Note. PTSR = post traumatic stress reactivity; CI = confidence interval. Controls for month of interview and district of residence at the time of the tsunami are included. Standard errors adjust for clustering at the level of the survey community. R2 for PTSR maximum since tsunami was 0.22, for PTSR at interview it was 0.21.
