Primary outcome measures were Drinks per Drinking Day, Average Weekly Drinks, Percent Heavy Drinking Days, and PTSD symptoms. Intent-to-treat analyses compared changes in outcome measures over time between IIG and DIG as well as within-group changes. IIG participants demonstrated greater reductions in drinking (p
