Clinical Trial Summary

The research study, "Smoker-to-Smoker (S2S) Peer Marketing and Messaging to Disseminate Tobacco Interventions" will test two smoker-driven, social marketing innovations to recruit and engage smokers in Decide2Quit.org (Decide2Quit), which is an evidence-based, effective "Digital Intervention for Smoking Cessation".

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Smoking Cessation	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	At 6 months post registration
Secondary	Change in the Number of Cigarettes Smoked	Calculated as: number of cigarettes smoked at six months minus the number of number of cigarettes smoked at baseline.	At 6 months post registration
Secondary	Repeated Use of Decide2Quit Functions	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).	Throughout study (tracked for 6 months post registration)
Secondary	Recruitment of African Americans	This is measured by the proportion of African Americans in each treatment arm	At Baseline Registration
Secondary	Recruitment Time	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).	At Baseline Registration
