Changes in PTSD symptom clusters
Post hoc analyses were conducted on the subscales on the PCL-5 (eFig. 3). The mixed-effects model showed a significant interaction effect on all of the PCL-5 subscales. The between-group effect sizes were large for the avoidance subscale at week 3 and week 7. For the intrusion and cognitions and mood subscales, the between-group effect sizes were moderate at week 3 and large at week 7. The between-group effect size for the hyperarousal subscale was small at week 3 and moderate at week 7.
