Study Summary
This is a study of the effectiveness of mobile phone support for the D.C. Tobacco Quitline. The project will test the efficacy of a web-based system that uses mobile phones to improve quit rates at 3-month intervals, relative to standard quitline services. Under the standard model, relatively infrequent, periodic support is provided to smokers who want to quit and seek out the services. The new system will complement that effort by increasing the quality, frequency and accessibility of quit smoking support - when and where the smoker needs it most. It is hypothesized that successful abstinence rates will improve to the degree that participants utilize the support system and engage with the quitline.
Primary Outcome
Point-prevalent abstinence from smoking cigarettes over the past 7-days. Verified with expired carbon monoxide at 1-month. Reported by participants at 3-, 6- and 9-months.
Interventions
- BEHAVIORAL Mobile EX cessation support
- BEHAVIORAL DC Quitline Support
