This study sought feedback from teachers and adolescents on a novel intervention to reduce alcohol misuse based on the Prototype Willingness Model. A qualitative, think-aloud interview study was conducted with 17 adolescents aged 11–14 years and nine teachers. Transcripts were analysed using thematic analysis. Adolescents found the content of the intervention appealing and credible. Teachers welcomed the content and format as a means of generating discussion. ‘Moderate’ drinking appeared to be an acceptable message, although difficult to define. Enacting ‘if-then’ plans in real social situations might be challenging and representations of drinking on social media should be considered.
