SNT, STAIR plus Narrative Therapy; SSC, STAIR plus Supportive Counseling; SCNT, Supportive Counseling plus Narrative Therapy; d, Cohen’s d, where within-group effect sizes were calculated as the standardized difference of the predicted PTSD severity means at baseline and the 6 month follow-up (FU), and the standardization was based on the observed pooled standard deviation of the three treatment conditions at baseline. The pooled standard deviation of PTSD severity at baseline was 14.28.
