Testing Alternative Stage Models of Smoking Cessation: An Intervention Study

The topic of the proposed research is adult cigarette smoking cessation. The PI has
designed a set of four smoking cessation booklets. These booklets cover different aspects
of the smoking cessation process, and are designed to help smokers who differ in their
levels of motivation to quit smoking. The purpose of the study is to compare different ways
of matching booklets to smokers who vary in their motivation to quit smoking. Adult smokers
(N=1,826) will be recruited via newspaper ads, fliers, and possibly other methods, depending
on response rates. Participants will enroll in the study by telephoning the research staff
in response to the advertisements. The smoking cessation booklets and surveys will be sent
via US Mail. Smokers will be assigned randomly to one of three intervention conditions.
Participants at baseline will answer a series of survey items regarding their motivation and
plans (or lack thereof) for quitting smoking. The three intervention conditions differ in
that each employs a different method of matching smokers to one of the four booklets.
Essentially, we are comparing different strategies for allocating booklets to smokers.
Participants will be surveyed two weeks and two months after receiving their smoking
cessation booklet.
