Outcome Summary:

One study (1) has been carried out with N=1034 and a factorial design looking at the effectiveness of five interventions including 1. the Smokefree website, 2. telephone counselling, 3. e-mails containing information and motivational content, 4. a brochure with a detailed guide on planning a quit attempt and avoiding relapse, and 5. Nicotine replacement therapy (NRT), including two weeks worth of lozenges. For each participant in the study, each of these interventions could be in either the "on" (active) or "off" (control) position. The control condition for the Smokefree website was a pared down "lite" version of the website, containing only information and no skills training. The active Smokefree website was found to have a significant effect on abstinence at 3 months, but only when not combined with the active e-mail messaging intervention. The only other intervention to produce a significant effect on abstinence was NRT. This provides some evidence that the Smokefree website may be effective in promoting abstinence from smoking. 

In another study (2) N=1309 users of Smokefree were followed in an open trial over a period of 12 months. The study found that the length of time participants spent engaged with the program was significantly associated with abstinence at 12 months. Those who were still logging into the site in the 5th week had a significant 48% increased likelihood of 30 day abstinence compared to those who did not log in after the first week. This suggests the possibility of a dose response relationship for this program.
