This study will use a randomized parallel-group design to compare the safety, efficacy, and tolerability of electroacupuncture (EA) and sham electroacupuncture (SA) for the treatment of major depression. Over a 15-month period, 60 adult outpatients with a major depressive disorder of mild or moderate severity (as defined by the DSM-IV) will be randomized to either 12 sessions of EA or SA to be provided over 6 weeks. Safety and symptomatic improvement (as measured with the Hamilton Rating Scale for Depression [HRSD]) will constitute the primary outcome measures. Tolerability and functional improvement will constitute secondary outcome measures.
