Design outcomes

Primary

Measure	Time frame
Current primary outcome measures as of 10/01/2013: Russell Standard 6 months sustained abstinence (RS6), defined as self-report of not smoking more than 5 cigarettes in the previous 6 months and no smoking in the previous week, verified by a saliva cotinine level of 14ng/ml and who also report using nicotine replacement therapy. The final follow-up at 7 months post-enrolment should ensure that participants are at least 6 months post-quit: both control and intervention websites advise upon quit dates within one month of enrolment. Six months of abstinence is endorsed by both the Cochrane review group and National Institute for Health and Clinical Excellenc (NICE) as a sufficient basis for estimating long-term abstinence. Inclusion will be by intent to treat and participants whose smoking status cannot be determined will be counted as continuing smokers. Previous primary outcome measures until 10/01/2013: Russell Standard 6 months sustained abstinence (RS6), defined as self-report of not smoking more than 5 cigarettes in the previous 6 months and no smoking in the previous week, verified by a saliva nicotinine level of <15ng/ml at 7 months follow-up. The final follow-up at 7 months post-enrolment should ensure that participants are at least 6 months post-quit: both control and intervention websites advise upon quit dates within one month of enrolment. Six months of abstinence is endorsed by both the Cochrane review group and National Institute for Health and Clinical Excellenc (NICE) as a sufficient basis for estimating long-term abstinence. Inclusion will be by intent to treat and participants whose smoking status cannot be determined will be counted as continuing smokers.	—

Secondary

Measure	Time frame
Current secondary outcome measures as of 10/01/2013: The intervention and control groups will also be compared on a number of secondary measures including: 1. Point-prevalence abstinence, defined as a self-report of not smoking in the previous 7 days at 7 months follow-up, verified by a saliva cotinine level of 14ng/ml and who also report using nicotine replacement therapy. 2. Self-report of abstinence in the previous 4 weeks at 2 months post-enrolment 3. Self-report of abstinence in the previous 3 months at 4 months post-enrolment 4. Self-report of a serious quit attempt in the previous 7 months at 7 months post-enrolment 5. Satisfaction ratings of the website at 2 and 7 months post-enrolment 6. Quantitative indices of website interaction, such as number of log-ins and page views Note: by definition, those classified as successes according to RS6 will also be classified as successes according to the secondary outcome measures 1 ? 3. Previous secondary outcome measures until 10/01/2013: The intervention and control groups will also be compared on a number of secondary measures including: 1.
