Summary
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.
