Internet and Telephone Counseling for Smoking Cessation

OBJECTIVES:

- Compare the efficacy of premium internet intervention vs premium internet with
telephone intervention vs basic internet intervention, as determined by 7-day point
prevalence abstinence at 12 months, in adult smokers.

- Compare the cost-effectiveness of these interventions in promoting smoking cessation.

- Determine the effects of internet-based interventions on measured use of the
intervention (frequency and duration of use, utilization of behavioral coping, expert
advices, and e-mail) in these patients.

- Determine the effects of internet-based interventions on variables important for
behavior change including mediators (e.g., self-efficacy, use of internet social
support) and moderators (e.g., gender, baseline motivation) of outcomes in these
patients.

OUTLINE: This is a randomized, controlled, multicenter study. Patients are stratified
according to gender and baseline motivation level. Patients are randomized to 1 of 3
intervention arms.

- Arm I (basic internet program): Patients are directed to a website of existing QuitNet™
smoking cessation materials. These materials are not tailored and have no interactive
features.

- Arm II (premium internet program): Patients receive free 6-month access to the QuitNet™
website including interactive and individualized intervention features.

- Arm III (premium internet program plus telephone counseling): Patients receive free
access to the QuitNet™ website as in arm II. Patients also receive up to 5 telephone
counseling sessions, scheduled at their convenience.

All patients are assessed at baseline and then at 3, 6, 12, and 18 months.

PROJECTED ACCRUAL: A total of 2,205 patients will be accrued for this study.
