Problem/Objective: Quit and Win Contests show promise in reaching large numbers of smokers and promoting quitting. Methods: This experimental pilot study determined the effect of a telephone interview during the 30-day quit period on quit rates among Quit and Win Contest registrants. Participants were recruited and randomly assigned to Treatment (two phone interviews, one during the 30-day quit period and the other during the first two months post-contest) or Control group (one phone interview post-contest). It was hypothesized that those in the Treatment group would be more successful at quitting smoking than Controls. Results: The sample consisted of 32 subjects (14 in Treatment and 18 Controls); most of the study participants were female (69%), white (94%), married (63%), and all had at least a high school education. Groups were similar on demographic characteristics, smoking history, and readiness to quit. Treatment group participants were more likely to completely quit smoking during the 30-day contest period (85%) than the Control group (35%; p = .007). Similarly, Treatment group participants were more likely than Controls to be abstinent two months after the contest period; 57% of Treatment subjects did not currently smoke cigarettes vs. 17% of Controls (p = .02). Conclusions: Although the study is limited by its small size and self-report measures, there is preliminary evidence that assessment of smoking history and current use during the Contest 30-day quit period may provide additional motivation to remain abstinent, not only during the quit period but as long as two months post-contest.
