Web-assisted tobacco interventions show varied results. Seeking social support and using library resources improved quit outcomes, while direct specialist contact showed negative associations in this study.
Area of Science:
- Digital Health
- Behavioral Science
- Public Health
Background:
- Web-assisted tobacco interventions (WAT-I) are increasingly used to support smoking cessation.
- Evaluating the effectiveness of specific intervention components is crucial for optimizing digital health tools.
- Resource effect studies can identify areas for improvement in informatics tools for health behavior change.
Purpose of the Study:
- To assess the impact of different functions within the Decide2Quit.org Web-assisted tobacco intervention on smoking cessation outcomes.
- To identify which intervention components are most effective in supporting smokers attempting to quit.
- To inform the design of future, large-scale randomized trials for tobacco cessation.
Main Methods:
- Recruited 204 smokers via Google advertisements for a 6-month study.
- Provided participants access to the Decide2Quit.org Web-assisted tobacco intervention.
- Tracked intervention usage and assessed 6-month smoking cessation success through rigorous follow-up.
Main Results:
- Tailored emails temporarily increased participant engagement.
- Functions supporting social support (Online Community, Family Tools), Healthcare Provider Tools, and the Library were positively associated with quit outcomes.
- Contact with Tobacco Treatment Specialists showed a negative association with quit outcomes, warranting further investigation.
Conclusions:
- Specific components of Web-assisted tobacco interventions have differential effects on smoking cessation.
- Interventions should prioritize features that facilitate social support and provide access to information resources.
- The negative impact of direct specialist contact requires further research to understand underlying mechanisms.
