Use of an online smoking cessation community promotes abstinence: Results of propensity score weighting.

ABSTRACT:

Objective

We estimated the causal effects of use of an online smoking cessation community on 30-day point prevalence abstinence at 3 months.

Methods

Participants (N = 492) were adult current smokers in the enhanced Internet arm of The iQUITT Study, a randomized trial of Internet and telephone treatment for smoking cessation. All participants accessed a Web-based smoking-cessation program that included a large, established online community. Automated tracking metrics of passive (e.g., reading forum posts, viewing member profiles) and active (e.g., writing forum posts, sending private messages) community use were extracted from the site at 3 months. Self-selected community use defines the groups of interest: "None," "Passive," and "Both" (passive + active). Inverse probability
