Social Fear

This clinical trial aims to evaluate the efficacy and safety of transcutaneous auricular vagus nerve stimulation (taVNS) in patients with social anxiety disorder (SAD). The study addresses the following key research questions: * Does taVNS demonstrate preliminary clinical efficacy in the treatment of SAD? * What adverse events may occur during taVNS treatment, and what is the treatment compliance of the subjects?

The purpose of the study is to investigate the effects of four versions of a workshop for social anxiety and public speaking stress. All participants are current University of Colorado Boulder undergraduate students. Participation in this research study lasts for approximately 8 weeks, and includes a pre-workshop questionnaire, 3 weekly workshop sessions (ranging from 2 to 3 hours each, including a 5-minute post-session questionnaire), a post-workshop questionnaire, and a 1-month follow-up questionnaire.
