The objective of this study was to determine whether smokers
recruited during the New Year period differ on measures of motivation and
desire to quit, recruitment and retention rates, website utilization rates, and
short-term cessation outcomes compared to smokers recruited at other times.
Smokers visiting a Web-based cessation program during the New Year period were
more likely to register for treatment and differ on several demographic
variables, but showed similar patterns of treatment engagement, retention,
follow-up, and short-term cessation outcomes compared with participants who
visited the site during other periods of the year. These results allay
scientific concerns about recruiting participants during this time frame and
are reassuring for researchers conducting Web-based cessation trials.
