  1. EoI end of intervention, FU follow up, PTSD posttraumatic stress disorder.
  2. aEstimated marginal means from multilevel models and raw standard deviations.
  3. bEffect sizes represent estimated change from the multilevel model in outcome variable from baseline to end-of-intervention and baseline to 1-month follow-up divided by the raw standard deviation in the outcome variable at baseline with a correction for small sample sizes [44].
