P<0.001. R2 is coefficient of determination. ΔR2 is the change in R2 values from one model to another. Variables tested as predictors in the blocks: Block 1, pretrauma (demographics); Block 2, peritrauma (proximity/familiarity with the robbery); Block 3, peritrauma (perceived fear of harm and helplessness); Block 4, posttrauma (mental health problems measured by the GHQ-12).
Abbreviation: GHQ-12, General Health Questionnaire-12.
