Study Summary

In our communications with the public, the investigators will call this the Not Quite Ready to Quit Smoking Study. One new method to increase quit attempts is to have smokers reduce their cigs/day. The investigators and others have shown that reduction aided by nicotine medications can increase quit attempts and later abstinence among smokers not ready to quit. Because half of smokers are reluctant to use nicotine medications for a non-cessation reason, the investigators now propose to test whether reduction not aided by nicotine medications can be effective. Another new method to increase quit attempts is motivational counseling. The investigators previously found implementation of the brief United States Public Health Service (USPHS) Guidelines 5 Rs motivational intervention via three 15 min phone calls can provide a large increase in quitting (OR = 6.3); however, the investigators need to replicate that result. A vendor will proactively email adult, daily smokers listed in a consumer panel to recruit 560 smokers who do not plan to quit in the next month and randomize them to a) reduction counseling without the aid of nicotine medications , b) brief counseling guided by the USPHS 5 R's, or c) usual care. The first two conditions will be delivered via brief counseling calls at study onset and then 2 and 4 weeks later (total = 35 min). The usual care condition will consist of a brief (\< 5 min) phone intervention followed by a quit guide. Our major hypothesis is that the incidence of quit attempts over the 6 months of the study will be greater in both the reduction and the motivational conditions than in the usual care condition. A secondary hypothesis is that the increase in quit attempts will lead to increased abstinence. Another secondary hypothesis is that beneficial effects of both treatments will be mediated by increases in self-efficacy and intentions to quit. A final hypothesis is that decreases in cigs/day and nicotine dependence will mediate the efficacy

Primary Outcome

The incidence of an attempt to quit smoking tobacco cigarettes during the 6 months of the study.
