QuitNet is a commercial site providing a range of tools to assist with smoking cessation. The site offers 1) advice about quitting smoking; 2) assistance in setting a quit date; 3) specialised assessment of motivation and nicotine dependence; 4) information tailored to each user based on smoking history, motivational readiness, and demographic characteristics; 5) practical counselling including problem solving and skills training designed to enhance self-efficacy; 6) tailored assistance in selecting and using smoking cessation pharmacotherapies; and 7) social support. The support aspects of the site include an online community where users can chat, send private messages, read personal stories and get support from peers and professionals. Most parts of the site can be accessed for free, but a fee-based premium membership option provides direct access to counselling staff, use of several additional tailored expert systems, and unlimited use of the social support system.

Outcome Summary:

QuitNet has been tested in a number of uncontrolled and controlled trials, though none of these trials included a 'no treatment' control. One large scale trial (4) with N=2005 compared the effectiveness of the QuitNet site to two other conditions: i) QuitNet in conjunction with proactive telephone counselling; and, ii) a static, information-only website composed of the content of QuitNet. The QuitNet site in conjunction with telephone counselling resulted in significantly higher quit rates than either the static site or normal QuitNet site. At 18 months, the 30-day multiple point prevalence abstinence rate across all follow-up intervals was 3.5% for the basic site, 4.5% for QuitNet, and 7.7% for QuiNet plus telephone counselling. 

A recent trial in help-seeking military veterans (5) compared the efficacy of QuitNet plus access to telehealth supported nicotine replacement therapy (NRT) against face to face specialised smoking cessation care (including access to NRT). No significant difference between groups was observed in 7 day abstinence at 3 and 12 month follow up. The observed rate of abstinence in the QuitNet group was 16.8% at 3 months.

A previous observational, uncontrolled study (3) reported a 6 month quit rate of 13.2% among QuitNet users. In an uncontrolled, workplace based study (2), 13% of users reported abstinence for 7 days or more at 12 month follow up. Using the site more often and using the social support functions were associated with higher quit rates. An initial evaluation of the program, in an uncontrolled study (1) with low response rate, reported a 7-day point prevalence abstinence rate of 7% at 3-month follow-up, and a 30-day point prevalence abstinence rate of 5.9%. 

Overall, this research shows that the QuitNet site might be effective in quitting smoking, but further research with a no-intervention control condition is needed.
