In today’s society, social anxiety disorder has become a major psychological problem affecting People’s Daily life quality in recent years, especially among college students. Because of its collective and communicative characteristics, the collegiate instrumental ensemble is considered to be effective in alleviating social anxiety.

This study adopted a randomized controlled experiment design and selected 200 freshmen from a university as the research objects. According to the principle of voluntary, the students with social anxiety characteristics were randomly divided into two groups to be included in the study. The control group received routine psychological counseling, while the intervention group participated in the study and research of ethnic instrumental ensemble. The activity cycle was one semester, and ensemble training was conducted 3 times a week for 2 hours each time. In this study, two groups of students were measured before and after using the social anxiety scale. The analysis tool is SPSS23.0.

After one semester of study, it was found that the anxiety of students in the intervention group was significantly reduced, and the anxiety degree was more significantly decreased than that of the control group (P<0.01). The social anxiety level of the students in the intervention group remained relatively low during the three-month follow-up interview after the teaching.

The teaching of ethnic instrumental ensemble in colleges and universities can help alleviate the social anxiety of college students, improve their social ability and optimize the environment of campus mental health education.
