  1. Multilevel linear regression analyses controlled for the effect of the same address based on multiple imputed data. The values are regression coefficients (with 95 % confidence intervals presented in parentheses). All continuous variables were standardized (M = 0, SD = 1) before being entered into the model as dependent or independent variables. All predictors were measured at 6 months post-disaster
  2. AIC Akaike’s Information Criterion, GPSES General Perceived Self-Efficacy Scale, IES-R Impact of Event Scale-Revised
  3. **p ≤ .01; ***p ≤ .001
  4. aFemales, those who had been exposed to danger, and those who had lost family or close friends were set to have a mean of 0 in the mixed effects models
