Trial Outcomes & Findings for Twitter-enabled Mobile Messaging for Smoking Relapse Prevention (Tweet2Quit) (NCT NCT02823028)

NCT ID: NCT02823028

Last Updated: 2024-11-21

Results Overview

Percentage of participants who reported no use of tobacco products by answering the questions: 'How many cigarettes have you smoked', 'How many other tobacco products have you used', and 'How many times have you used e-cigs' since the quit date (assessed at 1, 3 and 6 months post quit date) confirmed by salivary cotinine measurement (assessed at 3 and 6 months post quit date). Note: We will apply the Russell Standard for abstinence, allowing 5 or fewer instances of tobacco use over 6 months. In our primary (most rigorous) analysis, we will consider a cotinine-positive test, regardless of source, to be non-abstinent. In additional analyses, we will code as abstinent those who assert tobacco abstinence but continue use of FDA-approved nicotine replacement therapy. In other analyses we will report results with ENDS-only users coded first as non-abstinent and then for comparison as abstinent.

Participant Flow

Participants enrolled in the coed pilot group arm (N=20), as preplanned, were not contacted for follow-up assessments. The pilot group arm was included solely to test the technical setup of the online support groups, e.g., to make sure the automated messaging and automated buddy pairing were working properly. The pilot group arm was never intended to be included in the outcome assessments.

Measure
NRT + Web Guide
NCI Smokefree.gov plus 8 weeks of combination NRT (nicotine patch plus gum/lozenges) NRT: 8-weeks of study provided NRT patch, and 8-weeks of study provided NRT gum of varying strengths or 8-weeks of study provided NRT lozenges, depending on patient level of nicotine dependence. Web Guide: A website that will provide participants with access to an evidence-based set of "base" treatment materials in one central location. The site will include information on the proper use of nicotine patches, gum, lozenges, and it will have a direct link for participants to access the NCI's Smokefree.gov Quit Guide. The website will remind participants about quit dates and send alerts via email to participants to complete the appropriate NCI Quit Guide modules.

The website will remind participants about quit dates and send alerts via email to participants to complete the appropriate NCI Quit Guide modules. Tweet2Quit: A fully automated, 90-day quit smoking intervention that provides an online, peer-to-peer support group for quitting and uses twice-daily automessages to encourage and direct the peer-to-peer exchanges. Each group will consist of 12 buddy pairs (matched on key demographics) that will be introduced via automated texts. The program will generate twice-daily programmed contacts (e.g., "what benefits do you hope to get from quitting smoking?"). Automated pattern detection software will identify and address any problematic low tweeting within a group.
