Model Details: Using a 2×2 factorial design, we 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 that was demonstrated to be effective in our previous trial.
