Smoking Cessation Web Study: Tomando Control

This project of the University of California, San Francisco/San Francisco General Hospital Latino Mental Health Research Program is being conducted in collaboration with the University of California, San Francisco Medical Effectiveness Research Center for Diverse Populations (MERC) and the University of California, San Diego.

The Tobacco Related Disease Research Program funded the establishment of the Spanish/English Web Site for Smoking Cessation Trials at www.stopsmoking.ucsf.edu and www.dejardefumar.ucsf.edu.
 
 

Phase 1

During Phase I of the study, we created the basic site and tested its ability to: 

  1. Recruit participants
  2. Obtain informed consent
  3. Obtain initial assessment data
  4. Provide one intervention
  5. Obtain follow-up data, all with minimal human intervention. We recruited over 4500 smokers, of whom over 1000 were Spanish-speaking

Phase 2

During Phase II we carried out three sets of studies comparing two smoking cessation conditions to each other.

Publications from the first two phases include:
