Clinical Trial Summary

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. This study will be used to help build an adaptive treatment strategy to improve engagement with and effectiveness of the web-based intervention. Adaptive treatment strategies provide individualized sequences of intervention components to accommodate the changing needs of individuals based on their characteristics, treatment response, or engagement.

Description:

This study proposes to use a pilot SMART to help build an adaptive treatment strategy to improve engagement with and effectiveness of a web-based intervention for socially anxious smokers. At the outset of the study (Phase 1), participants will receive access to a new web-based smoking intervention (MyWebQuit) and will randomized to receive one of two text message services: 1) 1-way text messages, or 2) interactive, 2-way text messages. Those who disengage with the website in the first 5 weeks will be re-randomized to one of three re-engagement strategies: 1) re-engagement emails, 2) re-engagement interactive text messages, or 3) no re-engagement strategy. Outcomes include protocol feasibility, treatment acceptability, treatment utilization, and smoking cessation.
