Figure 2: Symptom severity at the start and end of therapy by trauma
group on the Beck Anxiety Inventory (BAI) and Beck Depression
Inventory–II (BDI-II). Error bars represent 95% confidence intervals
for group means. Symptom severity decreased over time in both trauma
groups (main effect of time), while the absolute levels of symptom
severity were higher in the trauma group across time points (main effect
of trauma group).
We then assessed recovery rates in both trauma groups using the RCI. At
the end of therapy, across all imputed data sets, on average, 38.26% of
all patients (range across data sets: 32.06 - 42.35%) were classified
as recovered according to the RCI on the BAI and 49.76% (range across
data sets: 45.88 - 53.82%) on the BDI-II. Fisher’s exact test showed no
significant difference between the trauma groups in the rates of
recovered patients on BAI (OR = 0.59, p = .060) or BDI-II
(OR = 0.69, p = .089). Recovery classifications based on
the RCI are displayed in Figure 3.
