About this study

S2S has many innovations that are designed to utilize the power of peers and social networks for dissemination. These include: Peer recruitment: Tools to facilitate smokers' recruiting their peers to increase Decide2Quit access; and a recommender computer tailored health communication (recommender CTHC): a Complex machine learning algorithm (recommender systems) that uses smokers' feedback (explicit and implicit) in the current and prior studies to adapt its selection of messages to smokers.

Using a 2×2 factorial design, the study will compare individually and collectively the enhancements (recruitment, use, and effectiveness) offered by the S2S functions over the standard version of Decide2Quit (online recruitment and standard CTHC), an active comparison group.

Primary outcomes

  1. Smoking Cessation

    Time frame: At 6 months post registration

    Smoking cessation measured by the 7-day point prevalence question:

    Six month, 7-day point prevalence : Do you currently smoke cigarettes (smoked even 1 puff in the last 7 days)?

    • Yes
    • No
    • Don't know/not sure
    • Refused

Secondary outcomes

  1. Change in the Number of Cigarettes Smoked

    Time frame: At 6 months post registration

    Calculated as: number of cigarettes smoked at six months minus the number of number of cigarettes smoked at baseline.

  2. Repeated Use of Decide2Quit Functions

    Time frame: Throughout study (tracked for 6 months post registration)

    As measured by, an ordinal scale of number of Decide2Quit functions used after the first DISC visit (0: no functions used; 1: use of 1-2 functions, 2: > 2 functions used).

  3. Recruitment of African Americans

    Time frame: At Baseline Registration

    This is measured by the proportion of African Americans in each treatment arm

  4. Recruitment Time

    Time frame: At Baseline Registration

    Calculated as: each individual participant's recruitment date minus the date of the first participant's registration. Based on this formula, the first participant will have a recruitment time of 0 days and the last participant could have a maximum recruitment time of 3 years (1095 days).
