The dependent variables are pre- to follow-up differences in PTSD severity (PSS-I), depression (BDI), and anxiety (BAI). The independent variables are Group (coded as + ½ for B-CBT, - ½ for SC; coded as + ½ for B-CBT, - ½ for AC), Self centered pre- to post-intervention difference scores (SelfDIF, CTR), and the interaction term (SelfDIF, CTR × Group).
