Content & Quality of Internet Cessation
1. To examine the quality of smoking cessation treatment on the Internet
2. To identify high-quality websitesthat warrant effectivenessevaluation
3. To adapt PHS Clinical PracticeGuideline to create anevaluation tool

Secondary Analyses
1.Early advantage for Enhanced Internet + Telephone counseling
2. Improvement in both Internet conditions over time
3.Overall performance of the comparison condition (Why did the control group do so well?)

“Integrator” Pilot Study
• N=244 randomized to EX vs. EX + SN• Intervention feasible & well received
– High ratings on positive adjectives (encouraging, welcoming, supportive)
– Low ratings on negative adjectives (annoying, intrusive, irrelevant)
– More satisfied with website
– Greater perceived helpfulness of website
• 1.7x more likely to return to the website 3+ times• 2.3x more likely to be abstinent at 30 days

Summary & Implications
1.Make sure Internet cessation program is evidence based and leverages the full functionality of the Internet
2.Seamless integration of treatments each with unique advantages rather than parallel offerings
3.Adherence is critical
