[Abstract] Objective: To understand the post-disaster psychological state of the residents affected by the earthquake in Yangbi County, Dali Prefecture, Yunnan Province, and to analyze the influencing factors. Methods: The psychological state, stress condition, and sleep status of disaster-affected residents were investigated using the Impact of Event Scale-Revised (IES-R), the Social Support Rating Scale (SSRS), the Hospital Anxiety and Depression Scale (HADS), and the Pittsburgh Sleep Quality Index (PSQI). Data analysis was conducted using the Mann-Whitney U test, chi-square test, Spearman's correlation, and multiple stepwise linear regression. Results: This study evaluated the psychological health status of 389 residents affected by the disaster. The findings indicated that one month post-disaster, the detection rates for the Impact of Event Scale-Revised (IES-R), anxiety subscale, depression subscale, and Pittsburgh Sleep Quality Index (PSQI) were 59.1%, 35.7%, 33.4%, and 49.4%, respectively. Multivariate stepwise linear regression analysis showed that being female, having poor family economic status, living in rural areas, experiencing severe trauma, having significant house damage, and incurring substantial property loss were significantly negatively correlated with the total score of IES-R. In contrast, the total score of PSQI was significantly positively correlated with the total score of IES-R (R²=0.37, F=27.30, P<0.01).Conclusion: Following the earthquake, residents in the disaster area are experiencing high levels of stress responses, with influencing factors encompassing sociodemographic characteristics and earthquake disaster features. Symptomatic post-traumatic stress disorder (PTSD), anxiety, depression, and sleep disturbances interact with each other, collectively impairing the psychological stress responses of the affected population.
