Abstract：
The aim of this research is to analyze the impact of mental health on the academic performance of junior and senior students studying in a university setting during the 2022-2023 academic year, in the post-COVID period. The study was conducted in Beijing, China, with the participation of 600 students, including 300 first-year students and 300 fifth-year students. DASS (Depression, Anxiety, and Stress Scale) and PHQ-9 (Patient Health Questionnaire-9) questionnaires were employed to measure mental health. The DASS assesses symptoms of depression, anxiety, and stress, while the PHQ-9 specifically evaluates depression severity. Academic performance was evaluated using a 12-point scale, which incorporated various criteria such as exam scores, coursework performance, and participation in extracurricular activities. The research was conducted across five faculties of the university from 2022 to 2023. In the study, fifth-year students demonstrated a higher level of mental health compared to first-year students, with an average DASS score of 27.1 and 24.2, respectively. Interestingly, despite this, first-year students achieved higher academic performance indicators, with an average score of 8.2 compared to 9.8 in fifth-year students. Correlation analysis revealed significant associations between stress, depression, and anxiety levels with academic performance (stress: r = -0.25, p < 0.001; depression: r = -0.20, p = 0.003; anxiety: r = -0.18, p = 0.008). These findings highlight the critical importance of addressing students\' mental well-being, particularly in later academic years. Recommendations include implementing support programs and developing online resources for students.
摘要：
这项研究的目的是分析心理健康对2022-2023学年在大学环境中学习的初中和高中学生学习成绩的影响，在后COVID时期。这项研究是在北京进行的，中国,在600名学生的参与下，包括300名一年级学生和300名五年级学生。DASS(抑郁症，焦虑,和压力量表）和PHQ-9（患者健康问卷-9）问卷用于测量心理健康。DASS评估抑郁症的症状，焦虑,和压力，而PHQ-9专门评估抑郁症的严重程度。学业成绩采用12分量表进行评估，其中结合了各种标准，如考试成绩，课程表现,参加课外活动。该研究于2022年至2023年在该大学的五个学院进行。在研究中,与一年级学生相比，五年级学生表现出更高的心理健康水平，平均DASS评分分别为27.1和24.2。有趣的是,尽管如此,一年级学生取得了更高的学习成绩指标，平均得分为8.2分，而五年级学生为9.8分。相关分析显示压力之间存在显著关联，抑郁症,和焦虑水平与学业成绩（压力：r=-0.25，p<0.001；抑郁：r=-0.20，p=0.003；焦虑：r=-0.18，p=0.008）。这些发现强调了解决学生心理健康问题的关键重要性，尤其是在后来的学术时代。建议包括实施支持计划和为学生开发在线资源。
