A Systematic Review of Cognitive Dissonance-Based Interventions for Health Behavior

Le résumé fourni par la source

Unhealthy behaviors, like substance use, poor dietary intake, and physical inactivity, are highly harmful yet pervasive. Cognitive dissonance can motivate behavior change by highlighting the discrepancy between one’s behavior and its known consequences. This systematic review reports the effectiveness of dissonance-based interventions for non-clinical health behavior change. Twenty-one studies were included, most commonly targeting exercise, condom use, alcohol use, driving safety, and COVID-19 precautions. Most interventions utilized the induced compliance and/or hypocrisy induction paradigms. Sixteen (76.2%) found beneficial effects on health behaviors measured at a follow-up. The studies demonstrated moderate risk of bias, particularly in outcome assessment, as most relied on self-report measures. Nevertheless, dissonance-based interventions may be effective in eliciting health behavior change.
