Adolescents tend to overestimate the extent of peers’ unhealthy snacking consumption and such misperceptions have been associated with increased personal unhealthy snacking. This study aims to test whether a Social Norms Approach (SNA) intervention which challenges these misperceptions of peers’ unhealthy snacking will have a positive effect on students’ personal unhealthy snacking behaviours, related attitudes, and behavioural intentions.
