CoQuit Study for Smoking Cessation

Not Applicable

Completed

• Conditions: Smoking Cessation

• Registration Number: NCT04893460
• Lead Sponsor: Oregon Research Behavioral Intervention Strategies, Inc.

Brief Summary

This study investigated the feasibility of a cognitive dissonance-based mobile app for smoking cessation (CDI). Cognitive dissonance refers to the conflict between beliefs and behaviors; interventions are designed to promote this conflict to motivate people to change their behavior. Recent research has demonstrated the efficacy and potential of using cognitive dissonance interventions for a wide range of health and behavioral problems including smoking cessation. This study developed an initial version of the CDI mobile app and evaluated the app in an evaluation study with 60 adult smokers.

Detailed Description

An initial version of the CoQuit app was developed and tested with 60 adult smokers. All participants were recruited through social media and were screened and consented online. After enrolling, participants received a link to the baseline survey which asked about past and current tobacco use, nicotine dependence, motivation to quit, cognitive dissonance and demographic information. All participants were assigned to an online support group of 5 or 6 people. The group received simultaneous invites to the app so they were able to move through the 25 day program together. The app contained short videos of a CoQuit facilitator who presented instructions for specific tasks, such as writing a brief letter to a friend or family member explaining their commitment to stop smoking. Participants recorded videos of themselves related to these activities and posted the videos within the app where they were viewed by other members of the group. All participants completed a six weeks post baseline online assessment asking about past and current tobacco use, quit attempts, as well as feedback on usability and possible improvements to the app.
