All predictors were centered at their means. Thus, results shown are for the average participant, across conditions and Time. Coding for the dichotomous variables was the coding before centering at their means. Abstinence (PPA) was coded 1=abstinent, 0=not abstinent.

The analyses of PTSD symptoms and depression symptoms were ANCOVAs with Time having 3 levels. Thus, for these Time effects, there is no single regression coefficient for the effects in the ANCOVA. For these Time effects, we report the F statistic. For all other effects in these analyses of PTSD and depression symptoms, we report regression coefficients.

Our primary analyses for PTSD symptoms and depression symptoms did not include the moderating effects of baseline PSS-I.
