Abstract：While facing the huge earthquake, the physical and psychological assistance for victims is deemed necessary. Exploring the physical and psychological symptoms for different types of victims is beneficial to reduce the impact of disasters and improve the effect of the assistance. The physical and psychological stress symptoms are characterized by four indicators based on the prior related literature, namely, physical symptoms, cognitive symptoms, emotional symptoms, and behavioral symptoms. The catastrophe progression method is applied to build a physical and psychological stress symptoms catastrophe model for the earthquake victims and "5.12" Wenchuan earthquake is used as an example for the empirical research. According to demographic characteristics, the victims of Wenchuan earthquake are categorized by gender, age, and extent of earthquake impact. The impact of the earthquake on different types of victims is analyzed and it is found that the biggest impact is on the earthquake victims of female, the middle-and-old age, and people in worst-hit region. Facing with the same disaster, the same type of people exhibits different physical symptoms, cognitive symptoms, emotional symptoms, and behavioral symptoms. The catastrophe progression method for the physical and psychological stress symptoms model is adopted to analyze the physical and mental stress symptoms of earthquake victims, its results are in consistent with previous related research conclusion. It is indicated that the model is reliable and effective for such problems, thus the model provides a new method for the post-disaster relief work.
