Overview of evidence

Table 11 provides an overview of the efficacy of a range of interventions to prevent or reduce alcohol-related harm across the life course, ranging from universal interventions to those which are selective or targeted according to the level of risk or alcohol-related harm. Evidence suggests that a positive focus on encouraging lower risk drinking, rather than discouraging higher risk drinking, is more likely to be effective in encouraging healthier behaviour. 1

When delivered alongside interventions that equip people with the skills and resilience needed to avoid developing harmful use, the provision of accurate and relevant information can help reduce harm and inform the choices people make about alcohol. 2 This includes prevention activities delivered through a range of programmes and in a variety of settings (e.g. at home, in school, among peers, in the workplace, throughout the local community and in the media), as well as whole population approaches. 3
