About this trial
The goal of this single-center, single-blind, randomized, controlled, parallel group, interventional trial is to evaluate antidepressant efficacy of yoga monotherapy of 12-weeks duration in 180 adults meeting diagnostic criteria for mild-to-moderate major depression at the Zuckerberg San Francisco General Hospital. Researchers will compare the yoga interventions to an education control intervention on holistic healthcare.

Trial outcomes
Primary outcomes
Change in Beck Depression Inventory-II score
The Beck Depression Inventory-II is one of the most commonly used instruments in psychiatric research; it has been translated and validated in many different languages, appearing in hundreds of studies worldwide. The Beck Depression Inventory-II is a 21-item validated instrument for the self-report of depressive symptoms; it can typically be completed in 5 minutes. Each item on the Beck Depression Inventory-II can be scored from 0 to 3, with the total score derived by summing the individual item scores. A total score of 14-19 suggests mild depression, 20-28 suggests moderate depression, and 29-63 suggests severe depression.
Secondary outcomes
