In a subsequent study conducted entirely over the internet, Campbell, Hester and colleagues compared a cognitive-behavioral online program with components of MI called Overcoming Addictions in combination with an online and in-person mutual help group for problem drinkers called SMART Recovery (SR) (OA+SR) to SMART Recovery alone (Campbell, Hester, Lenberg, & Delaney, 2016; Hester, Lenberg, Campbell, & Delaney, 2013) in 189 heavy drinkers (AUDIT mean 24.7). Three and six-month follow-up indicated significant reductions in drinking outcomes, but no significant differences between conditions (PDA at 3 months follow up was 73.3 for OA+SR compared with 71.2 for SR only).
