NCT01602536

Brief Summary

We conducted a two-arm (test vs. control, N=160) randomized controlled trial of small, private, online support groups for quitting smoking with 20 people per group who were seeking to quit smoking. A novel feature was a bot (auto-messenger) that posted a daily cessation-related discussion topic in each group, timed to the group's quit date.
