Official title

A Mobile App Based Cognitive Dissonance Intervention for Smoking Cessation

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
