Pubs, clubs and music festivals are places characterized by increased alcohol consumption. Drinkaware, a UK alcohol awareness charity, delivered two crime-prevention initiatives designed to reduce alcohol-related harm among young adults: the “Drinkaware Crew” initiative implemented at night-time economy (NTE) venues, and, more recently, the Drinkaware “Festival Crew”. This chapter uses mixed methods to present (a) an outcome evaluation of the societal impact of the “Drinkaware Crew” initiative using routinely collected data, and (b) a process evaluation examining the transferability of the “Drinkaware Crew” initiative to a music festival-context. Findings indicate that the Drinkaware Crew occupy a unique gap in existing NTE and festival infrastructures. However, several improvements to the data available are recommended to ensure that such initiatives are thoroughly evidence-based.
