title: Post-traumatic psychological changes among survivors of the Lushan earthquake living in the most affected areas.
abstract: The primary objective of our study was to investigate both the negative and positive psychological changes following the Lushan earthquake, and to explore the factors associated with psychological changes. Multi-stage random sampling was used to select respondents from Lushan County, Sichuan Province, China. A simplified Chinese version of the short form of Changes in Outlook Questionnaire (CiOQ-S) was used to assess psychological changes in earthquake survivors. Descriptive statistics, t-tests, ANOVA and stepwise linear regression analysis were used for data analysis. A total of 4972 respondents were investigated in the cross-sectional study. The mean scores of the positive and negative psychological changes were 26.61 and 8.12, respectively. The factors associated with positive psychological changes included ethnic minority, high level of education, high household income, not injured in the earthquake, not trapped during the earthquake, and having experienced the Wenchuan earthquake. The factors associated with negative psychological changes included female gender, ethnic minority, low household income, history of diseases, injured during the earthquake, and trapped during the earthquake. The current analysis helps expand our knowledge of the negative and positive psychological changes that may occur following an earthquake experience.
