2020年新型冠狀病毒 (COVID-19)疫情的爆發，已經破壞了全球人民的日常生活，人民對於COVID-19大流行產生負面的心理反應，例如焦慮、畏懼等等，使各國不得不重視防疫行為防止擴散。本研究根據刺激-有機體-反應(SOR)模型發展研究模型，探討資訊性與嚴重性是否影響民眾的焦慮與認知同化，接者探討在民眾的心理狀態受到影響後，是否會觸發他們實施衛生行為與社交距離以及探討研究模型是否存在中介反應。
本研究樣本以線上問卷方式收集，利用分層抽樣搭配配額抽樣方法，根據台灣各年齡層人數分配樣本數，總共回收818份有效樣本。研究結果顯示資訊性、嚴重性對焦慮與認知同化有正向影響關係，焦慮與認知同化對衛生行為與社交距離有正向影響關係，其中焦慮對於兩種外部刺激與兩種行為反應均具有中介效果，而認知同化僅在資訊性對社交距離有中介效果。
本研究有助於相關單位，了解民眾在面對疫情的行為，未來對於類似的傳染病疫情可以提供更好的防疫政策。

The novel Coronavirus (COVID-19) outbreak in 2020 has disrupted the daily lives of people around the world. Negative psychological reactions to the COVID-19 pandemic, such as anxiety, fear, etc., have forced countries to focus on preventive measures to prevent the spread of the virus. In this study, we used the stimulus-organic-response (SOR) theory to development our research model, to explore whether Informativeness and severity affect people's anxiety and cognitive assimilation. After that, we explored whether people's psychological state was affected, triggering the implementation of hygiene behaviors and social distancing, and whether there was a mediating response in the research model.
The sample for this study was collected through an online questionnaire. We using stratified sampling and quota sampling, the number of samples was allocated according to the population of each age group in Taiwan, and a total of 818 valid samples were recovered. The results of the study showed that informativeness and severity had a positive impact on anxiety and cognitive assimilation, anxiety and cognitive assimilation had a positive impact on hygiene behavior and social distance. Anxiety has mediating effects on both external stimuli and behavioral responses, while cognitive assimilation has mediating effects on social distance only in information.
This study is helpful for relevant units to understand the behavior of the public in the face of the epidemic, so as to provide better epidemic prevention policies for similar epidemic outbreaks in the future.
