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.

Outcome Measures

Primary Outcomes (2)

• Cognitive Dissonance

  Participants were asked to give a "gut-level response" to 14 words used to describe various attributes of cognitive dissonance (e.g., uncomfortable, shame). Response options for each attribute were on a 7-point scale (1 = does not apply at all, 7 = applies very much). A mean score was computed across all 14 words. A higher score was associated with greater levels of cognitive dissonance. In addition to the baseline and six-week follow-up assessment of cognitive dissonance, participants were asked five times during the 25 days of using the app. The five times were after completing the "Costs" activity on day 3, the "Quit Letter" activity on day 6, the "Planning for Pitfalls" activity on day 10, the "Staying Smoke Free" activity on day 14, and the "Letter to Youth" activity on day 19.

  Baseline, 5 times during app use (days 3, 6, 10, 14 and 19 of the 25 day program), Six weeks post baseline

• Number of Participants With Number Cigarettes Smoked Per Day

  A one-item question that asked about the number of cigarettes smoked per day. Response options were on a 6-point scale, where 1 = 5 or less, 2 = 6-10, 3 = 11-15, 4 = 16-20, 5 = 21-30, and 6 = 31 or more. A higher score indicates a greater number of cigarettes smoked per day.

  Baseline and Six Weeks Post Baseline

Secondary Outcomes (1)

• Readiness to Quit

  Baseline, 5 times during app use (days 3, 6, 10, 14 and 19 of the 25 day program), Six weeks post baseline
