This study tested whether basic Internet (BI), Internet enhanced with tailored content and social support (EI), or enhanced Internet plus proactive telephone counseling (EI+P) would result in higher abstinence rates. The study, conducted from March 2005 through November 2008, compared the three groups of 2,005 current adults who smoked 5 or more cigarettes per day. The primary outcome measure was 30-day point prevalence abstinence measured at 3, 6, 12, and 18 month periods. At 18 months, the 30-day multiple point prevalence abstinence rate across all follow-up intervals was 3.5% (BI), 4.5% (EI), and 7.7% (EI+P), with EI+P significantly outperforming BI and EI. At 18 months, 30-day single point prevalence abstinence rates were 19.0% (BI), 17.4% (EI), and 19.6% (EI+P) and did not differ among the groups. The authors concluded that combined Internet and telephone treatment outperforms static and dynamic Internet interventions.
