Objective: To evaluate effectiveness of an Internet-based smoking cessation program as part of a comprehensive health risk reduction initiative in a large, geographically dispersed employee population.

Methods: A financial incentive for participation was offered during 2003 health benefits enrollment. The primary cessation outcome was 7-day point prevalence abstinence at 12 months.

Results: A total of 1776 employees used the Internet program. Among those surveyed, the response rate was 32%. Quit rates ranged from 13% using intention to treat analysis (nonresponders counted as smokers) to 43% among survey responders. Higher Web site utilization was associated with better cessation outcomes, even after controlling for baseline motivation.

Conclusions: The Internet program was successful at reaching a large number of geographically dispersed employees. The range of quit rates suggests that Internet cessation programs can be effective in promoting cessation and preventing relapse in a worksite setting.
