Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase I trial will use a pilot sequential multiple assignment randomized trial (SMART) to examine protocol feasibility and acceptability of new components of a web-based intervention for socially anxious smokers.
