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.

Detailed 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.

Interventions

Type	Name	Description
BEHAVIORAL	Phase 1: Web-based intervention (MyWebQuit) with 1-way text messages	Participants will receive MyWebQuit (web-based smoking intervention) along with a corresponding 1-way text messages
BEHAVIORAL	Phase 1: Web-based intervention (MyWebQuit) with interactive, 2-way text messages	Participants will receive MyWebQuit (web-based smoking intervention) along with corresponding interactive, 2-way text messages
BEHAVIORAL	Phase 2: re-engagement text messages	In addition to Phase 1 intervention components, 1/3 of participants who disengage with the website will receive interactive text messages designed to promote re-engagement
BEHAVIORAL	Phase 2: re-engagement emails	In addition to Phase 1 intervention components, 1/3 of participants who disengage with the website will receive a personalized email designed to promote re-engagement
