The Limits and Levers of Influence: What Works in Alcohol Harm-Reduction Campaigns

Résumé fourni par la source

Alcohol harm-reduction campaigns are widely used, yet rarely produce sustained behavioral change. Synthesizing evidence from 116 studies, this article explains why campaigns often shift awareness and attitudes but fail to translate these effects into action. It introduces a Limits and Levers framework identifying four mechanisms shaping effectiveness: alignment (message-audience fit), psychological activation (emotion, efficacy, resistance), social amplification (norms, peer diffusion), and structural integration (media and environmental conditions). Findings show that campaigns underperform when designed as standalone efforts. Effectiveness increases when communication is embedded in broader systems of influence. This perspective shifts focus from whether campaigns work to how they work in practice.
