Optimizing an Online Motivational Tobacco Cessation Program
The current study tested the effectiveness of four potentially important tailoring factors
(decisional framework, self-efficacy, navigation autonomy, and proactive outreach) in the
context of an online motivational intervention for smoking cessation. A fifth factor was
originally planned by dropped during intervention development due to confounds with the other
planned factors. Information learned from this study will inform how to best design an online
interventions for smoking cessation. Participants were recruited from a large, regional U.S.
health plan. Using a full factorial design to screen for important main effects and 2-way
interactions, participants were randomized to receive one of 16 different experimental factor
combinations and followed for one year to assess program impact on smokers' use of
empirically-validated cessation treatment and abstinence.

The current study is a factorial screening experiment, consistent with the Multiphase
Optimization Strategy. Participants were randomly assigned to one of 16 different
combinations of the 4 experimental factors. Each factor was explored on 2 contrasting levels.
Each contrasting factor level was then compared to the other, resulting in 4 analytic arms.
Within each arm, all participants (n = 1865) were analyzed to determine the relative effect
of each contrasting factor level on the primary and secondary outcomes of interest.
