±
At both time points, according to the PTDS diagnostic criteria; PTDS= Posttraumatic Diagnostic Scale (Foa, et al., 1997); RR= Relative Rate [exp(β)]; 95% CI=95% Confidence Intervals; RACHS Low risk=categories 2–3; RACHS High risk=categories 4–6;

Models are adjusted for baseline PTDS, race and parental age;
**
Models are adjusted for baseline PTDS and insurance type;
