Hierarchical multiple linear regression model for the influence of sociodemographic factors, baseline psychopathology and changes in epistemic trust, mistrust and credulity on the mean change of PTSD symptoms (T2D).
| Step 1: Sociodemographic factors |
Step 2: Baseline psychopathology factors |
Step 3: Improved epistemic trust |
