目的：了解新冠肺炎疫情前后个体的一般心理健康状况变化及产生的心理应激。方法：采用一般健康 问卷（GHQ-12）中文版、应激（压力）反应问卷（SRQ），选取520例居民进行疫情前及疫情期间心理健康状况及 应激反应调查，选择χ2 检验、非参数Z检验及Spearman相关分析进行数据分析。结果：疫情发生后疑似心理 健康障碍检出率增加，为23.46%（122/520），在焦虑/抑郁维度上表现更突出。GHQ-12总分、SRQ总分及各项 因子分差异均有统计学意义。个体对疫情的关注度与GHQ-12及SRQ总分及各项因子分进行Spearman相关 分析结果显示，其与GHQ-12总分及其焦虑/抑郁因子分、SRQ总分及其情绪反应因子、躯体反应因子分均存 在正相关。结论：新冠肺炎疫情使民众疑似心理障碍增加，使个体应激水平增高，对个体心理健康有不利影 响，在情绪方面更明显。个体对疫情过度关注，可能会使个体应激水平升高，不利于个体心理健康。

To investigate changes in the general mental health of individuals before and during the COVID-19 epidemic and psychological stress they generate. Methods: The Chinese version of the General Health Questionnaire (GHQ-12) and the Stress Response Questionnaire (SRQ) were used to investigate the mental health status and stress response before and during the epidemic for 520 selected residents. The Chi-square test, nonparametric Z-test, and Spearman correlation analysis were used for data analysis. Results: After the outbreak, the detection rate of suspected mental health disorders increased to 23.46% (122/520), and this increase was more prominent in the anxiety/depression dimension．There were significant differences in the GHQ-12 total score, SRQ total score, and various factor scores. Results of the Spearman correlation analysis on individuals’concern toward the epidemic and GHQ-12 and SRQ total scores and various factor scores showed a positive correlation between level of concern and GHQ-12 total scores, anxiety/depression factor scores, SRQ total scores, emotional response factor scores, and body response factor scores. Conclusion: The COVID-19 epidemic has brought about a growth in suspected psychological disorders, increased the level of individual stress, and adversely affected the individual's mental health, particularly emotional health. Individuals' excessive concern about the epidemic may increase their level of stress and is not conducive to maintaining mental health．
