PRIMARY outcome
Timeframe: Baseline to post-treatment (approx 12 weeks)Population: Differs from the total population due to missing data. Includes individuals with both time points because of the nature of the change score.
Semi-structured clinical interview assessing severity of PTSD symptoms administered by a trained, blinded assessor. The range of scores is 0-80. Mpre-Mpost is presented, so positive numbers indicate a reduction in PTSD symptom severity from before to after the intervention.

Self-report measure of anger with three major subscales (state anger, trait anger and anger control index), which are quantified as T-scores (i.e., 50 indicates the population mean with a standard deviation of 10), calculated from published adult norms tables. Change in T-scores, Tpre-Tpost, is presented, so positive numbers indicate a reduction in anger.
