This project runs in conjunction with Phase I of Project Quit. While Project Quit focuses on tailoring messages based on a variety of theoretical constructs, this study focuses on tailoring those messages on a deeper level. Depth of tailoring is another potentially active ingredient in tailoring and refers to the level of detail of tailoring and the extent of the connections made among theory-based constructs.
