Abilify as an Adjunctive Treatment for Refractory Depression.

• Clinical Global Impressions Scale (CGI)
• Global Assessment of Functioning Scale (GAFS)
• Beck Depression Inventory (BDI)

This is a study of the effectiveness of adding Abilify (aripiprazole), an atypical antipsychotic medication, to ongoing SSRI antidepressant treatment for depressed outpatients who are not responding fully to SSRI treatment alone. It is hypothesized that patients’ functioning will improve after 12 weeks of treatment with Aripiprazole and SSRI medication.

This is a pilot study of the effectiveness of adding Abilify (aripiprazole), an atypical antipsychotic medication, to ongoing SSRI antidepressant treatment for depressed outpatients who are not responding fully to SSRI treatment alone. Fifteen subjects will be given aripiprazole in a flexible dosing schedule and followed for 12 weeks, while continuing their ongoing SSRI medication. Assessments of depressive symptoms, overall functioning, social functioning, and side effects will be completed. It is hypothesized that patients’ functioning will improve after 12 weeks of treatment with Aripiprazole and SSRI medication.
