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.
