Official title
Comparative Effectiveness of Web-based Mobile Support for the DC Tobacco Quitline
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
