Depression and anxiety among the older adults is an issue that cannot be ignored at present. Compared to traditional pharmacological treatments and electroconvulsive therapy, non pharmacological treatments with fewer side effects, such as music-based intervention, are also effective and more easily accepted for the treatment of depression and anxiety in the older adults. In China, there have been some researches conducted Chinese five elements music as a clinical treatment for relieving depression and anxiety disorders in patients. However, there is few research on the impact of Chinese five elements music-based intervention based on midnight-noon ebb-flow theory on depression and anxiety in the older adults. This study investigated the intervention effect of Chinese five elements music-based intervention accompanied by midnight-noon ebb-flow theory on depression and anxiety in older adults.

This study investigated the intervention effect of Chinese five elements music-based intervention accompanied by midnight-noon ebb-flow theory on depression and anxiety in older adults. This study intervened in music-based intervention for 86 older adults with depression and anxiety, and divided the 86 subjects into an experimental group (with Chinese five elements music based on midnight-noon ebb-flow theory) and a control group (with Chinese five elements music). This study used the Hamilton Depression Scale, Hamilton Anxiety Scale, and the Quality of Life Enjoyment and Satisfaction Questionnaire as assessment instruments after the intervention. According to the evaluation results, it was found that compared with traditional Chinese five elements music, the intervention of Chinese five elements music with midnight-noon ebb-flow theory is more effective in alleviating depression in the older adults. This study will provide a scientific basis for further study of the timing mechanism of the five elements theory and further advance the benefits of Traditional Chinese Time Medicine.
