Table 2 Prediction of PTSD symptoms: Standardized beta coefficients and zero-order correlation coefficients resulting from a linear regression model on the UPID symptom severity score

From: Family violence, war, and natural disasters: A study of the effect of extreme stress on children's mental health in Sri Lanka

Predictor β Zero-order correlation p-value
Age -0.05 -0.02 0.37
Gender (female) 0.04 0.05 0.45
Economic status 0.02 -0.12 0.76
Tsunami severity 0.42 0.41 <0.001 ***
Exposure to Family Violence 0.21 0.21 <0.001 ***
Previous exposure to war 0.18 0.26 <0.01 **
  1. Note: Full model's adjusted R2 = .25; F(6.29)= 16.92, p < .0001
  2. Zero-order correlation is represented by Spearman's Rho for continuous predictor variables and point-biserial correlation for dichotomous predictor variables.
