 This stepped wedge, randomized controlled trial will test the effectiveness of a Supported Self-Management intervention for depression among adults in Vietnam. The intervention will be delivered at the community level in 8 Vietnamese provinces by primary care providers and social workers. The intervention group will receive the Supported Self-Management intervention, while the control group will receive enhanced treatment as usual. The primary outcome measure for depression is the Self-Reporting Questionnaire-20 SRQ-20. The World Health Organizations Disability Assessment Scale WHODAS 2.00 and the CAGE ConcernCut-down, Anger, Guilt, and Eye-opener measures are also used to assess functional ability and alcohol misuse.
