【摘要】 目的 针对现有研究对医学生群体关注不足的问题，以成都某高校的医学生为对象，探究其心理健康的影响因素及与生命意义感、心理韧性的关联，为医学生心理健康教育提供参考。方法 采用生命意义感量表、心理韧性量表及症状自评量表（SCL-90）作为测量工具，以成都市某高校的医学生为研究对象，采用随机抽样法开展问卷调查，最终回收有效问卷910份。通过SPSS 25.0、AMOS 24.0进行统计分析。结果 医学生心理健康中等偏下，躯体化、抑郁、焦虑、敌对、恐怖、偏执及精神病性因子得分高于国内大学生常模；男生生命意义感、心理韧性及心理健康水平均优于女生；生命意义感与心理韧性正相关，二者均与SCL-90得分负相关；心理韧性在生命意义感与心理健康水平间起中介作用（占比35.10%），模型拟合良好。结论 医学生心理健康需关注，存在性别差异；生命意义感可直接或通过增强心理韧性，间接提升其心理健康水平。更多还原

【Abstract】 Objective Addressing the insufficient attention paid to medical students in existing studies, this study recruited medical students from a university in Chengdu as participants. It explored the influencing factors of their mental health and the correlations with sense of life meaning and psychological resilience, aiming to provide references for mental health education of medical students. Methods The sense of life meaning scale, psychological resilience scale, and symptom check list-90(SCL-90) were used as measurement tools. Medical students from a university in Chengdu were selected as participants, and a questionnaire survey was conducted using the random sampling method. Finally, 910 valid questionnaires were recovered. Statistical analyses were conducted using SPSS 25.0 and AMOS 24.0. Results The mental health level of medical students was below average; the scores of seven factors including somatization, depression, anxiety, hostility, phobia, paranoia and psychoticism were higher than the national norm for college students. Male students showed better performance in sense of life meaning, psychological resilience, and mental health level than female students. Sense of life meaning was positively correlated with psychological resilience, and both were negatively correlated with the SCL-90 score. Psychological resilience played a mediating role between sense of life meaning and mental health level(accounting for 35.10%), and the model showed good fit. Conclusion The mental health of medical students requires attention and exhibits gender differences. Sense of life meaning can directly enhance their mental health level, or indirectly do so by strengthening psychological resilience.更多还原
