Methods: 80 rural left behind elderly people who had a Geriatric Depression Scale(GDS) score between 11 and 25 will be recruited and randomly assigned to the intervention (n=40) and control group(n=40). The intervention group will be received both MBAT and treatment-as-usual for 8 weeks while the control group received treatment-as-usual. Both groups will be assessed with the GDS, Beck Anxiety Inventory (BAI), and Oxford Happiness Questionnaire (OHQ) at baseline, immediately post-intervention, and at 3 months post-intervention.
