Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The Institute for International Internet Interventions for Health (i4Health) at Palo Alto University proposes to develop digital tools specifically designed to help low income English-speaking and Spanish-speaking smokers to quit. The investigators aim to test whether a mobile-based digital intervention designed with systematic input from low-income English- and Spanish-speaking smokers from a public sector health care system can significantly improve its acceptability, utilization, and effectiveness. Using human-centered development methods, the project will involve low-income patients of the San Francisco Health Network in the design of a web app/text messaging tool. The investigators will also use participants input to improve the recruitment and dissemination strategies. i4Health will join forces with the Center for Behavioral Intervention Technologies (CBITs) at Northwestern University to iteratively develop successive versions of the digital interventions informed by our human-centered approach. The full study involves 4 successive outcome studies testing the effectiveness of the Stop Smoking San Francisco web app. The first three are single-group non-randomized pre-post studies with 1, 2, and 3-month follow-ups. These will test gradually improved versions of the app. The fourth study will involve a randomized trial comparing the initial version (the baseline version) of the web app to the final version of the web app, to determine if the final version is significantly better than the baseline version in terms of increased utilization and abstinence rates.
