|Linear regression analysis on the contributions of independent variables to PTSD and depression at the 36th month|
|PTSD (adjusted R2 = 0.389)||Depression (adjusted R2 = 0.404)|
|Variablesa||Beta||Partial correlation||P||Beta||Partial correlation||P|
|Subjective experiences||0.182||0.213||< 0.001||−0.033||−0.039||0.43|
|Earthquake-related loss||0.171||0.192||< 0.001||0.051||0.058||0.24|
|Perceived social support||0.062||0.070||0.15||−0.364||−0.417||< 0.001|
Note. PTSD = posttraumatic stress disorder; Beta = standardized coefficient.
a Residence, sex, and ethnicity were dummy-coded as follows: Wenchuan = 0, Mao = 1; girls = 0, boys = 1; ethnic minorities = 0, Han = 1. Objective experiences (Eq1, Eq2, Eq3 and Eq4), subjective experiences (Eq9, Eq10 and Eq11), and earthquake-related loss (Eq5, Eq6, Eq7 and Eq8) were computed by summing positive responses in each category.
