Summary
Introduction:
This text summarizes a three-arm randomized controlled trial that aimed to test the efficacy of a self-help intervention designed to help dual users of combustible cigarettes and electronic cigarettes (e-cigarettes) quit smoking. The study's key points address the recruitment process, study design, and outcomes, which reveal important insights about the potential benefits of targeted interventions for dual users.
Key Points:
* The study recruited 2896 participants through Facebook and multimedia advertisements.
* The three-arm randomized controlled trial compared an assessment-only group, a generic smoking cessation self-help intervention, and a targeted self-help intervention for dual users.
* Participants were randomly assigned to the groups, and intervention materials were mailed monthly for 18 months, with assessments every 3 months for 24 months.
* The main outcome was self-reported 7-day point-prevalence smoking abstinence at each assessment point.
* The targeted self-help intervention resulted in higher smoking abstinence rates than the assessment-only group throughout the treatment period.
* The generic intervention group had abstinence rates between those of the assessment and targeted groups but did not significantly differ from either when adjusted for multiple comparisons.
* Differences between study groups attenuated after the interventions ended.
Main Message:
The main message of this study is that a targeted self-help intervention specifically designed for dual users of combustible cigarettes and e-cigarettes has the potential to promote smoking cessation. This intervention, with its high potential for dissemination, could have a significant public health impact. The findings suggest that regulatory agencies should consider the potential benefits of targeted interventions for dual users in their policy considerations, as these interventions could help address the ongoing public health challenge of tobacco use.
