Analysis of College Students’ psychological Anxiety and Its Causes under COVID-19

Due to the global outbreak of COVID-19, universities have postponed the commencement of 2020 spring semester and adopted online learning when students and staff are self-quarantined at home. In this paper, SAS(Self-Rating Anxiety Scale) was used to evaluate and analyze students’ anxiety in one of the Top 20 universities in China. A total of 3,611 valid questionnaires from 34 provincial administrative regions and Taiwan in China were collected. FP-Growth was used to mine association rules for the scores of each item in SAS. K-Means was adopted to divide all samples into three categories and analyze the scoring characteristics of each SAS item in each category. Based on BiLSTM, a Chinese sentiment analysis model was constructed to analyze the text data. The results show that the average scores of the forward scoring items were relatively high. For the anxious samples, there were fewer arms and legs tingling, arms and legs trembling and syncope. The main causes of anxiety among college students included online learning and epidemic diseases.
