The purpose of this research study is to learn if adding psychotherapy (Interpersonal Psychotherapy) to antidepressant medication (escitalopram), will be more effective in reducing lingering symptoms of depression and decreasing the burden of these symptoms, when initial treatment with just antidepressant medication alone has led to only a partial response. Participation in the study will last up to 22 weeks.

Because fewer than 50% of elderly depressed patients achieve remission and recovery in response to first-line antidepressant pharmacotherapy, the majority of patients are left with significant symptoms and functional impairment, putting them at risk of chronic, relapsing illness, non-adherence to other medical treatment, suicide, and family caregiver burden. We will recruit and treat 320 patients with unipolar major depression aged 60 and older, using clinical management with escitalopram 10 mg/day for six weeks. Patients who are partial responders to escitalopram plus clinical management will be randomly assigned to 16 weeks of extension therapy with either 20 mg escitalopram plus clinical management or 20 mg escitalopram plus Interpersonal Psychotherapy (IPT, 16 sessions). Changes over time in measures of depressive symptoms, hopelessness, suicidal ideation, disability, and family caregiving burden will be assessed. This study will answer the question of how best to treat partial responders-by simply extending pharmacotherapy at higher doses, or by also adding psychotherapy-to remission and recovery.
