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.

Arms Assigned Interventions
Experimental: Message Tone

Prescriptive or Motivational

Persons are randomized to receive intervention content written in either a prescriptive or motivational tone.

Behavioral: Message Tone
All participants receive an tailored, online smoking cessation program. Participants in this intervention group either receive content written in a prescriptive tone or a motivational tone.
Experimental: Testimonials
Persons are randomized to receive a personally tailored testimonial or not.
Behavioral: Testimonials
People receive a personally-tailored testimonial as part of their online smoking cessation program.
Experimental: Navigation

Dictated or Non-Dictated

Persons are randomly assigned to be able to freely navigate the website or to have their navigation of the website pre-determined based on their baseline readiness to quit smoking.

Behavioral: Navigation
Persons in this arm either have their ability to navigate the site dictated for them based on their readiness to quit smoking or they are able to freely navigate through the website.
Experimental: Proactive Outreach

Email or No-Email communication

Persons are randomized to receive periodic email reminders to return to the intervention website or not.

Behavioral: Proactive Outreach
Persons receive periodic, proactively delivered email reminders to visit the intervention website.

Detailed Description:
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.
