This design will allow for evaluation of whether results from our previous trial (Patten et al., in press, AJPM) can be replicated when the intervention is implemented within a "real-world" setting. That is all support person intervention calls will be delivered by the Helpline. Moreover, we will examine the potential efficacy and cost-effectiveness of a streamlined version of the intervention (i.e., 1 call). Furthermore, the proposed study will provide new data on quit attempts and cessation among the smokers. Ultimately, positive findings from this line of research could serve as the basis for expanding the range of helpline services to nonsmokers.
